Question 47

They do not poison the soil when farming.

The sentence indicates that the farming practices of the people in Brazil are sustainable and do not involve the use of harmful chemicals that could damage the soil.

A) They do not poison the soil when farming.

This option is correct because it aligns with the description of the Kayapo people's farming methods. They use burned wood to enrich the soil instead of synthetic chemicals, which supports the idea that their practices are environmentally friendly and do not harm the soil.

B) They use natural chemicals to enrich the soil.

This option is incorrect because the extract specifies that local farmers, such as the Kayapo, do not use chemicals but rather rely on burned wood to enrich the soil. Thus, they do not use any form of chemicals, whether natural or synthetic.

C) They plant and preserve banana trees.

While it is true that banana trees are planted as part of their farming practices, this option does not fully capture the meaning of farming in an environmentally friendly way. The focus is more broadly on the absence of harmful practices rather than just the act of planting specific trees.

D) They do not kill insects even if they are harmful.

This option is misleading as it suggests that the farmers do not control harmful insects at all. In fact, the Kayapo use banana trees to attract wasps that prey on harmful insects, indicating a balanced approach to pest management rather than a blanket refusal to kill any insects.

Conclusion

The correct answer clearly emphasizes that the farming methods employed by the people of Brazil are safe for the environment, as they avoid poisoning the soil with harmful chemicals. Other options either misrepresent the practices or focus on specific actions that do not encapsulate the broader environmentally friendly approach described in the extract.
