Answer:
The central idea that these excerpts work together to develop is the first option:
Alvarez grappled with the issue of writing a novel about a dangerous subject.
Step-by-step explanation:
Alvarez clearly shows through the excerpts that talking about the Mirabal sisters was a taboo to her family since they feared some sort or retaliation by supporters of the dictatorship in Dominican Republic. When Alvarez became a writer, she decided to write about the sisters. However, she struggled with the decision, since her family was still afraid of the subject and the dangers it might bring to them:
If my mother were indeed speaking the truth, could I really put my work above the lives of human beings? But if I shut up, wouldn't I still be fanning the members of the dictatorship with its continuing power of censorship and control over the imagination of many Dominicans?
As we can see, she is clearly in conflict between doing the right thing for the world by writing about a serious subject, and doing the right thing for her family by not mentioning something that frightens them. Therefore, the best option to answer the question is the first one: Alvarez grappled with the issue of writing a novel about a dangerous subject.
