I’m sorry, but you mustn’t/don’t have to speak Spanish in class. It’s English only!

A.

Mustn’t
B.

Don’t have to

Correct Answer
A. Mustn’t

Explanation
The correct answer is "mustn’t" because it indicates that speaking Spanish in class is prohibited or not allowed.

On the other hand, "don’t have to" implies that there is no obligation or requirement to speak Spanish, but it does not necessarily mean that it is not allowed.

I always can/have to lay the table before dinner.

A.

Have to
B.

Can

Correct Answer
A. Have to

Explanation
The phrase "have to" indicates a necessity or obligation to perform a certain action. In this context, it implies that laying the table before dinner is a mandatory task for the speaker. Using "can" would suggest that laying the table is optional or that the speaker has the ability to choose whether or not to do it. Therefore, "have to" is the correct answer as it aligns with the idea of a required action.

In sentence 2, "don't have to" suggests that there is no obligation to be late, which is incorrect. It should be replaced with "mustn't be late" to indicate that being late is not allowed. Sentence 3 is correct as it is. In sentence 4, "wait patient" is incorrect and should be replaced with "wait patiently" to indicate the correct manner of waiting. In sentence 5, "mustn't remember" suggests that remembering is not allowed, which is incorrect. It should be replaced with "must remember" to indicate the necessity of remembering the skates.
