The following sentence has been split into four segments. Identify the segment that contains an error.
The newspaper reported / that it was a mystery / how the thieves enter / into the house.

Correct option is B

Option (b) contains an error.
Explanation of error:
The verb “enter” is in present tense, but the sentence is in the past tense. The clause “how the thieves enter” should also be in the past tense to maintain tense consistency.
Correct Sentence:
The newspaper reported that it was a mystery how the thieves entered into the house.
Grammatical rule used:
When the reporting verb (e.g., reported) is in the past tense, the verb in the subordinate clause should also be in the past tense (unless it's a universal truth).
Example:
Incorrect: He said that he is hungry.
Correct: He said that he was hungry.
�� Information booster:
In reported speech and indirect narration, we must backshift the tense when the reporting verb is in the past.
