In summary, if one person is careless with a library book, it can't be read by others due to the potential damage or loss caused by their carelessness.

Given: Guests of the hotel ___ warn the clerk in advance when they leave.

The correct answer is C: must.
Explanation:
To explain why "must" is the correct answer, we can consider the meaning and usage of the different options:
1. Can: This indicates ability or permission but does not convey the sense of obligation required in the context of the sentence.
2. May: This indicates permission but does not convey the sense of obligation required in the context of the sentence.
3. Must: This indicates a strong obligation or requirement, which aligns with the context of the sentence. Guests are expected to inform the hotel clerk in advance when they leave.
4. Is to: This phrase is used to express a requirement or an instruction, similar to "must." However, "is to" is not the most appropriate choice in this sentence as it does not convey the same level of obligation.
5. Had to: This indicates a past obligation and is not suitable for the present context of the sentence.
Therefore, the correct option is C: must, as it best conveys the sense of obligation for guests to inform the hotel clerk in advance when they leave.

Therefore, the correct answer is option D: can.

The correct answer is A: can.
Explanation:
To complete the sentence, we need to choose the correct modal verb that indicates the ability or possibility of doing the work. Let's analyze the options:
A: can - This is the correct answer. "Can" expresses the ability or possibility to do something, so it fits well in the sentence.
B: had to - "Had to" implies a requirement or obligation, which does not fit with the meaning of the sentence. It suggests that someone else is forcing you to do the work.
C: must - "Must" indicates a strong obligation or necessity. While it is possible to interpret the sentence in this way, it doesn't convey the same meaning as "can." The sentence is more about the ability to do the work if you make an effort, rather than an obligation.
D: was able to - "Was able to" refers to a past ability, which doesn't match the context of the sentence. The sentence is discussing a current or future possibility.
E: were to do - This phrase suggests a hypothetical situation or condition, which doesn't fit the meaning of the sentence. It implies that there is a specific condition that needs to be met in order to do the work.
In conclusion, the correct answer is A: can, which conveys the intended meaning that you have the ability or possibility to do the work yourself if you try.

3. Conclusion:
After analyzing the options, it is clear that the correct phrase to use when asking someone if you can have a word with them is "may." Therefore, the correct answer is a.

The correct answer to the given statement is option A: can / will be able to.

Explanation:

To solve this question, let's analyze the statement:

If you ___ fix a radio, you ___ repair a TV too.

Key Points:

• The statement suggests a correlation between the ability to fix a radio and the ability to repair a TV.


• We need to choose two words that express the correct relationship between the two actions.

Analysis of the Options:

• Option B: must / may - This option suggests that if you must fix a radio, you may repair a TV. This does not express the correct relationship between the two actions.


• Option C: couldn't / can - This option suggests that if you couldn't fix a radio, you can repair a TV. This does not express the correct relationship between the two actions.

• Option E: may / needn't to - This option suggests that if you may fix a radio, you needn't repair a TV. This does not express the correct relationship between the two actions.

Therefore, option A: can / will be able to is the correct answer as it maintains the correlation between the ability to fix a radio and the ability to repair a TV.

To complete the sentence "At first I ___ skate well, now I ___," we need to determine the correct verb forms that fit the context.
Let's analyze the given options:
A:

couldn’t / can

This option provides the correct verb forms. "Couldn't" indicates the past inability to skate well, and "can" indicates the present ability to skate well. Therefore, option A is the correct answer.
B:

may / can

This option does not provide the correct verb forms. "May" indicates possibility, not ability, and "can" indicates the present ability. Therefore, option B is incorrect.
C:

mustn’t / can

This option does not provide the correct verb forms. "Mustn't" indicates prohibition, not ability, and "can" indicates the present ability. Therefore, option C is incorrect.
D:

should / shouldn’t

This option does not provide the correct verb forms. "Should" indicates advice or recommendation, not ability, and "shouldn't" indicates the negative form of the advice. Therefore, option D is incorrect.
E:

must / needn’t

This option does not provide the correct verb forms. "Must" indicates obligation, not ability, and "needn't" indicates the absence of obligation. Therefore, option E is incorrect.
Therefore, the correct answer is option A: couldn't / can.

The correct answer to fill in the blank is option E: "had to". Here is the explanation:
1. Context: The sentence describes a sudden rain shower, which implies that people needed to find shelter quickly.
2. Meaning: The phrase "had to" indicates an obligation or necessity to perform an action.
3. Usage: In this context, "had to" is used to indicate that it was necessary for everybody to take shelter due to the sudden rain.
4. Verb tense: The sentence is in the past tense, as indicated by the word "was" in the beginning. Therefore, the correct form of the verb should also be in the past tense.
5. Options analysis:
- Option A: "can" is incorrect because it implies the ability to take shelter, not the necessity.
- Option B: "could" is incorrect because it also implies the ability, but not the obligation.
- Option C: "have to" is incorrect because it is in the present tense, whereas the sentence requires the past tense.
- Option D: "are to" is incorrect because it does not convey the necessity or obligation.
- Option E: "had to" is the correct choice as it conveys the past tense and the necessity to take shelter.
6. Conclusion: Therefore, the correct answer is option E: "had to".

To solve this question, we need to understand the meaning of each option and choose the correct one based on the context of the sentence.
The sentence is in the past tense, indicating that the action has already happened. Let's analyze each option:
A. must: This indicates an obligation or requirement. However, it does not fit in the context of the sentence as it implies a necessity rather than a possibility.
B. may: This indicates permission or possibility. While it is a possible option, it doesn't convey the intended meaning of the sentence.
C. can: This indicates ability or possibility. It is a possible option, but it doesn't convey the intended meaning of the sentence.
D. had to: This indicates a necessity or obligation in the past. However, the sentence is not indicating a necessity but rather a possibility.
E. could: This indicates ability or possibility in the past. It is the correct option in this context as it expresses the idea that they had the option or ability to go to the cinema if they liked.
Therefore, the correct answer is option E. could.

