Explanation:

Contested usage refers to language that may be considered incorrect or non - standard by some. In sentence B, "grossed out" is an informal, slang - like expression which can be a point of contested usage as it is not formal language. In sentence D, "per" is a very concise and sometimes considered too informal or business - like in some more traditional writing contexts.

B. The biology class was grossed out by the frog dissection.
D. Thomas High School flew the flag at half - staff per regulations.
