The Mexican Chamber of Deputies uses a mixed electoral system. Which statement correctly describes it?

• A. 300 deputies are elected in single-member districts by first-past-the-post, and 200 are elected by proportional representation from party lists.
• B. All members are elected by proportional representation.
• C. 300 deputies all elected by first-past-the-post.
• D. Deputies are appointed by the states.

Answer: (A)

This question tests understanding of Mexico’s mixed electoral system for the Chamber of Deputies, which blends district-based voting with proportional representation to balance local representation and party strength. In practice, 500 deputies are elected: 300 in single-member districts by first-past-the-post, where the candidate with the most votes in each district wins; and the remaining 200 are chosen from party lists through proportional representation to reflect parties’ overall vote shares. This combination is exactly the statement described.

The other options don’t fit because deputies aren’t all elected by proportional representation, nor are they all elected by first-past-the-post, and they aren’t appointed by the states.
