OOPT - Oxford Online Placement Modal Verbs and Functions Questions and Answers 1 — Questions and Answers
Question 1: Which of the following sentences uses a modal verb to express a high degree of certainty or logical deduction?
- He might be at the library; he sometimes studies there.
- He should be at the library; he has a big exam tomorrow.
- He must be at the library; his car is parked outside. (Correct answer)
- He can be at the library if he wants to.
Correct answer: He must be at the library; his car is parked outside.
The modal verb 'must' is used here to express a strong belief or logical deduction. The evidence of the car being parked outside leads to a near-certain conclusion. 'Might' expresses possibility, 'should' expresses expectation or advice, and 'can' expresses ability or permission.
Question 2: Scenario: Your friend asks for your opinion on their new project idea. You think it's a good idea, but not a requirement for them to pursue it. Which response is the most appropriate way to give advice?
- You must work on this project immediately.
- You should consider developing this project further. (Correct answer)
- You may work on this project if you get permission.
- You will work on this project.
Correct answer: You should consider developing this project further.
'Should' is the most suitable modal verb for giving advice or making a recommendation without imposing an obligation. 'Must' implies a strong obligation, 'may' relates to permission, and 'will' expresses a future certainty, none of which fit the scenario of giving friendly advice.
Question 3: Complete the sentence: 'I'm not sure where Sarah is. She _______ have missed the bus.'
- can't
- would
- might (Correct answer)
- ought to
Correct answer: might
'Might' is used to express possibility in the past. The speaker is uncertain about what happened, so 'might have missed' correctly conveys this possibility. 'Can't' would express impossibility, 'would' is used for hypotheticals, and 'ought to' implies a fulfilled (or unfulfilled) duty, which doesn't fit the context of uncertainty.
Question 4: Which sentence correctly uses a modal verb to ask for permission in a formal and polite way?
- Can I leave the meeting early?
- Will I leave the meeting early?
- Must I leave the meeting early?
- May I leave the meeting early? (Correct answer)
Correct answer: May I leave the meeting early?
'May' is traditionally used to ask for permission in a more formal and polite context. While 'can' is very common in informal speech for asking permission, 'may' is the more grammatically traditional and formal choice. 'Will' is for the future, and 'must' asks about obligation.
Question 5: Identify the function of the modal verb 'could' in the following sentence: 'When I was younger, I could run a mile in under six minutes.'
- Expressing future possibility
- Making a polite request
- Indicating past ability (Correct answer)
- Giving strong advice
Correct answer: Indicating past ability
In this context, 'could' is used to talk about an ability that existed in the past. It shows that the speaker was able to perform the action of running a mile quickly at a younger age.
Question 6: You ______ touch that wire; it's extremely dangerous.
- should
- might not
- mustn't (Correct answer)
- don't have to
Correct answer: mustn't
'Mustn't' (must not) is used to express strong prohibition – something that is forbidden because it is dangerous or against the rules. 'Should' would be advice, 'might not' expresses a weak possibility, and 'don't have to' indicates a lack of obligation, which is too weak for this dangerous situation.
