Identify the part of the sentence that contains an error.
Fifty miles / are / a good distance.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → are
“Fifty miles” looks plural. But here it is one distance, taken as a single amount. An amount of distance, money or time taken as one whole takes a singular verb. So “are” should be “is”.
Option 1: Fifty miles — No error.
Option 2: are — Error. “are” should be “is”.
Option 3: a good distance — No error.
Corrected: Fifty miles is a good distance.
