1.
Choose the sentence below that is closest in meaning to this sentence:I think they're angry.
A) They must not be angry.
B) They must be angry.
C) They can't be angry.
D) None of the above.
Show Answer
Explanations:
The sentence "I think they're angry" expresses a degree of certainty that is not as strong as "They must be angry." However, it indicates a belief that the individuals are indeed angry. Option B aligns with this idea by using "must," which conveys a high level of certainty.
Option Analysis:
Option A:
This suggests they are not angry, contradicting the original sentence's implication.
Option B:
Correct. Uses "must" to indicate strong certainty that aligns with thinking someone is angry.
Option C:
Implies they cannot be angry, which directly contradicts the original thought.
Option D:
Incorrect as Option B is correct.
2.
Choose the sentence below that is closest in meaning to this sentence:She's probably at lunch.
A) She might be at lunch.
B) She must be at lunch.
C) She can't be at lunch.
D) None of the above.
Show Answer
Explanations:
Option A, "She might be at lunch," is the closest in meaning to the original sentence because both express a degree of uncertainty about her location during lunchtime. The modal verb "might" indicates a possibility without strong certainty, aligning with the probable but not confirmed status implied by "probably."
Option Analysis:
Option A:
Correct. Uses "might," indicating possibility.
Option B:
Incorrect. "Must" implies certainty, which contradicts the original sentence's uncertainty.
Option C:
Incorrect. "Can't" indicates impossibility, contradicting the probable status in the original sentence.
Option D:
Incorrect. Suggests none are correct, but Option A is valid.
3.
Choose the sentence below that is closest in meaning to this sentence:That's impossible! I don't believe she's back from the meeting already!
A) She must not be back from the meeting already!.
B) She can't be back from the meeting already!.
C) She might be back from the meeting already!.
D) None of the above.
Show Answer
Explanations:
Option B is correct because "can't" expresses a strong disbelief or impossibility, which aligns with the original sentence's sentiment that the speaker does not believe she has returned from the meeting already.
Option Analysis:
Option A:
"must not" implies a stronger obligation than the original sentence conveys. The original expresses disbelief rather than an absolute prohibition.
Option B:
"can't" accurately reflects the speaker's strong disbelief or impossibility, matching the original sentence's tone.
Option C:
"might" suggests a possibility, which contradicts the original sentence's certainty of disbelief.
Option D:
is incorrect as Option B is valid.
4.
Ben is trying to ignore Rochelle. He ..... want to hear the gossip.
A) Must.
B) Must not.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence indicates that Ben does not want to hear the gossip, which means he has a strong desire or intention to avoid it. The modal verb "must" is used to express necessity or obligation, while "must not" expresses prohibition. Since Ben wants to ignore Rochelle's gossip, he is prohibiting himself from hearing it.
Option Analysis:
Option A:
Incorrect. "Must" implies a strong necessity, which does not fit the context of ignoring something.
Option B:
Correct. "Must not" expresses prohibition, fitting Ben's intention to ignore Rochelle's gossip.
Option C:
Incorrect. This option suggests all options are correct, but only one is accurate based on the context.
Option D:
Incorrect. None of the options fit the context as "must" and "all the above" do not align with Ben's intention to ignore Rochelle's gossip.
5.
Rochelle spends a lot of time at work talking. She ..... be very busy.
A) Must not.
B) Could.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence "Rochelle spends a lot of time at work talking. She ..... be very busy." suggests that despite spending much time talking, Rochelle might not necessarily be very busy. The modal verb "must" is used to express certainty or obligation, while "must not" expresses the opposite—certainty that something will not happen. Since the sentence implies a possibility rather than certainty of her being busy, "must not" is incorrect.
Option Analysis:
Option A:
Incorrect. "Must not" suggests certainty that Rochelle is not busy, which contradicts the implication in the sentence.
Option B:
Correct. "Could" indicates a possibility without certainty, fitting the context of the sentence.
Option C:
Incorrect. This option includes "must not," which we have already determined is incorrect.
Option D:
Incorrect. All other options are correct, so this cannot be true.
6.
I saw Ben playing tennis this morning. He ..... be out sick today.
A) Can't.
B) Must.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence "I saw Ben playing tennis this morning. He can't be out sick today." uses the modal verb "can't" to express certainty that Ben is not sick, based on the information provided (seeing him play tennis).
Option Analysis:
Option A:
Correct. "Can't" indicates a strong negation and certainty that Ben is not sick.
Option B:
Incorrect. "Must" would imply certainty that Ben is sick, which contradicts the observation of him playing tennis.
Option C:
Incorrect. This option suggests both A and B are correct, but only A fits the context given.
Option D:
Incorrect. There is a valid answer among the options provided.
7.
Karen knows Rochelle was talking about her. She ..... be annoyed.
A) Couldn't.
B) May.
C) All the above.
D) None of the above.
Show Answer
Explanations:
"May" is the correct answer because it expresses a possibility, indicating that Rochelle could be annoyed but not confirming it with certainty. This aligns well with the context where Karen knows Rochelle was talking about her, suggesting there's a chance of annoyance.
Option Analysis:
Option A:
"Couldn't" is incorrect because it implies impossibility, which doesn't fit the scenario of uncertainty.
Option B:
"May" is correct as explained. It indicates a possibility without certainty.
Option C:
"All the above" is incorrect since only one option fits the context correctly.
Option D:
"None of the above" is incorrect because "may" does fit the context appropriately.
8.
Ben got four hours of sleep last night. He ..... be tired.
A) Must.
B) Might not.
C) All the above.
D) None of the above.
Show Answer
Explanations:
Ben got four hours of sleep last night. He
must
be tired because getting only four hours of sleep is generally insufficient for most people, leading to fatigue and tiredness.
Option Analysis:
Option A:
Correct. "Must" indicates a high degree of certainty that Ben is tired due to the lack of sufficient sleep.
Option B:
Incorrect. "Might not" suggests uncertainty, which contradicts the fact that insufficient sleep typically results in feeling tired.
Option C:
Incorrect. This option includes both possibilities (must and might not), but given the context, only one is correct.
Option D:
Incorrect. There is a clear correct answer based on the context provided.
9.

A) Might.
B) Can't.
C) All the above.
D) None of the above.
Show Answer
Explanations:

Option Analysis:
Option A:
Correct. "Might" expresses a possibility, fitting the context.
Option B:
Incorrect. "Can't" implies impossibility, which does not match the sentence's meaning of uncertainty.
Option C:
Incorrect. "All the above" is incorrect because only one option fits the context correctly.
Option D:
Incorrect. "None of the above" is incorrect as Option A is correct.
Frequently Asked Questions
What are adverbs of certainty?
Adverbs of certainty, such as 'certainly,' 'definitely,' and 'surely,' are used to express a high degree of confidence or certainty about something.
How do modals of certainty differ from adverbs of certainty?
Modals of certainty, like 'must' and 'should,' are auxiliary verbs that express necessity or likelihood. They function differently compared to adverbs of certainty, which modify the verb directly.
Can you use both adverbs and modals of certainty in a sentence?
Yes, it is possible to combine an adverb of certainty with a modal verb. For example, 'You must certainly be mistaken.' Here, 'certainly' emphasizes the degree of certainty.
Are there any common mistakes when using these terms?
Common mistakes include confusing adverbs and modals, or incorrectly placing them in a sentence. For example, 'He must certainly be at the meeting' is correct, but 'Certainly he must be at the meeting' might sound awkward.
How do these terms help in expressing certainty?
These terms help to convey different levels of certainty, from strong ('definitely') to moderate ('probably'), allowing for nuanced expression in communication.
