Digital PSAT Reading and Writing Practice Question 239: Answer and Explanation

Question: 239

Although some invasive species do cause tremendous and irreparable damage to their ecosystems, environments are not static; they change, develop, and adapt to transitions, whether these be natural or man-made. We must learn to be more discriminating in our eradication of invasive plants from those areas where they have become an integral part of the greater ecosystem.

As used in the text, what does the word "discriminating" most nearly mean?

  • A. Biased
  • B. Intolerant
  • C. Tasteful
  • D. Selective

Correct Answer: D

Explanation:

D. Although “discriminating” typically has a negative connotation that people associate with prejudice, in this context, the author is asserting that we need to be more careful and “selective” in deciding which invasive plants we keep and which ones we exterminate. Choices A and B can apply to discriminating in other contexts, and Choice C would only apply to being “discriminating” when it comes to the quality of art, food, music, etc.
