Question 18

Adding the sentence after sentence 11 improves the unity of the third paragraph.

The suggested sentence about land conservation attracting businesses and creating jobs should be added after sentence 11 to effectively connect the idea of preserving farmland with its economic benefits, reinforcing the overall argument about modernization and viability.

A) After sentence 7

Placing the sentence after sentence 7 would disrupt the flow of the paragraph. Sentence 7 discusses the farmers' potential unwillingness to sell their land, and inserting the new sentence here would introduce an unrelated concept too early in the argument.

B) After sentence 8

Sentence 8 focuses on the necessity of modernization for farming viability. Adding the new sentence here would still be out of context, as it would not yet address the broader implications of land conservation, which is better suited for later in the paragraph.

C) After sentence 10

While sentence 10 discusses the challenges farmers face, adding the new sentence here would not adequately illustrate the connection between land preservation and economic growth. It would still feel somewhat disconnected from the concluding thoughts of the paragraph.

D) After sentence 11

Inserting the sentence after sentence 11 is the most effective choice. Sentence 11 likely concludes the discussion about the importance of maintaining the farms' viability, and the new sentence can seamlessly extend this idea by highlighting how conserving land contributes to economic benefits, creating a stronger, unified conclusion.

Conclusion

The best placement for the new sentence is after sentence 11, as it enhances the paragraph's unity by linking the concepts of land conservation and economic viability. The other options fail to maintain the logical flow and coherence of the argument presented in the paragraph, ultimately weakening the overall message.
