Quiz Question, Answer and Explanation
Note: Do remember in the quiz box above, the questions and options will shuffle, so they won’t have the same sequence like 1, 2, 3, or A, B, C as below.
1. After the error was discovered, they had to __ the changes by hand.
A) undo B) undid C) undone D) undoe
Verb (forms & meaning): undo — V1 undo, V2 undid, V3 undone. To reverse an action or restore to a previous state.
Correct: A) undo. Because the sentence uses the modal construction “had to __,” it requires the base form after “to” (infinitive). “Had to undo the changes” means they were obliged to reverse what had been done.
Why B) undid is wrong: “Undid” is the simple past; it cannot follow “to” which needs the base/infinite form in this context.
Why C) undone is wrong: “Undone” is the past participle and would be used with auxiliaries (e.g., “had undone”), not directly after “to.”
Why D) undoe is wrong: Misspelling and invalid form.
2. The professor __ algebra to a generation of students before retiring.
A) taught B) teach C) teached D) teaching
Verb (forms & meaning): teach — V1 teach, V2 taught, V3 taught. To instruct or give knowledge.
Correct: A) taught. The sentence describes a past career span, so the simple past taught correctly places the teaching activity in the past and indicates completion.
Why B) teach is wrong: The base form is not used to narrate past completed careers without auxiliary context.
Why C) teached is wrong: Incorrect regularized form; the correct irregular past is taught.
Why D) teaching is wrong: Present participle/gerund which would change construction and not fit the simple past narrative.
3. The freighter had slowly __ beneath the waves before any rescue team could reach it.
A) sunk B) sank C) sink D) sunked
Verb (forms & meaning): sink — V1 sink, V2 sank, V3 sunk. To descend below the surface of a liquid.
Correct: A) sunk. After “had” we need the past participle, which for sink is sunk; “had sunk” indicates the ship went under prior to the arrival of rescuers. This distinguishes the sinking as completed earlier.
Why B) sank is wrong: “Sank” is simple past and cannot follow “had”; the past perfect requires the participle.
Why C) sink is wrong: Base form is not grammatical here.
Why D) sunked is wrong: Nonexistent form; sink is irregular and does not take -ed.
4. He __ the letter in half in anger and threw it away.
A) tore B) tear C) torn D) teared
Verb (forms & meaning): tear — V1 tear, V2 tore, V3 torn. To rip or pull apart.
Correct: A) tore. The simple past “tore” indicates a completed physical action in the past, matching the narrative “and threw it away.” It places the ripping event before the throwing.
Why B) tear is wrong: Base form cannot express the past action without auxiliary context.
Why C) torn is wrong: “Torn” is the past participle and would need an auxiliary (e.g., “had torn” or “was torn”) to be correct here.
Why D) teared is wrong: “Teared” typically means “caused to have tears” (rare) and is not the correct past of tear; it’s a mistaken regularization.
5. He admitted he had __ her about the meeting time.
A) told B) tell C) telled D) telling
Verb (forms & meaning): tell — V1 tell, V2 told, V3 told. To communicate information to someone.
Correct: A) told. The past perfect “had ___” requires the past participle; told works here and expresses that he had already given the information (or claimed he did) before admitting the error.
Why B) tell is wrong: The base form cannot follow “had” to form the past perfect.
Why C) telled is wrong: Incorrect form; the irregular past is told, not a -ed form.
Why D) telling is wrong: Present participle; it would yield a different meaning and structure (e.g., “was telling”).
6. Let the board __ critical documents from the public record.
A) withhold B) withheld C) withholded D) withholding
Verb (forms & meaning): withhold — V1 withhold, V2 withheld, V3 withheld. To refuse to give or release.
Correct: A) withhold. Let requires V1; withhold indicates the board has permission to keep documents back prior to scrutiny. It communicates deliberate general action with present implications.
Why B) withheld is wrong: Past or Past Participle form cannot follow “Let” alone.
Why C) withholded is wrong: Incorrect regularization; the verb is irregular.
Why D) withholding is wrong: Present participle indicates ongoing withholding and would not fit the causative “Let” construction.
7. The thief had __ the envelope with a small slit so no one noticed.
A) slit B) slitted C) slitten D) sliting
Verb (forms & meaning): slit — V1 slit, V2 slit, V3 slit. To make a long, narrow cut.
Correct: A) slit. This irregular verb keeps the same form for base, past, and participle. After “had,” the participle slit is called for; it indicates the envelope had already been opened covertly.
Why B) slitted is wrong: Regularization that is not standard for this verb; “slit” is correct.
Why C) slitten is wrong: Not an acceptable English form.
Why D) sliting is wrong: Present participle/gerund; would indicate ongoing cutting, not the completed action.
8. By dusk the family had __ at the graveside for hours.
A) wept B) weep C) wepted D) weeping
Verb (forms & meaning): weep — V1 weep, V2 wept, V3 wept. To shed tears due to sorrow.
Correct: A) wept. Past perfect or simple past contexts call for the appropriate past form; here “had wept” or “had __ for hours” uses wept to indicate the prolonged sorrow occurred earlier and was completed relative to dusk. It communicates the intensity and duration of grief.
Why B) weep is wrong: Base form cannot follow “had.”
Why C) wepted is wrong: Incorrect formation; weep is irregular.
Why D) weeping is wrong: Present participle; would change aspect (progressive) rather than the completed sense.
9. The carpenter had forcefully __ the dowel into the hole before the
A) thrust B) thrusted C) thrusting D) thrusten
Verb (forms & meaning): thrust — V1 thrust, V2 thrust, V3 thrust. To push or drive something forcibly.
Correct: A) thrust. Thrust uses the same form across base, past, and participle; in the past perfect slot after “had,” thrust is correct and tells us the dowel was already forced into place prior to the glue setting.
Why B) thrusted is wrong: Not standard; the correct form is thrust.
Why C) thrusting is wrong: Present participle; would indicate an action in progress rather than completed.
Why D) thrusten is wrong: Nonstandard and not accepted.
10. He insisted he had __ the embarrassing remark and wished it hadn’t been broadcast.
A) unheard B) unhear C) unheared D) unhearing
Verb (forms & meaning): unhear is rare; more commonly we use the adjective unheard (not heard). For the purposes of this clause, treat unheard as the adjective/past-participle-like form meaning “not heard or reversed in effect.”
Correct: A) unheard. The sentence claims he had not heard (or had managed to make it unheard) prior to the telecast; the chosen form unheard functions as the past-participial adjective that matches “had __” in meaning. It indicates the state of not being heard or having been rendered inaudible, which is why he regrets the broadcast.
Why B) unhear is wrong: “Unhear” as a base verb is uncommon and nonstandard; it does not fit natural English here.
Why C) unheared is wrong: Incorrect spelling/formation; the correct adjective is unheard.
Why D) unhearing is wrong: Present participle is awkward and does not suit the past-state meaning required by the sentence.
