Question
Directions: In each of the questions, a sentence has
been divided into four parts, one of which may contain an error. Identify that fragment and mark it as your answer. The words in bold are contextually and grammatically correct. Mark (E) if the sentence contains no error. The scientist's groundbreaking research, (A)/ marked by rigorous experimentation and innovative methodologies, (B)/ have revolutionized our understanding of (C)/ quantum mechanics and its intricate complexities. (D)/ No error (E)Solution
The subject "groundbreaking research" is singular, so the verb "have" should be corrected to "has" to maintain proper subject-verb agreement.
