Choice A is the best answer because it presents information about Maya civilization that is supported by the text. The text states that the writing system used in the Maya kingdoms had a symbol for the number zero. It goes on to say that at the time of the zero symbol’s earliest example, more than 2,000 years ago, almost no other writing system in the world featured such a symbol. The text also points out that some historians suggest that Maya mathematicians inherited the use of zero from the Olmec civilization, which existed in the same area as the Maya civilization at an earlier date. Thus, according to the text, some historians suggest that the Maya civilization acquired the use of zero from the Olmec civilization.

Choice B is incorrect because although the text mentions present-day historians and Maya mathematicians, it does not say anything about how much the Maya civilization respected its historians and mathematicians.

Choice C is incorrect because the text does not indicate that the Maya civilization treated its use of the zero symbol, or any other intellectual achievements, as secrets to be kept from other civilizations.

Choice D is incorrect because although the text mentions historians who suggest that the writing system of the Maya civilization inherited some features from the earlier Olmec civilization, the text does not describe any attempts of the Maya civilization to introduce its writing system to other civilizations.

Choice B is the best answer because it most logically completes the text’s discussion of Juarez. In this context, “important” means marked by significant work or consequence. The text indicates that Juarez, who was the first president of Mexico from an Indigenous community, became a certain kind of figure in Mexico’s history. It then supports that claim by describing some of the “many significant accomplishments” from Juarez’s long tenure in office. This context conveys that Juarez is a significant and consequential figure in Mexico’s history.

Choice A is incorrect because the text focuses on Juarez’s role as the first president of Mexico from an Indigenous community and on his many major accomplishments during his lengthy time in office; nothing in the text suggests that Juarez was unpredictable,” or tended to behave in ways that couldn’t be predicted.

Choice C is incorrect because nothing in the text suggests that Juarez was a particularly “secretive” figure, or that he tended to keep things private or hidden from others. Instead, the text focuses on things that are known about Juarez: that he was the first president of Mexico from an Indigenous community, that he had a lengthy tenure, and that his many major accomplishments included consolidating the national government’s authority and advancing Indigenous rights.

Choice D is incorrect because the text focuses on the idea that Juarez, who was the first president of Mexico from an Indigenous community, had many major accomplishments during his lengthy time in office. Rather than suggesting that Juarez was an “ordinary,” or common and typical, figure in Mexico’s history, this context conveys that Juarez was instead a notable figure.

Read a sentence before and after the blank to find the relevant option.

Choice C is the best answer because it most logically completes the text’s discussion of John Ashbery’s poems. As used in this context, “interpret” would mean deciphering the meaning of. The text indicates that Ashbery’s poems have many unusual features, that it’s difficult to tell what exactly the poems’ subject matter is, and that scholars strongly disagree about the poems. This context conveys the idea that it’s difficult to interpret Ashbery’s poems.

Choice A is incorrect because “delegate” means to assign someone as a representative of another person or to entrust something to someone else, neither of which would make sense in context. The text is focused only on the difficulty that readers have interpreting Ashbery’s poems due to their many
unusual features; it doesn’t suggest anything about the poems being difficult to delegate.

Choice B is incorrect because describing Ashbery’s poems as difficult to “compose,” or put together or produce, would make sense only if the text were about Ashbery’s experience of writing the poems. It could be true that it was difficult for Ashbery to compose his poems, but the text doesn’t address this; it instead discusses how readers interpret and engage with the poems.

Choice D is incorrect because describing Ashbery’s poems as being difficult to “renounce,” or give up or refuse, wouldn’t make sense in context. The text focuses on the idea that features of Ashbery’s poems are odd or unclear and have caused heated scholarly debate. This context suggests that the poems are difficult to interpret, not that the poems are difficult to renounce.

Work on your skimming skills rather than reading.

Choice C is the best answer because it most logically and precisely completes the text’s discussion of the fossil record from the Cambrian period. In this context, “abrupt” means sudden. The text explains that the fossil record reflects the unexpected appearance and rapid diversification, or increase in variety, of animal remains during the Cambrian period. This context establishes that these remains’
entry into the fossil record was sudden.

Choice A is incorrect. Although the word “explosion” appears in the name of the event marked by the fossil record change, the text never suggests that the change was “catastrophic,” or disastrous. In context, “explosion” refers to the rapid diversification, or the swift increase in variety, of animal remains in the fossil record—a phenomenon that the text presents in a relatively neutral manner, without commenting on whether it was negative or positive.

