Question 1
You ____ wear a seat belt in the car. It's the law.
Correct answer: B
Must expresses a rule or obligation. Might and could only show possibility, which does not match It's the law.
-
Question 2
I ____ swim when I was three, but now I'm a strong swimmer.
Correct answer: A
Couldn't is the past of can't and describes a lack of ability in the past. The other modals are about rules or necessity, not ability.
-
Question 3
Visitors ____ feed the animals. It makes them sick.
Correct answer: D
Feeding the animals is forbidden, so the answer is mustn't. Don't have to would mean feeding them is optional, which is the opposite of the message.
-
Question 4
It's very cloudy. It ____ rain this afternoon, so take a jacket.
Correct answer: C
Might shows a possibility in the future. Can't would say rain is impossible, which does not fit the advice to take a jacket.
-
Question 5
The lights are off and nobody answers the door. They ____ be at home.
Correct answer: A
For a negative guess based on evidence, American English uses can't: they are almost certainly not home. Mustn't means "not allowed", not a guess.
-
Question 6
You ____ bring food. Lunch is included in the price.
Correct answer: B
Bringing food is unnecessary, not forbidden, so use don't have to. Mustn't would mean you are not allowed to bring food.
-
Question 7
I'm not sure where Jake is. He ____ have gone to the gym.
Correct answer: A
Might have + past participle is a guess about the past when you are not sure, which matches I'm not sure. Should have gone would be a criticism.
-
Question 8
Her flight landed at noon, and the drive home takes thirty minutes. It's 3 p.m. now, so she ____ have arrived home by now.
Correct answer: C
Must have + past participle is a confident guess about the past. With three hours for a thirty-minute drive, she is almost certainly home, so can't have is the opposite.
-
Question 9
"____ you like some more coffee?"
Correct answer: D
Would you like ...? is the polite way to offer something. Will you like is not used for offers.
-
Question 10
You ____ have bought me flowers, but thank you, they're beautiful.
Correct answer: B
Needn't have + past participle means someone did something that was not necessary. The speaker got the flowers and thanks the person, so can't have or couldn't have make no sense.
Questions you leave blank are not counted as wrong.
