Questions

• A. wasn't ✓ Correct. This is a tag question that needs a negative verb tag because the main clause is positive ("It was raining"). The verb must match the tense (past: "was"), so "wasn't" is right.

• B. was ✗ Wrong. Using a positive tag after a positive statement doesn't work in English—tag questions flip between positive and negative.

• C. isn't ✗ Wrong. This is present tense, but the main clause uses past tense ("was"), so the tag must also be past tense.

• D. doesn't ✗ Wrong. This doesn't match the verb "was" at all. "Does" is for present simple and only works with action verbs, not "be."

# Explanation

Correct answer: didn't
- When a statement is positive ("You did it"), the question tag must be negative ("didn't you?")
- This is the standard rule for English question tags: they flip the polarity of the main clause

Why the others are wrong:
- B (did): This repeats the positive form instead of flipping to negative—question tags must be opposite to the statement
- C (do) and D (does): These use the base/present tense, but the statement uses past tense ("did"), so the question tag must match with "didn't"

Why A (Who) is correct:
The sentence asks about a person accompanying "she," so you need the question word for people. "Who" is the correct interrogative pronoun here.

Why the others are wrong:
- B (What) - Used for things, not people
- C (How) - Asks about manner or method, not identity
- D (Where) - Asks about location, not who someone is with

• Like (A) is correct — "like" is the standard verb used with "How do you..." to ask someone's opinion about a movie.

• Enjoy (B) — While you can enjoy a movie, "How do you enjoy the movie?" is awkward. You'd say "Did you enjoy it?" instead.

• Prefer (C) — "Prefer" needs a comparison (prefer X *to* Y), so "How do you prefer the movie?" doesn't work without saying what you're comparing it to.

• Hate (D) — Though grammatically possible, it's too extreme and negative for a neutral question about someone's opinion. "Like" is the natural choice for asking generally about feelings.

What is correct because it asks about a *thing* (a book). "What" is the interrogative pronoun for objects and ideas.

• Who asks about *people*, not objects
• Where asks about *location/place*
• When asks about *time*

What is correct because the question asks about the nature or description of the schedule itself—you want to know details about it (busy, light, complicated, etc.).

• Who asks about people, not schedules
• Why asks for reasons or causes, not schedule details
• When asks about time/timing, but here we're asking about the schedule as a whole, not when something happens

• A. wasn't it ✓ Correct. Use "was" because the main clause uses past tense ("was raining"). The tag question must match the tense.

• B. didn't it ✗ Wrong. "Didn't" suggests the action stopped, but we need a tag that matches the verb "was," not a different action verb.

• C. isn't it ✗ Wrong. "Isn't" is present tense, but the sentence is past tense ("was raining").

• D. aren't it ✗ Wrong. "Aren't" doesn't match either—it's present tense and grammatically incorrect with the singular subject "it."

Correct Answer: A. didn't you

This is a tag question that needs to match the main clause's tense and auxiliary verb. Since "did submit" uses the past tense "did," the tag must also use past tense "didn't you."

Why the others are wrong:

• B. don't you – Uses present tense, but the main clause is past tense
• C. do you – Also present tense; plus it's affirmative when it should be negative (the main clause is positive, so the tag should be negative)
• D. won't you – Uses future tense "will," which doesn't match the past tense of the main clause

Correct answer: WITH

The phrase "Who is she with?" is asking about the person's companion or who they are together with. "With" shows association or togetherness.

Why the others are wrong:
- FOR – "Who is she for?" doesn't make sense in this context; it would ask what purpose she serves
- TO – "Who is she to?" is grammatically incorrect for asking about companions
- BY – "Who is she by?" would ask about authorship or creation, not companionship

Correct answer: A. aren't they

This is a tag question (a short question added to the end of a statement). Since the main statement is positive ("Your parents are on vacation"), the tag question must be negative to create balance. The correct form is "aren't they."

Why the others are wrong:
- B. are they – Two positives in a row doesn't work grammatically; tag questions flip the polarity
- C. do they – Wrong auxiliary verb; "are" is already in the main clause, so we repeat it in the tag
- D. don't they – Wrong auxiliary verb for the same reason (plus it's also positive like the main clause)

Why A is correct:
The sentence is asking about time ("this Saturday"), so "When" is the right question word.

