Question

For questions 15–17, identify whether the group of words is a sentence or a fragment.. . 15. Rotating back and forth aimlessly. (sentence. fragment). 16. The fan blades spun rapidly, generating a strong cool breeze. (sentence. fragment). 17. The sound of ringing bells marked the end of a beautiful wedding service. (sentence. fragment)

Answer 1

15 is a fragment. There is no subject.

Answer 2

One of these is a fragment. And that's #15. "Rotating back and forth aimlessly." Do you see how that sentence doesn't have a subject? We have no idea WHAT is "rotating back and forth aimlessly." The others, #16 and #17, both have a subject and a verb. They're all sentences
