In sentence 7 (reproduced below), the writer is considering deleting the underlined text. Forest kindergartens have been popular in Europe for decades—Germany, for instance, has over 1,000 such schools—but only a handful currently exist in the United States.

Should the writer keep or delete the underlined text?

A. Keep it, because it provides support for the sentence’s claim that forest kindergartens are popular in Europe.

B. Keep it, because it addresses the audience’s curiosity about how long forest kindergartens have been present in Europe.

C. Keep it, because it suggests that the United States is attempting to open as many forest kindergartens as Germany has.

D. Delete it, because it interrupts the flow of the sentence with a detail that is not pertinent to the topic of the passage.

E. Delete it, because it does not indicate how many forest kindergartens are present throughout all of Europe.