Why the others are wrong:
- B (Why) asks for a reason or cause—not relevant here
- C (Where) asks for location—the speaker already mentioned a time, not a place
- D (How) asks about manner or method—doesn't fit the context

Correct answer: is she

This is a tag question. When the main sentence is negative ("isn't here"), the tag question becomes positive ("is she"). They must be opposites.

Why the others are wrong:
- B (isn't she) – Wrong because you'd repeat the negative, which breaks the tag question rule
- C (will she) – Wrong tense; the main verb is "is," so the tag must use "is"
- D (won't she) – Wrong tense for the same reason, plus it's negative (you need positive)

Why A is correct:
This is a tag question. The main sentence is negative ("doesn't eat"), so the tag must be positive ("does she"). Tag questions flip the positive/negative of the main clause.

Why the others are wrong:
- B & D: "is she" and "isn't she" use the wrong verb—the sentence uses "eat," so the tag must use "do/does"
- C: "doesn't she" repeats the negative from the main clause, but tag questions require the opposite polarity

Correct Answer: A. didn't he

This is a tag question. The main clause "Bobby called you last night" uses the past tense with a positive statement, so the tag must be negative and in past tense. "Didn't he" matches perfectly.

Why the others are wrong:
- B (did he) – Wrong tense and wrong polarity. You can't use a positive tag after a positive statement.
- C (isn't he) – Wrong tense (present instead of past) and wrong verb (be instead of do).
- D (is he) – Same problems as C: wrong tense and wrong verb form.

Correct answer: A. could hear

• This is a tag question that needs to match the main clause's tense and meaning. The main clause says the audience "couldn't" (negative, past ability), so the tag question must be positive and past tense to create the contrast.

• B (can hear) – Wrong tense; uses present instead of past.

• C (couldn't hear) – Wrong because it repeats the negative from the main clause; tag questions flip from negative to positive (or vice versa).

• D (can't hear) – Wrong tense and keeps the negative instead of flipping it.

Correct Answer: A. did they

• This is a tag question (a short question added to the end of a statement). When the main statement is negative ("No one showed up"), the tag question must be positive.

• The tag uses "they" to refer back to "no one" (the subject of the sentence).

Why the others are wrong:

• B. didn't they — Wrong because tag questions flip the negativity. A negative statement needs a positive tag, not another negative one.

• C & D. "it" — Wrong because "it" doesn't match the subject. "No one" refers to people, so the pronoun must be "they," not "it."

Correct Answer: will arrive
This uses the future tense "will arrive," which matches the future time reference "soon" and forms the correct question tag structure (positive statement + negative tag "won't he?").

Why the others are wrong:
- B. won't arrive – Creates a negative statement, so the tag would be "will he?" (positive), making the sentence grammatically incorrect.
- C. arrives – Uses simple present tense, which doesn't match "soon" (a future time marker).
- D. is arriving – While "is arriving" is a valid future form, it doesn't fit as naturally with question tags in this context; "will arrive" is the standard choice.

Where is correct because the speaker is asking about the location of their book—they want to know which place it is. The clue is "I last saw it on this table," showing they're trying to find where it went.

• What asks about identity or things (What is this?), not location.
• How asks about manner or method (How do you do it?), not location.
• Why asks about reason or cause (Why did it move?), not location.

A. Where is correct because the sentence is asking about the location or place to meet. The speaker wants to know which place (museum or somewhere else) works for meeting.

B. What is wrong because it asks about things/objects, not locations—"What do you want to meet?" doesn't make sense here.

C. Who is wrong because it asks about people. We already know *who* (you and the speaker), so this question isn't needed.

D. Why is wrong because it asks for reasons. The speaker already gave a reason (going to the museum together), so this doesn't fit the context.

Why (A) is correct:
The sentence asks for a *reason* ("were you late?"), and "why" is the question word that asks for reasons or causes.

Why the others are wrong:
- When (B): Asks about *time* ("When were you late?" = what time did you arrive late?)
- Who (C): Asks about *people* (doesn't fit here)
- What (D): Asks about *things* or *general information* (doesn't fit here)
