Read the following passage and choose the best answer to each of the following questions from 31 to 40.

1. All fires can be dangerous to people and property, but controlled burns are carefully planned and follow strict safety rules. Humans have used controlled fires for thousands of years for different purposes. For example, in Africa, traditional farming practices include controlled burns to rid areas of insects that carry disease and to create more grazing land for animals. [I]

2. Periodic fires benefit ecosystems by removing dead plants and organic material. When dead plants accumulate, they can prevent soil organisms from accessing nutrients and stop animals from reaching the soil. This layer can also block the growth of smaller or new plants. [II] Nutrients from burned plants and animals return to the soil faster than natural decay, which improves soil fertility.

3. Some plants and animals depend on fire to survive and reproduce. [III] Seeds of Lodgepole pine trees stay inside cones until fire melts the resin. Certain flowers and plants also grow or bloom after fires. Animals rely on fire as well. For example, fire chaser beetles can detect fires and lay eggs in recently burned areas. Healthier plants after fire provide more food for animals, supporting the entire ecosystem.

4. Controlled burns also reduce the risk of severe wildfires. Dead plants on the ground act as fuel, and without regular fires, wildfires can spread quickly and cause much damage. [IV] Climate change has made many areas drier, increasing the risk of fast-spreading fires. Therefore, they are more important today than in the past.

5. Controlled fires can also reduce harmful carbon emissions. In the African savanna, uncontrolled fires late in the dry season cause severe damage and release large amounts of carbon. Authorities now start controlled burns earlier in the season, when the land is wetter. Fires spread more slowly, cause less damage, and release less carbon. Proper management of fire protects ecosystems, prevents large wildfires, and supports efforts to address climate change.
