The correct answer is: B. has little value
The sentence is in the simple past tense, so the verb “to have” should also be in the simple past tense. The other options are either in the present tense or the past participle tense, which are both incorrect.
Here is a breakdown of each option:
- A. had belittled value is incorrect because the verb “to belittle” means to make something seem less important or valuable. In this sentence, the scientific method is not being made to seem less important, but rather is being said to have little value.
- B. has little value is correct because it is in the simple past tense and agrees with the subject of the sentence, “The scientific method.”
- C. have little value is incorrect because it is in the plural form, but the subject of the sentence is singular.
- D. No correction required is incorrect because the sentence is not grammatically correct.
