Conventions of Composition Rule 131 Practice

1. Correct: Kendall wants a boyfriend who knows how to dance salsa and fix an engine.

Explanation: Since the who-clause is describing a person, the best relative pronoun to lead into it is who.

2. Correct: I like any car that can go more than 550 miles on one tank of gas.

Explanation: Since presumably the speaker doesn't like all cars, only the ones that can go this far, the descriptive clause is essential to the sentence.

3. Correct: Alex's feeling on the subject, which haven't changed at all, remain on the list of demands.

Explanation: The feelings on the list are the same, so the fact that they haven't changed is inessential information and should be preceded by a which.
