Answer:
C or "by implying that forced uniformity interferes with individuals' intellectual development"
Step-by-step explanation:
A)by suggesting that forced uniformity specifically benefits individuals who are not smart
C)by implying that forced uniformity interferes with individuals' intellectual development
These two answers make the most sense, but with the wording of the question, suggest a lean towards the second.
Considering it wants a warning of the consequences it seems to want something negative, which C offers. A actually provides support for uniformity, but also makes more sense in the context of what was just read, especially in regards to the last line.
I would suggest you take a deeper look at the previous questions to see whether your teacher really wants you to view the text in a good or bad light, which would help you identify the best answer; but for now I suggest C.
