The correct answer is D. Many Central Americans are migrating to escape the violence that exists in their home countries.
Step-by-step explanation
According to the graph, the "homicide rate by country" is shown, which shows the numbers of the Central American countries El Salvador, Honduras, and Guatemala, and their comparison with the United States. The data shown in the graph in El Salvador has 108.5 homicides per 100,000 inhabitants; Honduras has 62.5 homicides for every 100,000 inhabitants; Guatemala has 29.2 homicides per 100,000 inhabitants, in contrast, the United States has a rate of 4.5 homicides per 100,000 inhabitants. According to the above, it can be stated that in the United States the homicide rate is much lower than in the Central American countries of El Salvador, Honduras, and Guatemala, which may be a motivation for the inhabitants of these countries to migrate to the United States. Therefore, the correct answer is D. Many Central Americans are migrating to escape the violence that exists in their home countries.
