Out of the options given below, choose the sentence which is grammatically incorrect:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → The price of tomatoes have gone up again this week.
Subject-verb agreement when a phrase comes between the subject and the verb:
- The given sentence says “The price of tomatoes have gone up”.
- The subject is “the price”, not “tomatoes”. “Of tomatoes” only tells us which price.
- “Price” is singular, so the verb must be singular: “has gone up”.
- Corrected: The price of tomatoes has gone up again this week.
Why the Other Options are Incorrect?
Option 1: Bread and butter is my little brother’s usual breakfast before school. This sentence is correct. “Bread and butter” is one dish, so it takes the singular verb “is”.
Option 3: The elderly in our colony walk in the park every morning. This sentence is correct. “The elderly” means elderly people, so it is plural and takes “walk”.
Option 4: Swimming in the canal is not allowed during the monsoon. This sentence is correct. “Swimming in the canal” is one activity, so it takes the singular verb “is”.
