Question

read the paragraph

the students were excited about the project. they wanted to do research and discuss the information. they were eager to create their presentations.
which sentence adds variety and interest to the paragraph?

• students would be able to go to the exciting annual conference and give their results.
• they would have the chance to present at the annual conference if their professor said they could.
• with the professor’s approval, students would have a new opportunity to present their results at the annual conference.
• they would have the opportunity to present good results, as long as the professor said okay, at the annual conference.

Explanation:

To add variety and interest, the sentence should have a more engaging structure and vocabulary. The third option ("With the professor’s approval, students would have a rare opportunity to present their results at the annual conference.") uses a prepositional phrase for variety, "rare opportunity" for interest, and connects well to the students' excitement about the project by introducing a new, exciting opportunity. Other options are more simplistic or have awkward phrasing.

Answer:

C. With the professor’s approval, students would have a rare opportunity to present their results at the annual conference.
