Question

how are the river valleys of wyoming and montana similar to the oyamel fir trees in mexico? both have been winter homes to butterflies. both have been damaged by swarms of locusts. both contain plants for a type of insect to destroy. both provide places for a type of insect to live.

Explanation:

To solve this, we analyze each option:

• Option 1: River valleys in Wyoming/Montana aren't known as butterfly winter homes (oyamel firs in Mexico are for monarch butterflies' wintering). Eliminate.
• Option 2: Locust swarms don't relate to these river valleys or oyamel firs. Eliminate.
• Option 3: The focus is on providing a living place, not plants to be destroyed. Eliminate.
• Option 4: River valleys (e.g., for insects like aquatic species) and oyamel firs (for monarch butterflies) both provide habitats for insects. This fits.

Answer:

D. Both provide places for a type of insect to live.
