The correct answer is an explanation of the word’s meaning.
Reasoning: In the sentence, the phrase "to eradicate invasive wildlife involves first identifying the harmful species and then making the habitat less hospitable to them" provides context that explains the process of making it difficult for the harmful species to thrive. This suggests that "eradicate" means to eliminate or get rid of something. The action described—making the habitat less hospitable—clarifies what is meant by "eradicate."
