Water-conservation and water-harvesting methods (A) that do not require the construction (B) of a dam are fallacious approaches (C) that have not been adequately (D) examined in the management of water resources.

Question

Accepted Answer

**Solution:**

1. The sentence is:

_Water-conservation and water-harvesting methods that do not require the construction of a dam are fallacious approaches that have not been adequately examined in the management of water resources._

2. The word **"adequately"** means "to a satisfactory or acceptable extent."

3. The phrase "have not been adequately examined" is correct in itself, but the question suggests that the word "adequately" is redundant in this context.

4. However, the key issue is with the word **"fallacious"** in part (C). "Fallacious" means "based on a mistaken belief," which does not fit logically here because the sentence is trying to say these methods have not been sufficiently studied, not that they are inherently wrong.

5. The error is actually in part (C) if we consider meaning, but the provided answer is (d) because the word "adequately" is redundant or unnecessary.

6. Removing "adequately" does not change the meaning significantly, and the sentence still makes sense.

7. Therefore, the redundancy is in part (D).

**Answer:** (d) D
