Questions

Correct answer: A (Who)

The question "_____ said that?" is asking for the identity of the person who made a statement. "Who" is the question word for asking about people/identity.

Why the others are wrong:
- Where asks about location/place
- Why asks about reason or cause
- When asks about time

• How (correct): "How are you?" is the standard greeting asking about someone's state or condition. It's the only question word that naturally fits here.

• Why: This asks for a reason or cause ("Why are you tired?"), not someone's condition or state.

• Whose: This asks about possession or ownership ("Whose book is this?"), not relevant here.

• What: This asks for identification or information ("What is that?"), not how someone is doing or feeling.

Correct answer: Whose
- "Whose" is a possessive question word that asks about ownership or belonging—exactly what this sentence needs.
- The sentence is asking "To whom do these shoes belong?" so you need the possessive form.

Why the others are wrong:
- Why asks for a reason ("Why are they here?")
- Who asks about a person ("Who is that?"), not possession
- Where asks about location ("Where are they?")

Correct answer: A. What

• The sentence needs a question word that asks about the time of the lesson
• "What time" is the standard phrase used to ask about when something happens
• B (When) would work grammatically, but "What time" is the more natural, specific way to ask about a clock time
• C (Whom) is for asking about people as objects—doesn't fit here
• D (That) is a demonstrative/relative pronoun that doesn't form a question

Why A is correct:
"Are" is the correct form of "to be" for the second person pronoun "you" (singular or plural). The question is asking about you, so it needs the matching verb form.

Why the others are wrong:
- B (Am): Used only with "I" (first person singular), not "you"
- C (Is): Used with third person singular ("he," "she," "it"), not "you"
- D (When): This is an adverb/question word, not a verb form—it doesn't fit the grammatical structure at all

Is is correct because it's the right form of "to be" for the subject "she." In English, we use "is" with third-person singular subjects (he, she, it).

Why the others are wrong:
- Am is only used with "I" as the subject, not "she"
- Why is an adverb for asking reasons, not for forming yes/no questions about identity
- Who is a question word for asking about people's identity, but the sentence already names the person (sister), so it doesn't fit here

Correct answer: Have

This sentence needs the present perfect tense to ask about something in your possession right now. "Have you got a green car?" is the correct form.

Why the others are wrong:
- B (Had) – Past tense; this would ask about a car you owned in the past, not currently
- C (Is) – Wrong verb entirely; "is" doesn't work with "got" (you'd never say "is got")
- D (Are) – Also wrong verb; "are" doesn't pair with "got" in standard English

Correct answer: Has

This sentence needs the present perfect tense ("has got") to mean she owns a cat now. "Has" is the correct auxiliary verb for the third-person singular subject "she."

Why the others are wrong:

• Have – Used with plural subjects (they, we, you) or "I," not with "she"
• Is – This is a "to be" verb; it doesn't work with "got" for possession
• Had – This is past tense; it would mean she owned a cat before, not now

# Explanation

A. Do ✓ — Correct. With "you" (a plural or informal pronoun), we use "do" to form questions in the present tense. The structure is: "Do you [verb]?"

B. Is — Wrong. "Is" is the singular form of "to be" and doesn't pair with "you." It's used with "he," "she," or "it."

C. Has — Wrong. "Has" is used only with "he," "she," or "it" for possession or present perfect tense, never with "you."

D. Have — Wrong. While "have" can go with "you," it's used for possession or perfect tenses ("Have you eaten?"), not for general ability like speaking a language.

Why A is correct:
"Are" is the correct present tense form of "to be" used with "you." The question asks about what you're wearing right now, so we need present tense.

Why the others are wrong:
- B (Am): "Am" only goes with "I," not "you"
- C (Do): "Do" is used for actions (like "Do you like pizza?"), but "wearing" already follows the verb "be," so we don't need "do"
- D (Had): "Had" is past tense, but the sentence structure shows we need present tense ("wearing" is happening now)

Correct Answer: Did
- This question asks about a completed action in the past ("last night"), so we need the past tense form of "do" → "Did you work last night?"

Why the others are wrong:
- Have: Used for present perfect ("Have you worked?"), not simple past
- Had: Used for past perfect ("Had you worked?"), which describes an action completed before another past event—not needed here
- Are: Present tense form of "be"—wrong tense entirely since we're asking about the past

Were is correct because:
- The subject "you" requires the plural past tense form of "to be"
- "Last night" indicates past tense, so we need a past form, not present

Why the others are wrong:
- Is – present tense singular (for "he/she/it"), not past tense
- Has – present perfect tense; doesn't fit the past time reference
- Do – present tense; doesn't match "last night"

Why A is correct:
"Have" forms the present perfect tense with "been" (Have you ever been...), which asks about life experience up to now. This is the natural way to ask about visiting a place at any point in your life.

Why others are wrong:
- B (Had): Forms past perfect, which needs a specific earlier past event as reference ("Had you been to New York before you moved?"). It doesn't work for general life experience.
- C (Do): Present simple doesn't work with "been"—you can't say "Do you been."
- D (Is): This is a linking verb; it doesn't pair with "been" to form a question about experience.

Why A is correct:
"Have" matches the present tense ("don't you") in the question tag. Tag questions repeat the auxiliary verb from the main clause, and "have" is the auxiliary here.

