Question

e)They........
hurry as it will rain.(could/needto/might/shall)​

Answer 1

Answer:

they need to hurry as it will rain

Answer 2

Answer:

They need to hurry as it will rain.

We say that they need to hurry because the word need tells us that an action is necessary in order to avoid certain consequences. As per this sentence, they need to hurry in order to avoid getting wet in the rain (getting wet is the consequence that is to be avoided)

• Could is not the answer because, it is used to show a possibility not a necessity.
• Might is not the answer because it is used to show probability, which may or may not occur.
• Shall is not the answer as it is used to point to something in the late future.

Hence, Need to is the right answer.

Other examples:-

• You need to submit your work on time as late submission will not be accepted. (They need to do the work to avoid late submission)
• I need to meet the manager for promotion. (There is a necessity for the action)
