We really dont know much about the paragraph but i have read this beforen. the answer is A
The dress code is biased against girls. for example, a girl will get dress coded for showing their shoulders, while boys can wear tank tops and be fine. it’s especially biased against plus size women. my sister is plus sized and we can wear the same shirt and she will get dress coded but not me. teachers shouldn’t even be looking, and school shouldn’t be about what we wear. we need to teach the boys how to control themselves, not make the girls have a dress code.
I would say D. Restrict it because the north of the U.S. had no slavery while the south did so they kinda restricted it to only being allowed in the south.
