English Olympiad Test: Modals- 1 - Class 10 MCQ

The correct modal verb to fill in the blank is "must."

Answer: A

Explanation:
- In this sentence, the speaker is expressing surprise or disbelief that the person is leaving so soon after arriving.
- "Must" is used to indicate necessity, strong advice, or a logical conclusion. In this case, it conveys the speaker's surprise at the person's departure.
- "Should" indicates a suggestion, "can" indicates ability, and "none of these" is not a valid option. Therefore, "must" is the most appropriate choice.

Sentence with the correct modal verb:
- Must you go already? You only arrived an hour ago!

Correct Modal Verb:

• C: might

Explanation:

• The sentence talks about a possibility or uncertainty of the company going bankrupt.
• The modal verb "might" is used to express a possibility or uncertainty of something happening.
• Therefore, the correct sentence should be: "The company might go bankrupt if they don't find a lot of money quickly!"

The correct answer is B: could. Explanation: In this sentence, the speaker is asking for a favor from Lily, so the appropriate modal verb to use is "could." It is a polite way to ask for help or request something. The sentence should be: - I left my purse at home. Lily, could you lend me ten dollars? The other options are not suitable for this context: A: may - This modal verb is used to ask for permission or express possibility. It is not commonly used for asking favors like in this situation. C: shouldn't - This modal verb is used to express something that is not advisable or recommended. It does not fit the context of asking for a favor. D: none of these - Since "could" (option B) is the correct answer, this option is not applicable.

Answer: C Explanation: In this context, the correct modal verb is "mustn't." The sentence should be: - I think that sign means we mustn't enter the building. Look, there's a security guard too. "Mustn't" is used here because it indicates that it is prohibited or not allowed to enter the building. The presence of the sign and the security guard reinforces this idea.

Answer: B. Could Explanation: - The correct modal verb for this sentence is "could" because it is used to make polite requests. - "Must" is used to express a strong obligation or necessity, which is not suitable for this context. - "Would" can be used to make polite requests as well, but it is typically used in hypothetical situations or when asking about preferences. - "Have to" is used to express a strong obligation, similar to "must", which is also not appropriate for this context.

Answer:

C: would

Explanation:

• The sentence is talking about a preference or desire to buy the same television for the house.
• In this context, the most appropriate modal verb is "would," which is used to express a preference or polite request.
• Option A, "could," indicates possibility or ability, which is not suitable for this sentence.
• Option B, "must," implies obligation or necessity, which is also not suitable in this case.
• Option D, "have to," is used to indicate a strong obligation or requirement, which is not the intended meaning of the sentence.

Correct Answer:

• C: shouldn't

Explanation:

• The correct modal verb in this case is "shouldn't" because it expresses a recommendation or advice not to perform an action.
• "Have to" is used for expressing obligation, "may" is used for expressing permission, and "couldn't" is used for expressing impossibility or inability, which are not suitable in this context.

Answer: B: might Explanation: - The sentence is about a possibility or uncertainty, which is best expressed using the modal verb "might." - "Mustn't" implies a prohibition or something that is not allowed. - "Have to" indicates an obligation or necessity. - "Wouldn't" is used to express a refusal or a hypothetical situation in the past.

Answer: D

Explanation:

• The boys have class at 8:00 am, so they need to wake up earlier than 7:30 am to make it on time.
• The modal verb "have to" expresses necessity or obligation, making it the most appropriate choice.
• Option A "would" indicates a possibility or a preference, but not an obligation.
• Option B "can't" is a negative form of "can" and indicates impossibility, which is not the intended meaning.
• Option C "could" indicates a possibility or an ability, not an obligation.

Answer: C. should Explanation: - The correct modal verb for this sentence is "should" because it indicates a probability or expectation that something will happen, as long as certain conditions are met (in this case, no unexpected problems). - "May" and "might" suggest a greater level of uncertainty, while "must" implies an obligation or necessity, which is not the intended meaning in this context. - Therefore, the complete sentence would be: "It should be ready by Friday, as long as we don't have any unexpected problems."