Why the others are wrong:
- B (had): Past tense doesn't match the present tense of "don't"
- C (do): "Do" is used with action verbs, not "have" (you wouldn't say "do a cat")
- D (am): Wrong verb entirely; "am" doesn't work with "cat"

Why A (isn't) is correct:
This is a question tag. Since the statement "She is American" is positive, the tag must be negative—that's why we use "isn't." The tag always flips the positive/negative of the main clause.

Why the others are wrong:
- B & C (has/haven't): Wrong auxiliary verb. The main sentence uses "is" (present of "to be"), so the tag must also use "is/isn't"—not "have/haven't"
- D (is): This repeats the main clause instead of flipping it. A positive statement needs a negative tag question.

Who is correct.

* Who asks about a person—exactly what you need when asking "_____ said that?" You're identifying which person made the statement.
* Why asks for a reason or cause, not a person.
* When asks about time, not identity.
* Do is a verb used to form questions, but doesn't fit as the question word here (it would change the sentence structure entirely).

• How (A) is correct: This is the standard question form to ask about someone's state or condition. "How are you?" is the natural, grammatically correct greeting.

• Do (B) is wrong: "Do are you?" is grammatically incorrect. "Do" is used differently in questions (like "Do you like pizza?"), not with the verb "are."

• Have (C) is wrong: "Have are you?" doesn't make grammatical sense. These two verbs can't work together this way.

• Why (D) is wrong: While it forms a grammatical question ("Why are you?"), it's not a standard greeting and would sound odd in normal conversation.

Correct answer: Whose
- "Whose" is a possessive question word used to ask about ownership or belonging. It fits perfectly here: "Whose shoes are these?" = "Who do these shoes belong to?"

Why the others are wrong:
- Why asks for a reason, not ownership ("Why are these shoes here?" is a different question)
- Whom is an objective pronoun for people, not a possessive word for things
- Has is a verb, not a question word—it doesn't make grammatical sense in this sentence structure

Correct answer: What
- This sentence needs a question word that asks about time. "What time" is the standard phrase for asking when something happens.

Why the others are wrong:
- Why asks for a reason, not a time
- Whom is for asking about a person (object form), not time
- Have is a verb, not a question word—it doesn't fit grammatically here

Why A is correct:
"You" is a plural pronoun (or can be singular but still takes plural verb forms), so it pairs with the plural verb "are." The sentence needs a form of "to be" here, not "do."

Why the others are wrong:
- B (Is): Used with singular nouns like "he," "she," or "it"—not "you"
- C (Do): This is a helping verb, but we need a linking verb "to be" to connect "you" with "home"
- D (Am): Used only with "I," never with "you"

Why A (Is) is correct:
This sentence needs a "to be" verb to ask about possession/ownership. "Is that laptop yours?" is the correct structure—it's asking "Does that laptop belong to you?"

Why the others are wrong:
- B (Has) – "Has that laptop yours?" doesn't make grammatical sense; "has" doesn't work with the adjective "yours"
- C (Do) – "Do that laptop yours?" is incorrect; "do" requires a plural subject, and the sentence structure doesn't fit
- D (Have) – Same problem as C; "have" is for plural subjects and doesn't work here

Why A (Have) is correct:
This asks about possession in the present perfect tense. "Have you got a green car?" is the correct form—it means "Do you own a green car?" The subject "you" pairs with the auxiliary verb "have."

Why the others are wrong:
- B (Has): Used with third-person singular (he/she/it), not "you"
- C (Do): This would create "Do you got...?" which is grammatically incorrect; "do" doesn't pair with "got"
- D (Is): This would be "Is you got...?" which makes no sense and is grammatically wrong

Has is correct because "she" is a singular third-person pronoun, and "has" is the singular present tense form of "have."

• Do – used with plural subjects or "I/you," not "she"
• Are – a form of "be," not "have"; doesn't fit the meaning here
• Have – plural form; "she" needs the singular "has"

Why A is correct:
"Do" is the correct auxiliary verb for forming questions in simple present tense with "you." The structure is "Do you + verb?"

Why the others are wrong:
- B (Doesn't): This is third-person singular (he/she/it) and negative—wrong person and wrong form for a question
- C (Have): Used for perfect tenses, not simple present questions about ability
- D (Are): Used for continuous tenses (Are you speaking?) or with "to be," not simple present with action verbs

Why A is correct:
"Are" is the correct present tense form of "to be" for the second person (you). The sentence needs a present tense auxiliary verb to form a question about what you're currently wearing.

Why the others are wrong:
- B (Am): Used only with "I," not "you"
- C (Does): Used for third person singular (he/she/it) and doesn't fit with "wearing"
- D (Had): Past tense; the question asks about now, not the past

Why A is correct:
"Have" is the correct auxiliary verb for the present perfect tense with "you." The present perfect asks about experiences up to now.

Why the others are wrong:
- B (Has): "Has" is only used with third-person singular subjects (he, she, it), not "you"
- C (Had): "Had" forms the past perfect tense, which refers to something that happened before another past event—not needed here
- D (Are): "Are" is present continuous and doesn't work with "ever been"; it changes the meaning entirely
