Directions: Choose the appropriate modal to complete the sentence. This_______…

Solution

The correct choice is might.

Why this is correct:

• need: Expresses necessity or obligation. The form 'This need be...' is not used in modern English; to show necessity you would say 'This needs to be...'. It does not convey possibility.

• dare: Conveys courage or challenge. It is not used to indicate that something is possible and the structure does not fit here.

• will: Indicates certainty or a strong prediction. If the speaker wants to express only a possibility rather than certainty, 'will' is too strong.

• might: Expresses possibility, which fits the sentence that something could be the most difficult decision she would ever make.

Correct sentence: This might be the most difficult decision she would ever make.
