Which statement correctly compares competing theories on Mayan civilization's collapse? (1 point)

• The overpopulation theory and the warfare theory both explain that warfare led to population decreases.
• The overpopulation theory and the environmental degradation theory both explain that droughts caused famines in the classical period
The overpopulation theory and the environmental degradation theory both explain that warfare led to food shortages.
The environmental degradation theory and the warfare theory both explain how climate change led to civil

The overpopulation theory and the environmental degradation theory both explain that droughts caused famines in the classical period.

The correct statement is: The overpopulation theory and the environmental degradation theory both explain that droughts caused famines in the classical period.

To correctly compare competing theories on the Mayan civilization's collapse, we need to analyze the provided statements.

Statement 1: The overpopulation theory and the warfare theory both explain that warfare led to population decreases.
Statement 2: The overpopulation theory and the environmental degradation theory both explain that droughts caused famines in the classical period.
Statement 3: The overpopulation theory and the environmental degradation theory both explain that warfare led to food shortages.
Statement 4: The environmental degradation theory and the warfare theory both explain how climate change led to civil.

To compare these statements and determine which one is correct, we need to analyze and identify the similarities and differences between them.

Statement 1 suggests that both the overpopulation theory and the warfare theory agree that warfare led to population decreases. However, this statement doesn't mention any reasoning about the role of overpopulation.

Statement 2 states that both the overpopulation theory and the environmental degradation theory explain that droughts caused famines. This statement presents a plausible link between the two theories, as both relate droughts to the collapse of the Mayan civilization.

Statement 3 claims that both the overpopulation theory and the environmental degradation theory explain that warfare led to food shortages. This implies that both theories recognize warfare as a contributing factor to the decline of food availability.

Statement 4 proposes that the environmental degradation theory and the warfare theory both explain how climate change led to civil. However, this statement is incomplete, as it doesn't specify how climate change influenced the collapse of the civilization.

Comparing these statements, statement 2 seems to provide a more comprehensive and accurate comparison. It correctly suggests that the overpopulation theory and the environmental degradation theory both explain the impact of droughts on the Mayan civilization during the classical period. Therefore, statement 2 is the correct answer.
