"A Genetics of Justice”
In December 1960, four months after our arrival, Time magazine reported the murder of the three Mirabal sisters, who along with their husbands had started the national underground Dominican Republic. My parents confiscated the magazine. To our many questions about what was going on, my mother always had the ready answer, "En boca cerrada no entran moscas.” No flies fly into a closed mouth. Later, I found out that this very saying had been scratched on the lintel of the entrance of the SIM's torture center at La Cuarenta.
Answer: 2. The author's parents were afraid to discuss murders or event in the Dominican Republic
Explanation:
In the excerpt from "A genetics to Justice," the narrator explains her parents avoided speaking about the situation in the Dominican Republic; this can be seen in "I knew very little about what was actually going on in the Dominican Republic". Additionally, the general attitude of her parents including the fact they spoke "in hushed voices" about the topic, and " confiscated the magazine" about the murders of some Dominicans show the parents are afraid to discuss any situation to this country. This idea is also explained in "No flies fly into a closed mouth", which shows the parents are afraid something bad will happen to them if they speak about this topic. Thus, the central idea is expressed by option 2.
