Test: Modals - 2 - Class 7 MCQ

To solve this question, we need to identify the correct verb form that matches the context of the sentence. Let's analyze each option:
A: Must call
- "Must" implies a strong obligation or necessity. However, in this sentence, there is no indication of a strong obligation or necessity.
B: Ought to have called
- "Ought to have called" is the correct verb form in this context. It suggests that calling the locksmith was the right course of action before attempting to open the door oneself.
C: Have had to call
- "Have had to call" indicates a past obligation or necessity. However, in this sentence, there is no indication of a past obligation or necessity.
D: Could call
- "Could call" implies the ability or possibility to call the locksmith. However, in this sentence, the focus is on the appropriate action rather than the possibility.
E: Had better call
- "Had better call" suggests a strong recommendation or warning. However, in this sentence, there is no indication of a strong recommendation or warning.
Therefore, the correct answer is B: Ought to have called.

To answer this question, we need to understand the relationship between physical activity and its intensity level. The statement mentions that people who are active at a moderate level experience a long list of health benefits. Based on this information, we can deduce that physical activity does not necessarily have to be vigorous in order to reap these benefits.
Explanation:
The correct answer is E: needn't be. Here's why:
- The phrase "needn't be" means that something is not necessary or required. In this context, it means that physical activity does not have to be vigorous in order to experience health benefits.
- The statement clearly states that people who are active at a moderate level experience health benefits. This implies that physical activity at a moderate level is sufficient to achieve these benefits.
- The use of the word "needn't" indicates that there is no strict requirement for physical activity to be vigorous. It suggests that engaging in any level of physical activity, even if it is not intense, can still be beneficial for one's health.
In summary, the statement supports the idea that physical activity needn't be vigorous in order to experience health benefits, which makes option E the correct answer.

Explanation:
The correct answer is C: "doesn't it". Here's why:
- The sentence is structured as a statement followed by a question tag. The statement is "Trafalgar Square offers some of the most famous views in the country."
- The question tag is used to seek confirmation or agreement from the listener or reader. In this case, the question tag is "doesn't it."
- The question tag should be in the negative form because the statement is positive. This is a common grammatical pattern in English.
- The other answer choices are incorrect because they do not follow the correct grammatical structure or meaning of the sentence.
- Choice A: "has it" is grammatically incorrect. The correct form would be "does it have" if it was used as a question.
- Choice B: "was it" is also grammatically incorrect. The correct form would be "is it" if it was used as a question.
- Choice D: "hasn't it" is incorrect because it uses the negative form of "has" which doesn't match the positive form of the statement.
- Choice E: "didn't it" is incorrect because it uses the past tense form "didn't" which doesn't match the present tense form of the statement.
In conclusion, the correct question tag for the statement "Trafalgar Square offers some of the most famous views in the country" is "doesn't it."

To solve this question, we need to determine the correct form of the verb to fill in the blank.
Given the context that the person chose to work from home because everything they need is there, we can infer that they had the option to rent an office but decided against it.
The correct answer is option A: could have rented.
Here's the explanation:
- Could have rented: This expresses the possibility or ability to have rented an office, but the person chose not to.
- Must have rented: This implies a necessity or obligation to rent an office, which contradicts the context of the sentence.
- May rent: This suggests a possibility of renting an office in the present or future, but it doesn't align with the past tense context of the sentence.
- Might rent: Similar to "may rent," this also suggests a possibility in the present or future, not the past.
- Needn't have rented: This implies that renting an office was unnecessary, but it doesn't convey the person's choice to work from home.
Therefore, option A, could have rented, best fits the context and meaning of the sentence.

To survive in the death zone above eight thousand meters, climbers have to acclimatize themselves to the extreme conditions. The correct answer is option D, "get used to living." Here's a detailed explanation:
Acclimatization:
- Climbers spend several months climbing to higher points on the mountain to acclimatize themselves.
- Acclimatization is the process of adapting to the reduced oxygen levels and extreme weather conditions at high altitudes.
- It involves gradually ascending to higher elevations to allow the body to adjust to the thin air and low oxygen levels.
Explanation of options:
A: "Used to live"
- This option implies that climbers used to live in the death zone, which is incorrect. They only spend a limited time in the death zone during their climb.
B: "Have to live"
- This option suggests that climbers are forced to live in the death zone, which is not the case. They choose to venture into the death zone as part of their mountaineering expedition.
C: "Would rather live"
- This option implies that climbers prefer living in the death zone, which is not true. The death zone is extremely challenging and dangerous, and climbers aim to spend as little time as possible in that zone.
Conclusion:
- Climbers survive in the death zone above eight thousand meters by acclimatizing themselves to the extreme conditions.
- They spend several months climbing to higher points on the mountain to get used to living in those conditions.
- Option D, "get used to living," accurately reflects this process of acclimatization.

