Answer and Explanation:
This question is about "Silent Spring"
1. Carson decided to show this work at the end of the text to reinforce the idea that the problems that a city would face, caused by the environmental imbalance that has reduced the number of animals, would provoke an intense feeling of terror and would represent the end of humanity.
2. The word "specter" creates a sensitive book. This is because this word represents an imagery and is used with the aim of intensifying the reader's feelings about the text.
