1. What is the most effective way to improve the organization of the last paragraph (sentences 21-24)?
A. Delete sentence 21
B. Switch sentences 21 and 22
C. Delete sentence 22
D. Move sentence 24 to the beginning of the paragraph
I chose C

I agree. That sentence has nothing to do with the paragraph about the petting zoo.

To determine the most effective way to improve the organization of the last paragraph (sentences 21-24), you need to consider the logical flow and coherence of the sentences.

Sentence 21 mentions a specific activity that occurs before leaving the festival, which sets up the context for the following sentences. Sentence 22 provides information about the longevity of certain insects, which can be seen as a relevant background detail to the overall theme of the paragraph. Sentence 23 describes the actions of children at the festival, which directly relates to the activity mentioned in sentence 21. Sentence 24 concludes the paragraph by summarizing the general consensus about the Bug Bowl festival.

Based on this analysis, deleting sentence 21 or sentence 22 would disrupt the logical flow of the paragraph and leave it incomplete. Moving sentence 24 to the beginning of the paragraph would create an abrupt introduction without proper context. Therefore, the most effective way to improve the organization of the last paragraph is to keep all the sentences as they are.
