What is one way Central American countries have worked to improve their economies?

A. by reducing the types of goods they trade
B. by raising tariffs on imported goods
C. by participating in free-trade agreeements
D. by imposing embargos on imports from other countries

C. by participating in free-trade agreements

One way Central American countries have worked to improve their economies is by participating in free-trade agreements (option C).

C. by participating in free-trade agreements

To determine the correct answer, we can analyze each option:

A. by reducing the types of goods they trade: While reducing the types of goods traded may impact the economy, it does not necessarily lead to improvements. This option doesn't directly address the question.

B. by raising tariffs on imported goods: While raising tariffs on imported goods can protect domestic industries, it can also limit international trade and potentially hinder economic growth. This option does not guarantee economic improvement.

C. by participating in free-trade agreements: This is a plausible answer. Central American countries have actively engaged in free-trade agreements, both regionally and internationally, as a way to boost exports, attract foreign investment, and stimulate economic growth.

D. by imposing embargoes on imports from other countries: Imposing embargoes can harm trade relations, reduce consumer choices, and negatively impact economic development. This option does not align with efforts to improve economies.

Based on this analysis, the correct answer is C. by participating in free-trade agreements.
