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.

He agreed (A)/ to repair the broken handle (B)/ before the (C)/ guests was supposed to arrive. (D)

Correct option is D

Sentence given:
He agreed (A)/ to repair the broken handle (B)/ before the (C)/ guests was supposed to arrive. (D)
Step 1: Spot the error
Look at part (D): “guests was supposed to arrive.”
· Subject = “guests” (plural).
· Verb = “was” (singular).
· Rule: Subject and verb must agree in number (singular subject → singular verb; plural subject → plural verb).
· Correct form: “guests were supposed to arrive.”
So the error is in (D).
Step 2: Grammar rule
Subject-Verb Agreement Rule:
A verb must agree with its subject in number and person.
· Singular subject → singular verb (e.g., The boy was running).
· Plural subject → plural verb (e.g., The boys were running).
Step 3: Sentence structure
· Main clause: He agreed to repair the broken handle
· Subordinate time clause: before the guests were supposed to arrive.
Step 4: Corrected sentence
He agreed to repair the broken handle before the guests were supposed to arrive.
Step 5: Example for clarity
Incorrect: The teachers was preparing for the meeting.
Correct: The teachers were preparing for the meeting.
Correct Answer: (d) D
