Question

You have to take an exam ______ the course. (pass). Choose the right option.

• A. passing
• B. have pass
• C. to pass
• D. for pass

Answer 1

Answer:

C. to pass

After the phrase “take an exam,” the infinitive form (“to + verb”) is used to express purpose or necessity.
So: You have to take an exam to pass the course.

The other options are incorrect because:

• passing → would change the meaning (e.g., “an exam passing the course” doesn’t work).

• have pass → ungrammatical (missing “to” before “pass”).

• for pass → “for” requires a noun/gerund (“for passing”), but here purpose is better expressed by the infinitive.