Choice B is incorrect because the text never suggests that the change toward greater diversification is “elusive,” or difficult to locate, in the fossil record. Rather, the text notes that the change occurred about 541 million years ago, suggesting that scientists have indeed been able to locate it.

Choice D is incorrect because it wouldn’t make sense in context to describe the change in the fossil record as “imminent,” or about to occur, since the text indicates that the change already occurred millions of years ago.

Read a sentence before and after the blank to find the relevant option.

Choice D is the best answer because it most logically completes the text’s discussion of baleen whale accessory spleens. In this context, “latent” means dormant or functionless. The text sets up a contrast between the idea that baleen whale accessory spleens appear not to have a function and the research
indicating that the accessory spleen may actually have a role in supporting the whales’ diving mechanisms. This context therefore conveys the idea that the assumption that baleen whale accessory spleens are latent may be incorrect.

Choice A is incorrect because it wouldn’t make sense to say that the role of the accessory spleen is “replicable,” or capable of being reproduced. The text indicates that the role of the accessory spleen seems to have no function, but some researchers think it does have a role; the text doesn’t address whether the role of the accessory spleen could or couldn’t be reproduced.

Choice B is incorrect because suggesting that the role of the accessory spleen is “predetermined,” or decided in advance, wouldn’t make sense in context. Although the researchers may agree that the role of the accessory spleen or any other organ hasn’t been determined in advance, the text focuses on the idea that the accessory spleen was thought to have been functionless but may in fact serve an active role for baleen whales.

Choice C is incorrect because it’s the opposite of what the context of the text is conveying. The second sentence of the text indicates that baleen whale accessory spleens may not be useless, not that they aren’t “operative,” or functional.

Having wide knowledge of vocabularies with quick reading skills.

Choice B is the best answer because it most accurately describes the overall structure of the text. First, the speaker describes observing a “most beautiful” sight: a tree (“black cypress”) standing out from the golden sky behind it, looking like a person’s finger “pointing upwards” and appearing “sensitive” and “exquisite.” Then the speaker wonders about the image’s meaning, asking why the finger is black and why it’s pointing upward. Thus, the text moves from the speaker’s description of a distinctive sight in nature to her pondering about what meaning to attribute to that sight.

Choice A is incorrect because the speaker assesses a natural sight—a “black cypress” tree standing “against a gold, gold sky” like a pointed finger—but doesn’t question the accuracy of her own assessment. Although she wonders why the finger, which is really a tree, is black and why it’s pointing, the speaker doesn’t suggest that her belief that the tree resembles a finger is wrong.

Choice C is incorrect. Although the speaker describes seeing a “black cypress” tree standing “against a gold, gold sky” like a pointed finger, she wonders about that natural image (asking why the finger, which is really a tree, is black and why it’s pointing) and doesn’t give any indication that any people are present in the scene.

Choice D is incorrect. Although the speaker examines and wonders about one thing in her surroundings—a “black cypress” tree standing “against a gold, gold sky” like a pointed finger—she doesn’t address her own emotional state or consider how it’s affected by her surroundings.

You should have knowledge of poetry and English to find the best answer.

Choice D is the best answer because it best describes the overall structure of the text. The speaker begins by stating that he has heard that others are accusing him of seeking to destroy institutions. The speaker then addresses this criticism by stating that he is “neither for nor against institutions.” Instead, the speaker states that his ultimate goal is to instill “the institution of the dear love of comrades” everywhere in the country. Therefore, the overall structure of the text is best described as an
address of criticism followed by an announcement of a grand ambition.

Choice A is incorrect. While the speaker does address an opinion of him that he believes to be untrue, he doesn’t indicate that this attitude has become increasingly prevalent. The speaker also concludes by explaining his goal for the future rather than his current worldview.

Choice B is incorrect because the text doesn’t portray the speaker as isolated or regretful, and the speaker gestures toward a hope for societal change but doesn’t offer an explicit prediction that it will happen.

Choice C is incorrect because the speaker addresses a criticism of him that he believes to be false; he doesn’t admit any personal shortcomings. Moreover, the speaker concludes by stating a goal he has rather than showcasing his achievements.

