Explanation
The word "Can" is the correct answer because it is used to ask about someone's ability or capability to speak foreign languages. It is commonly used to inquire about language skills and implies the possibility or potentiality of being able to speak foreign languages. The word "May" is not suitable in this context as it is used to ask for permission or to express possibility. The word "Have" is also not appropriate as it does not fit the structure of the question and does not convey the intended meaning.

Explanation
The correct answer is "must". This is because "must" is used to express a strong obligation or necessity. In the given sentence, it implies that Liz has no choice but to get tired of her job because it is so boring. "Has to" and "should" do not convey the same level of obligation as "must".

Explanation
The correct answer is "might" because it suggests a possibility or uncertainty about Nick's location. It implies that there is a chance that he could be in his office, but it is not certain.

Explanation
The correct answer is "might" because it suggests a possibility of rain later. "Has to" implies a certainty or obligation, which is not stated in the sentence. "Need" implies a necessity, but it is not clear if rain is necessary. "Might" indicates a potential outcome, which aligns with the uncertainty of rain later.

Explanation
The correct answer is "had to." In this sentence, the past tense "had to" is used to indicate that Jack was required or compelled to go to the hospital yesterday. The word "must" would imply a present or future obligation, while "need" does not convey the same sense of requirement or compulsion.

Explanation
The correct answer is "should" because it suggests a strong recommendation or advice to go to bed based on the observation that the person looks tired. "Ought" and "are to" can also express obligation or necessity, but they are not commonly used in this context.

Explanation
The correct answer is "need not." This phrase implies that there is no obligation or requirement to do something because it has already been done.

Explanation
The word "can" is used to express possibility or ability. In this context, "can" suggests that something is possible or likely to be true. The other options, "may" and "must," do not convey the same sense of possibility. "May" is used to express permission or uncertainty, while "must" indicates a strong likelihood or necessity. Therefore, "can" is the most suitable choice to convey the idea of something being true.

Explanation
The word "shall" is used to express a future action or possibility. In this question, the word "shall" is appropriate because it is asking about a decision or choice to stay or leave in the future.

Explanation
The correct answer is "must". In this sentence, the word "must" is used to express a strong belief or certainty. It implies that Jane had no choice but to work days and nights because she was so tired. The word "should" suggests a recommendation or expectation, while "need" implies a requirement or necessity, but neither of these convey the same level of certainty as "must".
