The sentence is divided into four segments: (A), (B), (C), and (D). Identify the segment that contains a grammatical error. If the sentence is both grammatically and contextually correct, select “No error” as the correct answer.
A unpredicted surge in network traffic (A)/ has compelled the IT department to upgrade (B)/ server infrastructure as a precautionary (C)/ step to avoid system failure. (D)
Correct Answer :
A
Solution :
The correct answer is (A).
Explanation:
Segment (A) contains a grammatical error due to the incorrect use of the indefinite article "A".
The adjective "unpredicted" starts with a vowel sound, so it must be preceded by the article "An" instead of "A".
Corrected Sentence:
An unpredicted surge in network traffic has compelled the IT department to upgrade server infrastructure as a precautionary step to avoid system failure.
Therefore, the segment containing the error is (A).