Choice B is the best answer because it most accurately describes the function of the third sentence within the overall structure of the text. The third sentence makes a generalization, asserting that evolutionary links between predators and prey can persist across great expanses of time and distance. This generalization is exemplified by the text’s discussion of the relationship between mimosa trees and B. terrenus beetles. When mimosa trees were introduced to North America in 1785, no B. terrenus beetles were present, so the relationship between the trees and the beetles that exists in their native East Asia was disrupted. When the beetles were introduced to North America more than 200 years later, however, they quickly attacked mimosa trees, illustrating the generalization that links between predators and prey “can persist across centuries and continents.”

Choice A is incorrect because the third sentence doesn’t indicate that Chang and colleagues were investigating any particular hypothesis. According to the text, Chang and colleagues were simply monitoring mimosa trees when the beetles happened to be introduced to the area.

Choice C is incorrect because the third sentence offers a generalization about the relationship between predators and prey, not an explanation for the findings of Chang and colleagues that differs from an explanation presented elsewhere in the text.

Choice D is incorrect because the third sentence doesn’t discuss any particular species (either the species mentioned elsewhere in the text or any other) and doesn’t help explain why species spread to new locations.

Read the one sentence before and after to underlined sentence to find the best answer.

Choice B is the best answer because it describes the most likely way that Graeber and Wengrow (Text 2) would respond to the “conventional wisdom” presented in Text 1. According to Text 1, the conventional wisdom about human social systems is that they developed through stages, beginning with hunter-gatherer bands, then moving to clan associations, then chiefdoms, and finally arriving at states with bureaucratic structures. Text 2 indicates that Graeber and Wengrow believe that human social systems have been flexible, shifting between different types of structures, including both hierarchical and collective systems, and that these shifts may have even occurred seasonally. This suggests that Graeber and Wengrow would dispute the idea that developments in social structures have followed a linear progression through distinct stages.

Choice A is incorrect because nothing in Text 2 suggests that Graeber and Wengrow believe that decentralized collective societies are more significant than hierarchical systems. Text 2 is focused on Graeber and Wengrow’s view that humans have flexibly shifted among various social structures, not on the importance of particular structures relative to others.

Choice C is incorrect because Text 2 doesn’t include any information suggesting that Graeber and Wengrow believe that hierarchies didn’t emerge until after the rise of agriculture. In fact, Text 2 indicates that Graeber and Wengrow cite evidence suggesting that some hunter-gatherer groups formed social structures with hierarchical elements (“communities that included esteemed individuals”) 50,000 years ago, long before the rise of agriculture, which Text 1 says occurred around 12,000 years ago.

These questions are time-consuming. If it consumes your time, guess the answer. The higher the rank, the more score you will get.

Choice D is the best answer because it most accurately states the main idea of the text. The text describes Mary’s activities in an overgrown hidden garden, saying that she was “very much absorbed” and was “only becoming more pleased with her work every hour” rather than getting tired of it. She also thinks of garden activities as a “fascinating sort of play.” Thus, the main idea of the text is that Mary feels very satisfied when taking care of the garden.

Choice A is incorrect because the text never makes any mention of Mary’s chores.

Choice B is incorrect because the text indicates that Mary finds pulling up weeds to be fascinating, not boring.

Choice C is incorrect because Mary thinks of garden activities in and of themselves as play, not as something necessary to do to create a space to play.

Improve your reading skills by practicing more and more.

Choice C is the best answer because it describes something that is true of Mother, as presented in the text. The text indicates that in addition to other activities, Mother writes stories for her children while they are at school and makes up “funny pieces of poetry” for certain occasions.

Choice A is incorrect because the text suggests that Mother prefers to spend her time with her children and doesn’t sit at home hoping that ladies will visit her.

Choice B is incorrect because the text says only that Mother makes up poetry for the children’s birthdays, not that she likes birthdays more than other special occasions.

Choice D is incorrect because the text doesn’t suggest that Mother prefers reading to her children over the other activities she does with them, such as playing with them and writing stories and poems for them.

Whichever way suits you? (1) Take a look at the options, understand the sense of them then skim the paragraph to find the correct option. (2) Skim first and find the answer then look for the correct option.

Choice A is the best answer because it most accurately states the main purpose of the text. In the first part of the text, the speaker addresses Paul Laurence Dunbar’s ability to understand people (he has “read the hearts and souls of men” and written of their “joy and mirth”). In the second part of the text, the speaker describes Dunbar’s thorough understanding of the natural world (he has read “the
language of the flowers” and engaged with “the little brook”). Thus, the text mainly praises Dunbar for being especially perceptive about people and nature.

Choice B is incorrect because the speaker describes Dunbar as having read the “hearts and souls of men” and the “language of flowers” to convey Dunbar’s ability to comprehend people and nature, not to suggest that Dunbar has literally read any of these things or has read a great deal about them.

Choice C is incorrect because the text notes how well Dunbar has made sense of the topics he’s written about but doesn’t address any specific parts of Dunbar’s writing process beyond the suggestion that he used a pen.

Choice D is incorrect because the text focuses on Dunbar’s understanding of people and nature as expressed in his writing. Nothing in the text suggests that the speaker is recalling a particular afternoon actually spent in nature with Dunbar; even if there had been a shared experience, the text isn’t focused on reminiscing.

For doing this, the study of understanding English Literature is useful, or the study of key referencing skills.

Choice A is the best answer because it presents the quotation that most directly illustrates the claim that Whitman’s poem suggests that its readers haven’t fully understood themselves. This quotation makes that point directly by saying to readers, “You have not known what you are.” The quotation goes on to reinforce this point using a metaphor of sleep, saying that readers have “slumber’d” and
that their “eyelids have been the same as closed most of the time.”

Choice B is incorrect because this quotation doesn’t suggest that readers haven’t fully understood themselves but instead characterizes readers as “immense” and “interminable.” Although immense and interminable things can be difficult to understand, this quotation doesn’t make that point.

Choice C is incorrect because this quotation doesn’t suggest that readers haven’t fully understood themselves but instead conveys the speaker’s regret over not having celebrated readers sooner. In fact, this quotation says nothing at all about readers themselves—it’s focused solely on the speaker’s feelings about readers.

Choice D is incorrect because this quotation doesn’t suggest that readers haven’t fully understood themselves; instead, this quotation makes the point that the speaker has understood readers and is determined to create “hymns” about them.

Read the paragraph and find the best option.

Choice A is the best answer because it presents a finding that, if true, would support the claim about Chambi’s photographs. The text describes a student advancing the claim that Chambi’s photographs “have considerable ethnographic value”—meaning that they are valuable as records of cultures—and that they “capture diverse elements of Peruvian society” in a respectful way. If it’s true that Chambi carefully photographed people from a range of different communities in Peru as well as photographed the customs and sites of different communities, that would lend support to the claim that the photographs have ethnographic value as depictions of diverse elements of society in Peru.

Choice B is incorrect because the student’s claim is that Chambi’s photographs have considerable ethnographic value because they depict diverse elements of Peruvian society; the student doesn’t claim anything about the technical skill demonstrated in the photographs.

Choice C is incorrect because neither Chambi’s reputation nor the locations where his photographs may have been published would be relevant to the student’s claim that his photographs are valuable as an ethnographic record of Peru’s diverse society.

Choice D is incorrect because the popularity among other photographers of the people and places that Chambi photographed would be irrelevant to the student’s claim that Chambi’s photographs are valuable as an ethnographic record of Peru’s diverse society.

Read the paragraph and find the best option.

Choice C is the best answer because it uses data from the table to effectively exemplify the idea that the film outputs of the four individuals included in the table should be considered bare minimums—that is, that we should assume that the individuals actually had higher outputs than those recorded. The table presents the years during which the individuals were active and the number of known films the individuals are credited in. The table indicates that Lillian St. Cyr has 66 film credits as an actor and that Edwin Carewe has 58 film credits as a director; it follows that if some films and records for the era were lost, it’s possible that Lillian St. Cyr acted in far more than 66 films and that Edwin Carewe directed more than 58 films.

Choice A is incorrect because it doesn’t effectively exemplify the idea that the film outputs of the four individuals included in the table should be considered bare minimums. Rather than addressing the idea that the individuals likely had higher outputs than those presented in the table, this choice simply compares data from the table to make the point that Dark Cloud has fewer credited acting
roles than Lillian St. Cyr (35 and 66, respectively).

Choice B is incorrect because it misrepresents data from the table, even though it may exemplify the idea that the film outputs of the four individuals included in the table should be considered bare minimums by implying that Edwin Carewe acted in more than 47 films. The table indicates that Edwin Carewe was active from 1912 to 1934, meaning that his 47 credited acting roles were in films made before or during 1934, not after that time.

Choice D is incorrect because it doesn’t effectively exemplify the idea that the film outputs of the four individuals included in the table should be considered bare minimums. Instead of addressing the idea that the individuals likely had higher outputs than those recorded, this choice suggests that James Young Deer actually acted in and directed fewer films than presented in the table (only 33 known films as a director instead of 35, and only 10 known films as an actor instead of 33).

