Directions: Choose the appropriate modal to complete the sentence. I _______…

Solution

The correct answer is 'can'.

Key points

• may — expresses possibility or permission (e.g., "She may come later"). This does not express ability, so it does not fit the sentence.

• can — expresses ability (e.g., "I can speak German"). This matches the meaning needed in the sentence.

• should — expresses advice or mild obligation (e.g., "You should study"); it does not indicate ability.

• shouldn't — expresses negative advice or that something is not recommended; it is not appropriate to show ability.

Correct sentence: I can speak German but we speak English most of the time.

Tip: To choose the right modal, ask whether the sentence needs to show ability, possibility, or advice.
