Which of the following sentences has an error in subject-verb agreement?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Most of the milk in the fridge have turned sour because of the power cut.
Subject-verb agreement with “most of”:
- The given sentence says “Most of the milk ... have turned sour”.
- After “most of”, the verb agrees with the noun that follows it. Here that noun is “the milk”.
- “Milk” cannot be counted, so it takes a singular verb: “has turned”.
- Corrected: Most of the milk in the fridge has turned sour because of the power cut.
Why the Other Options are Incorrect?
Option 1: Both the kitchen and the dining hall were cleaned before the guests arrived. This sentence is correct. Two subjects joined by “both ... and” are plural, so “were” is right.
Option 2: The poor in our city depend on free rations from government shops. This sentence is correct. “The poor” means poor people, so it is plural and takes “depend”.
Option 3: One of my uncles runs a sweet shop in Kochi. This sentence is correct. The subject is “one”, not “uncles”. “One” is singular, so “runs” is right.
