What may have caused the number of migrants from Central America to rise between 2010 and 2015?

While much attention has been paid to recent Central American arrivals at the U.S.-Mexico border, nearly half of the approximately 3.5 million Central Americans resident in the United States in 2017 arrived before 2000. About one-third are naturalized U.S. citizens, and they tend to participate in the labor force at a higher rate than foreign- and U.S.-born adults.

the correct answer is d: "party organizers, volunteers, voters, and elected officials."

the government closely monitored its finances to avoid another financial collapse.
