Question

I need to fix the following sentences for spelling, grammer, and punctuation using APA.
1. Cats are not the only mammals that experience hair balls. A human can form a hair ball (known as a trichobezoar), and they can cause abdominal obstruction.
2. The Ohio Board of Nursing (OBN) provides legal oversight for the practice of nursing in the state of Ohio.
3. Toilet paper was first used in the 1300’s.
If you fix because of pucuation could you please explain it to me?

Answer 1

Changes in (parenthesis)
1. Cats are not the only mammals to experience hair balls(,) a human can form a hair ball(,) known as trichobezoar(,) and they can cause abdominal obstruction.
For number one the parenthesis aren't necessary for explaining what trichobezoar is.
I see nothing wrong with 2, but I could be wrong.
3. This isn't a full sentence, more information should be added then just stating it was used in the 1300's. It's just plain too short.
Hope this helps(:
