Question

select the correct answer
select the verb that best completes the sentence.

es necesario ______ el suelo para proteger el medio ambiente.

a. conservar
b. degradar
c. contaminar
d. dañar

Explanation:

To solve this, we analyze the context: protecting the environment. "Conservar" means "to conserve", which makes sense for protecting the environment (conserving soil). "Degradar" (degrade), "contaminar" (contaminate), and "dañar" (damage) are actions that harm the environment, so they don't fit.

Answer:

A. conservar
