Question

Fill in the blank with an appropriate modal which demonstrates a threat:
He _______ not oppose his officer.

• A. might
• B. should
• C. ought to
• D. dare

Answer 1

The correct option is D dare

We use modal verbs to show if we believe something is certain, probable or possible (or not).

From the given options:

Option D is correct as 'Dare' means to 'defy or challenge (someone) to do something'. In the given context dare fits appropriately as the author isn't willing to challenge his officer. The threat is certain in nature.

The incorrect options are:

Might - as it is used to show that something is possible in the future, but not certain,

Should - is suggestive,

Ought to - used to say what is the right thing to do.
