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. By next June, I __ this documentary for over a year.
A) shall have been researching
B) will have been researched
C) shall have researched
D) shall be researching
Verb: research (verb) — to study a subject in detail to discover new information; researcher (noun).
A) Correct: “Shall have been researching” is perfect continuous and used with “I”. It expresses an action that started in the past, continues in the present, and will still be ongoing until next June.
B) Wrong: “Will have been researched” is passive voice + continuous but nonsensical because a person researches something, the documentary does not get researched by itself. Also, the subject “I” cannot fit with passive.
C) Wrong: “Shall have researched” is Future Perfect, NOT Continuous. It expresses completed action, not ongoing work. The question requires “for over a year,” indicating duration.
D) Wrong: “Shall be researching” is Future Continuous, not Future Perfect Continuous. It only expresses action in progress at a future point, not extended duration up to that point.
2. They __ the forest route for three months before the snow arrives.
A) will have been mapping
B) will be mapped
C) shall have been mapping
D) will have mapped
Verb: map (verb) — to create or chart an area; map (noun).
A) Correct: “Will have been mapping” accurately expresses a long action continuing up to a specific future time.
B) Wrong: Passive construction “will be mapped” describes the route being mapped BY someone, not “they” doing the mapping.
C) Wrong: “Shall” is only for “I/We” in this quiz; using it with “they” is grammatically incorrect per instruction.
D) Wrong: “Will have mapped” is Future Perfect (completed), but the sentence needs continuous duration “for three months,” so it fails.

A) shall have been coordinating
B) will have been coordinated
C) shall be coordinating
D) will have coordinated
Verb: coordinate — verb; to organize various parts to work together.
A) Correct: “Shall have been coordinating” fits “we” and expresses ongoing duration.
B) Wrong: “Will have been coordinated” is passive + continuous but changes meaning: it would mean someone coordinates us.
C) Wrong: Future Continuous, not Perfect Continuous; it does not show action continuing up to a point.
