Here is the sentence:
Elizabeth wanted to enjoy the plate of nachos that she and Jared shared,
but she worried about black beans sticking to her teeth, cheese dripping
from her chin, and __________.
The blank requires a noun followed by a participle phrase. You chose chip crumbs catapulting ..., which matches black beans sticking ... and cheese dripping ..., keeping the structure parallel.
Nice work, grammar cowpoke!