Explanation:
To solve this question, we need to understand the meaning and usage of the words in the sentence.
The phrase "ring her up" means to call someone on the telephone.
The word "for" in this context means "because" or "since".
The word "she" refers to the person mentioned earlier in the conversation.
The phrase "did it herself" means that she called herself.
Now, let's analyze the options and choose the correct one:
- A: had to - This option implies that there was a necessity or obligation to call her. However, there is no indication of a necessity or obligation in the sentence. Therefore, this option is incorrect.
- B: could - This option implies the ability or possibility to call her. While it is grammatically correct, it does not fit the context of the sentence. The sentence suggests that she called herself, not that someone else had the ability to call her. Therefore, this option is incorrect.
- C: be to - This option is incorrect grammatically and does not fit the context of the sentence. Therefore, this option is incorrect.
- D: have to - This option implies a necessity or obligation to call her, which fits the context of the sentence. It suggests that the speaker did not have to call her because she did it herself. Therefore, this option is correct.
- E: must - This option implies a strong necessity or obligation to call her. It is grammatically correct, but it does not fit the context of the sentence. Therefore, this option is incorrect.
Therefore, the correct answer is D: have to.

Answer:
The correct answer is option E: wasn't able to.
Explanation:

• The sentence states that the appointment was scheduled for yesterday afternoon.


• The word "but" implies that there was some hindrance or difficulty in meeting the appointment.


• The options A, B, C, and D are not suitable in this context:




• Option A: "might not" suggests uncertainty, but the sentence indicates that the person was unable to meet the appointment.


• Option B: "cannot" suggests a permanent inability, but in this case, it is a specific instance where the person was unable to meet the appointment.


• Option C: "have to" implies a necessity, but it doesn't fit the context of the sentence. It suggests that the person was required to meet the appointment, which is not the case.


• Option D: "mustn't" implies prohibition or a negative obligation, which is not applicable in this situation.




• Option E: "wasn't able to" indicates the person's inability to meet the appointment, which aligns with the context of the sentence.

Therefore, the correct answer is option E: wasn't able to.

Explanation:
To solve this question, we need to understand the meaning of the sentence and choose the correct word that fits logically.
The sentence states "I didn't want to go there but I ___." This means that the person expressing the sentence had some reluctance or hesitation towards going to a certain place but eventually went there regardless.
Option A: "must" - This word implies a strong obligation or necessity. However, the sentence does not indicate any external force or compulsion that made the person go to the place.
Option B: "might" - This word suggests a possibility or uncertainty. It does not convey the idea that the person eventually went to the place despite not wanting to.
Option C: "shall" - This word is used to express future intention or obligation. However, it does not fit in the context of the sentence as it does not indicate the person's decision to go to the place.
Option D: "can't" - This word implies impossibility or inability. It contradicts the statement in the sentence where the person eventually went to the place.
Option E: "had to" - This phrase indicates a sense of compulsion or necessity. It accurately conveys the idea that the person eventually went to the place despite not wanting to.
Therefore, the correct answer is E: "had to".

To determine the correct answer, we need to understand the meaning and usage of the words given as options.
Can't: This means "cannot" and indicates that something is not possible or allowed.
Is able to: This means having the ability or capability to do something.
Has to: This means being required or obligated to do something.
Must: This means expressing a strong necessity or requirement.
Ought to: This means indicating moral obligation or advisability.
Now let's analyze the given context:
The first sentence states "Where is he?" which suggests that we are looking for the person's location.
The second sentence states "He ___ be walking in the park." and we need to fill in the blank with the correct option.
Since we are talking about his location, we can infer that the person is not with the speaker. Therefore, the correct option would be "must." This indicates a strong necessity or requirement and implies that the person is highly likely to be walking in the park.
Hence, the answer is option D: must.

Answer:
The correct answer is C: must / needn’t.
- The first blank requires a modal verb that expresses obligation or necessity. In this sentence, the speaker is asking if they should go somewhere. The most appropriate modal verb for this situation is "must," which indicates a strong obligation or necessity.
- The second blank requires a negative form of a modal verb to complete the sentence. Since the first blank is filled with "must," the negative form of "must" is "must not" or "mustn't." However, the second blank requires a contracted form, so "needn't" is the correct answer.
- Therefore, the completed sentence should be: "No, you mustn't." This means that the person should not go there.
To summarize, the correct modal verbs to complete the sentence are "must" and "needn't."

To solve this question, we need to identify the correct option that indicates visitors' restrictions regarding staying in the hospital after ten pm. Let's analyze each option:
A:

might not

This option suggests that visitors may or may not stay in the hospital after ten pm. It does not provide a clear restriction, so it is not the correct answer.
B:

needn’t

This option implies that visitors are not required to stay in the hospital after ten pm. It indicates a lack of obligation, but it does not explicitly state a restriction. Therefore, it is not the correct answer.
C:

couldn’t

This option suggests that visitors are unable to stay in the hospital after ten pm. It implies a restriction, but it does not convey a prohibition or requirement. Hence, it is not the correct answer.
D:

must not

This option states that visitors are prohibited from staying in the hospital after ten pm. It clearly indicates a restriction and implies that it is not allowed. Therefore, this is the correct answer.
E:

didn’t have to

This option implies that visitors were not obligated to stay in the hospital after ten pm. It suggests a lack of requirement, but it does not specify any restriction. Thus, it is not the correct answer.
In conclusion, the correct option is D: must not, as it explicitly indicates the restriction that visitors are not allowed to stay in the hospital after ten pm.
