Choose the part of the following sentence that contains an error:
The most important feature of our products are that they are all created by hand.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → of our products are that
The verb agrees with the head noun of the subject, not with a noun inside a phrase that follows it. Here the subject is "The most important feature" (singular); "of our products" only describes it.
Option 1: The most important feature — No error. The superlative "the most important" is correctly formed.
Option 2: of our products are that — Error. The verb must agree with "feature", so "are" should be "is".
Corrected: of our products is that
Option 3: they are all — No error. "They" refers to the products (plural), so "are" is right here.
Option 4: created by hand — No error.
Correct sentence: The most important feature of our products is that they are all created by hand.
Example: The quality of these mangoes is excellent.