Time-consuming question but if you have enough practice, you can solve it in no time. Remember, the higher the questions, the higher marks it keeps.

Choice A is the best answer. The convention being tested is the coordination of clauses within a sentence. This choice correctly uses a comma and the coordinating conjunction “but” to join a main clause (“Typically…value”) and a subordinate clause (“when…Whitman”) that precedes a main clause (“such… scholars”).

Choice B is incorrect because it results in a run-on sentence. A main clause is fused without punctuation and/or a conjunction to a subordinate clause that precedes a main clause.

Choice C is incorrect because it results in a comma splice. A comma can’t be used in this way to mark the boundary between a main clause and a subordinate clause that precedes a main clause.

Choice D is incorrect. Without a comma preceding it, the conjunction “but” can’t be used in this way to join a main clause and a subordinate clause that precedes a main clause.

You should learn Parts of Speech, especially Noun; Conjunction, and Punctuation.

Choice C is the best answer. The convention being tested is punctuation use between sentences. In this choice, the period after “percent” is used correctly to mark the boundary between one sentence (“After… percent”) and another (“Such…up”).

Choice A is incorrect because it results in a comma splice. A comma can’t be used in this way to mark the boundary between sentences.

Choice B is incorrect. Without a comma preceding it, the conjunction “and” can’t be used in this way to join sentences.

Choice D is incorrect because it results in a run-on sentence. The sentences (“After…percent” and “Such…up”) are fused without punctuation and/or a conjunction.

You should learn Parts of Speech, especially Adverb; Conjunction, and Punctuation.

Choice D is the best answer. The convention being tested is punctuation between a verb and a preposition. When, as in this case, a verb (“is added”) is immediately followed by a preposition (“whenever”), no punctuation is needed.

Choice A is incorrect because no punctuation is needed between the verb and the preposition.

Choice B is incorrect because no punctuation is needed between the verb and the preposition.

Choice C is incorrect because no punctuation is needed between the verb and the preposition.

You should learn Parts of Speech, especially Adverb; Conjunction, Punctuation, and Clauses.

Choice A is the best answer. The convention being tested is subject-verb agreement. The singular verb “has enhanced” agrees in number with the singular subject “A Sheaf Gleaned in French Fields,” which is the title of a book of poems.

Choice B is incorrect because the plural verb “are enhancing” doesn’t agree in number with the singular subject “A Sheaf Gleaned in French Fields.”

Choice C is incorrect because the plural verb “have enhanced” doesn’t agree in number with the singular subject “A Sheaf Gleaned in French Fields.”

Choice D is incorrect because the plural verb “enhance” doesn’t agree in number with the singular subject “A Sheaf Gleaned in French Fields.”

You should learn the Present Tense to better understand this. Learn Tenses also.

Choice C is the best answer. The convention being tested is punctuation use between a main clause and two supplementary elements. In this choice, the commas after “nickname” and “however” are correctly used to separate the supplementary adverb “however” from the main clause (“Scott-Heron…nickname”) on one side and the supplementary participial phrase (“feeling…bluesologist”) on the other.

Choice A is incorrect because it fails to mark the boundary between the supplementary adverb “however” and the supplementary phrase (“feeling…bluesologist”).

Choice B is incorrect because a semicolon can’t be used in this way to join the supplementary adverb “however” and the supplementary phrase (“feeling…bluesologist”).

Choice D is incorrect because a semicolon can’t be used in this way to join the main clause (“Scott-Heron…nickname”) and the supplementary word and phrase (“however” and “feeling…bluesologist”). Moreover, placing the semicolon after “nickname” illogically signals that the following information (Scott-Heron’s feeling that the nickname didn’t encapsulate his devotion to the blues tradition) is contrary to the information in the previous clause (Scott-Heron’s resistance to the nickname).

Choice C is the best answer. “In addition” logically signals that the claim in this sentence—that the Inca of South America may have used quipus to record more complex information—is an additional point related to the previous statement about the Inca using quipus to record countable information.

Choice A is incorrect because “as a result” illogically signals that the claim in the sentence is a consequence or result of the previous statement about the Incas using quipus to record countable information. Instead, the possibility that the Inca used quipus to record more complex information is an additional point about how the quipus were used.