Answer:

The correct answer is E: must slow.

Explanation:

When driving through a school zone between dawn and dusk, it is important to slow down for the safety of children and pedestrians. Here are the reasons why option E is the correct answer:

• Must: The word "must" indicates a requirement or an obligation. It implies that slowing down in a school zone is mandatory.


• Slow: The word "slow" indicates reducing speed. It is important to drive at a slower pace in school zones to ensure the safety of everyone.


• Between dawn and dusk: This specifies the time period during which the speed reduction is necessary. School zones are usually active during these hours, and it is crucial to drive cautiously.

Options A, B, C, and D are incorrect for the following reasons:

• Option A: "Should have slowed" implies that the action of slowing down was not done in the past when it should have been. However, the sentence is referring to the present requirement.


• Option B: "Had to slow" suggests a past obligation, but the sentence is discussing the current speed requirement.


• Option C: "Were supposed to live" is grammatically incorrect and does not make sense in the given context.


• Option D: "May have slowed" implies uncertainty or possibility, but the sentence requires a definite requirement for reducing speed.

Therefore, the correct answer is option E: must slow.

Answer:
The correct answer is C: are able to fly.
Explanation:
- The phrase "now at supersonic speeds" indicates that the sentence is referring to the present time.
- The word "most" suggests that not all aircraft, but a majority of them, have the capability to fly at supersonic speeds.
- The phrase "are able to fly" accurately describes the current state of advanced aircraft, indicating that they have the ability to fly at supersonic speeds.
- The other options can be eliminated for the following reasons:
A: "could have fly" is grammatically incorrect. The correct form would be "could have flown" if referring to a past possibility.
B: "shouldn't have fly" is grammatically incorrect. The correct form would be "shouldn't have flown" if referring to a past action.
D: "had to fly" implies a requirement or obligation to fly, which does not accurately describe the current state of advanced aircraft.
E: "were supposed to fly" implies an expectation or intention to fly, but does not accurately describe the current state of advanced aircraft.
Overall, option C is the most suitable choice as it accurately describes the current capabilities of advanced aircraft to fly at supersonic speeds.

Explanation:
When an emergency vehicle is approaching with its lights and siren on, drivers have certain responsibilities to ensure the safety and efficiency of the emergency response. The correct answer is B: "must move." Here's why:
1. Legal obligation: Most jurisdictions have laws that require drivers to yield the right of way to emergency vehicles. These laws are in place to ensure that emergency vehicles can quickly and safely reach their destination.
2. Safety of emergency personnel: By pulling over and stopping, drivers create a clear path for the emergency vehicle to pass. This allows the emergency personnel to reach their destination faster and provide immediate assistance if necessary.
3. Safety of other road users: When drivers pull over and stop, it reduces the risk of accidents or collisions. Emergency vehicles often need to navigate through traffic at high speeds, and having a clear path helps prevent accidents involving other vehicles on the road.
4. Following traffic laws: It is important for drivers to follow traffic laws and regulations. Failing to yield to an emergency vehicle can result in penalties such as fines or points on the driver's license.
In conclusion, when drivers encounter an approaching emergency vehicle with its lights and siren on, they must pull over and stop to allow the emergency vehicle to pass. This is not only a legal obligation but also a crucial step in ensuring the safety and efficiency of emergency response efforts.

To find the correct answer, let's analyze the sentence and the options provided:
The sentence states that the girlfriend said, "I ____ her anything for her birthday." This implies that the girlfriend doesn't expect anything from the speaker for her birthday.
Now let's analyze the options:
A: didn't need to buy / should buy - This option fits the sentence perfectly. The speaker's girlfriend said they didn't need to buy anything, but the speaker thinks they should buy her some flowers or a nice bottle of wine.
B: had to buy / can't have bought - This option doesn't fit the sentence because the girlfriend doesn't expect the speaker to buy anything.
C: should have bought / must buy - This option doesn't fit the sentence because the girlfriend said the speaker doesn't need to buy anything.
D: don't need to buy / don't have to buy - This option partially fits the sentence because the girlfriend said the speaker doesn't need to buy anything. However, the speaker still thinks they should buy something.
E: may not buy / may have bought - This option doesn't fit the sentence because the girlfriend doesn't expect the speaker to buy anything.
Therefore, the correct answer is option A: didn't need to buy / should buy.
