In each of the questions, a sentence has been divided into four parts, one of which may contain an error. Identify that fragment and mark it as your answer. Mark (E) if the sentence contains no error.

"If you had (A)/ listened to the instructions (B)/ carefully, you won't (C)/ have made such mistakes." (D)

Solution

Conditional Structure: The sentence employs a third conditional structure, which expresses a hypothetical situation in the past that didn't happen and its imagined consequence. Past Tense in the Consequence: In third conditionals, the consequence clause (the part after the comma) requires the past perfect tense to convey that the hypothetical outcome didn't materialize. Therefore, "won't" needs to be corrected to "wouldn't" to maintain the correct tense structure within the conditional sentence.
