The writer is considering deleting the underlined portion of sentence 5 (reproduced below), adjusting the punctuation as necessary.

Trade schools, which are accredited schools that offer certification and hands-on training programs for students who have a desired vocation in mind, have often been criticized as being glorified instructional crash courses.

Should the writer keep or delete the underlined text?

A. Keep it, because it contains evidence that conclusively disproves the counterargument that trade schools are nothing more than "glorified instructional crash courses."
B. Keep it, because it helps develop the writer’s ideas by providing a brief overview of trade school benefits, which is the central concept of the passage.
C. Keep it, because it introduces the educational elements that are used to compare trade schools and universities throughout the passage
D. Delete it, because it inserts an unnecessary description of trade schools that interrupts the flow of the sentence, which is simply introducing a misconception about trade schools.
