Directions: Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option ‘No error’ as the answer response. (Ignore errors of punctuation, if any).

Some researchers do not favor hasty conducted experiments (A) / because they do not (B) / like to rely on findings that (C) / have not been thoroughly verified (D).

The correct answer is Option A.

Explanation:
In part (A) of the sentence, the word "hasty" is used incorrectly. Here, "hasty" is an adjective trying to modify the past participle "conducted" (which acts as an adjective describing the noun "experiments").

To modify an adjective or a participle, we must use an adverb rather than an adjective. Therefore, the adjective "hasty" should be replaced by the adverb "hastily".

Corrected Sentence:
"Some researchers do not favor hastily conducted experiments because they do not like to rely on findings that have not been thoroughly verified."
