Question 1 / 2

1
Locate the grammatical error in the sentence: "Sixty miles are a good distance."
0:00
Solution: Step 1: Identify the subject: "Sixty miles". Although 'miles' is plural, when a plural noun phrase refers to a single quantity, amount, or unit considered as one entity (like a single distance, a period of time, or a sum of money), it functions as a singular subject. Step 2: Identify the verb: "are". This is a plural verb. Step 3: There is a subject-verb agreement error. Since 'Sixty miles' is treated as a singular concept (a single 'good distance'), it requires a singular verb. Step 4: Therefore, the segment "are" is incorrect. The correct verb should be "is". The correct sentence is "Sixty miles is a good distance.".

Locate the grammatical error in the sentence: "Block of Residential flats are coming up near our house."
0:00
Solution: Step 1: Identify the subject of the sentence: 'Block of Residential flats'. The head noun, which determines the verb's number, is 'Block', which is singular. Step 2: Identify the verb: 'are coming up'. This is a plural verb. Step 3: There is a subject-verb agreement error. A singular subject requires a singular verb. Step 4: Given that 'flats' (plural) are 'coming up', it is implied that there is more than one block. To match the plural verb 'are', the subject 'Block' should also be plural. Step 5: Therefore, the segment "Block of Residential flats" is incorrect. The correct phrase should be "Blocks of Residential flats".
