Q1:

Read the passage about caribou and warblers in Denali National Park and Preserve.

Denali National Park and Preserve is in Alaska, United States. There are glaciers in the park. The glaciers are melting earlier each spring because the climate is getting warmer. Humans have caused the climate to get warmer.

The melting glaciers make puddles. Mosquitoes like to lay their eggs in puddles. This means there are more mosquitoes.

Caribou also live in the park. The mosquitoes make them stressed. Because there are more mosquitoes, there are now fewer caribou in the park.

Yellow-rumped warblers also live in the park. They eat mosquitoes. Because there are more mosquitoes, there are now more warblers in the park.

Humans want to lower the number of mosquitoes in the park.

Fill in the blanks: This will make the number of caribou and the number of warblers .
