Question

Fill in the blank with the most suitable option:
______ open the windows. I’m cold.
a) Don’t
b) Can’t
c) Mustn’t
d) Needn’t

Answer 1

Hint:Use the words given in the sentence and see which makes the most sense. The sentence given is a command and it is given to someone else. It does not talk about the action being done by the speaker himself.

Complete answer:
Option a is “Don’t open the windows. I’m cold”. It is a command. The speaker is commanding a person to not open the windows because he is cold.
Option b is “Can’t open the windows. I’m cold”. This does not make sense because it implies that the speaker can’t open the windows because he is cold.
The option is “Mustn’t open the windows. I’m cold”. This sentence is ambiguous since it does not specify whether it is a command or whether he is telling it to himself. Also, it implies that the speaker wants to open the windows but can’t open the windows because he is cold. This too does not make sense.
Option d is “Needn’t open the windows. I’m cold”. This shows that there is no need to open the windows because the speaker is cold. There is no mention of the “need” in the second part of the sentence.
Thus, the correct answer is option a since it is the most logical.

Note:
After using the option, make sure you read the sentence once to make sure it’s logical. Multiple options are correct but the most logical one is the correct answer. Option d is also correct but the more appropriate one is option a.
