The sentence is divided into four segments: (A), (B), (C), and (D). Identify the segment that contains a grammatical error. If the sentence is both grammatically and contextually correct, select “No error” as the correct answer.

The athlete had (A)/ broke the previous (B)/ championship record before (C)/ turning professional. (D)

Correct option is B

The correct answer is B

Explanation:
The error is in segment (B). The simple past tense verb form 'broke' has been wrongly combined with the past perfect auxiliary verb 'had'.

Grammatical Rule:
The past perfect tense construction always requires the past participle form (V3) of the main verb following the auxiliary verb 'had'. The forms of the verb are: Break (V1) - Broke (V2) - Broken (V3). Hence, 'broke' must be replaced with 'broken'.

Sentence Structure:
Subject + had + Past Participle (V_3) + Object$

Example:
• Incorrect: They had wrote the final script yesterday.
• Correct: They had written the final script yesterday.

Explanation of each part:

• Part A: 'The athlete had' forms the subject and the past perfect auxiliary element. It is grammatically correct.

• Part B: 'broke the previous' contains the error. The V2 form 'broke' must change into the V3 form 'broken'.

• Part C: 'championship record before' properly states the direct object along with the conjunction 'before'.

• Part D: 'turning professional.' correctly utilizes the gerund clause form after the preposition/conjunction 'before'.

Conclusion:
Changing 'broke' to 'broken' corrects the tense error in the sentence.

So the correct answer is (b)
