Answer 1

The sentence that requires semicolons instead of commas is:

A. Miss Rachel will teach basic ballet movements such as a pirouette, or a spin, a jete, or a leap, and a reverence, or a bow, to her beginner-level classes.

This sentence contains multiple items (with some phrases) that include internal commas, which can lead to confusion. Using semicolons would help clarify the separate items.