Choice B is incorrect because “in other words” illogically signals that the claim in the sentence is merely a paraphrase or restatement of the previous statement about the Incas using quipus to record countable information. Instead, the possibility that the Inca used quipus to record more complex
information is an additional point about how the quipus were used.

Choice D is incorrect because “for example” illogically signals that the claim in the sentence
exemplifies the previous statement about the Incas using quipus to record countable information. Instead, the possibility that the Inca used quipus to record more complex information is an additional point about how the quipus were used.

Choice B is the best answer. “Then” signals that this sentence’s claim about Darwin and Wallace follows logically from the previous information. In other words, both scientists independently arriving at the theory of natural selection was, arguably, an expected outcome of the circumstances mentioned in the previous sentence.

Choice A is incorrect because “however” illogically signals that the claim in this sentence contrasts with the previous information about the ideas circulating among British scientists in the 1800s. Instead, this claim follows logically from that information.

Choice C is incorrect because “moreover” illogically signals that the claim in this sentence merely adds to the previous information about the ideas circulating among British scientists in the 1800s. Instead, this claim follows logically from that information.

Choice D is incorrect because “for example” illogically signals that this sentence provides an example supporting the previous information about the ideas circulating among British scientists in the 1800s.
Instead, it presents a claim that follows logically from that information.

Choice A is the best answer. The sentence emphasizes Janaki Ammal’s achievement, explaining that she successfully created sugarcane hybrids that are well suited to India’s climate by crossbreeding an imported sugarcane species with grasses native to India.

Choice B is incorrect. The sentence emphasizes the goal of the Imperial Sugar Cane Institute in the 1930s; it doesn’t emphasize Janaki Ammal’s achievement.

Choice C is incorrect. While the sentence mentions Ammal, it doesn’t emphasize her achievement of successfully creating sugarcane hybrids.

Choice D is incorrect. While the sentence mentions the achievement of crossbreeding imported sugarcane species with grasses native to India, it doesn’t emphasize the achievement as belonging to Janaki Ammal.

Choice B is the best answer. The sentence emphasizes a similarity between the sculptures Recognition and Students Aspire, noting that both sculptures show African American figures in poses that symbolize supportive relationships.

Choice A is incorrect. The sentence describes one of the sculptures; it doesn’t emphasize a similarity between the two sculptures.

Choice C is incorrect. The sentence specifies the different years the sculptures were completed in; it doesn’t emphasize a similarity between the two sculptures.

Choice D is incorrect. The sentence emphasizes a difference between the two sculptures, noting that the figures in the sculptures have different feature definitions; it doesn’t emphasize a similarity between the two sculptures.

Choice D is the best answer. The sentence emphasizes the difference between baking soda and baking powder, noting that baking soda needs to be mixed with an acidic ingredient to produce carbon dioxide but baking powder doesn’t.

Choice A is incorrect. The sentence focuses on what bakers use to make batters rise; it doesn’t emphasize the difference between baking soda and baking powder.

Choice B is incorrect. The sentence provides a general description of baking soda and baking powder; it doesn’t emphasize the difference between them.

Choice C is incorrect. The sentence explains what baking soda and honey are; it doesn’t emphasize the difference between baking soda and baking powder.

Choice D is the best answer. The sentence effectively describes Unwoven Light to an audience unfamiliar with Park, noting that Soo Sunny Park is a Korean American artist and that the 2013 work consists of colorful prisms formed by light passing through iridescent tiles.

Choice A is incorrect. The sentence describes aspects of Unwoven Light but doesn’t mention who Park is; it thus doesn’t effectively describe the work to an audience unfamiliar with Park.

Choice B is incorrect. Although the sentence indicates when the work was created and who Park is, it lacks descriptive details and thus doesn’t effectively describe Unwoven Light.

Choice C is incorrect. The sentence mentions Park and describes an aspect of Unwoven Light—the chainlink fence—but doesn’t effectively describe the overall work to an audience unfamiliar with the artist.

Choice C is the best answer. The sentence effectively presents Tan’s research to an audience unfamiliar with Angkor Wat, explaining the results of the research and identifying Angkor Wat as a temple in Cambodia.

Choice A is incorrect. While the sentence presents Tan’s research, it fails to explain what Angkor Wat is for an audience unfamiliar with the temple.

Choice B is incorrect. The sentence emphasizes the role that decorrelation stretch analysis played in Tan’s research; it doesn’t present the research, which would require specifying where it was conducted.

Choice D is incorrect. While the sentence explains what Angkor Wat is, it fails to present Tan’s research.
