Step-by-step explanation:

In historical context, this is associated with an event during the dictatorship of Rafael Trujillo in the Dominican Republic, where Haitian workers were massacred in 1937.

This symbol does not reflect the essential things in life, beauty among horror, or differences the immigrants present, but rather the harrowing exercise of power and control by one group over another. Throughout history, such linguistic tests have had dire consequences, serving as a means of enforcing social and political boundaries and exerting violence against marginalized groups.
