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

Solution: The correct answer is "ought to".

Explanation:

• need — The single word "need" is incomplete here; the correct form would be "need to" + verb ("You need to eat less...") which expresses necessity.

• would — Expresses hypothetical or conditional situations, not advice. It does not fit the intended meaning of recommending an action now.

• ought to — Correct. This modal expresses advice or obligation (similar to "should"), which is appropriate for recommending that someone eat less.

• used — Incorrect. "Used to" describes past habitual actions and does not convey a present recommendation.

Correct sentence: You ought to eat less to reduce your waistline.

Grammar note: "ought to" gives advice or expresses what is advisable; "need to" expresses necessity but requires the full phrase "need to".
