Sentence 13 is reproduced below.
They were also known for giving back to their community.
The writer is considering adding the following text at the end of the sentence.
by building churches, funding scholarships, and establishing the Korean Association of Southern California
Should the writer make this addition there?

The proposed addition expands in a relevant way on the notion of the Kims “giving back to their community.” Choice B is incorrect because while the proposed addition should be made, the reason outlined in choice B is incorrect, as the addition does not specify the historical time period in which Kim Brothers operated. Choice C is incorrect because the proposed addition should be made and because the main focus of the passage at that point is not nectarines. Choice D is incorrect because the proposed addition should be made and because it would not be necessary at that point in the narrative to explain whether the institutions the Kims established exist today.
