English Grammar – Spot the error (choose the erroneous segment or ‘‘No error’’). Sentence: I asked him whom he thought would be able to get the first prize.

Introduction / Context:
The item tests case in indirect questions. In “wh-” clauses, choose “who” or “whom” based on the pronoun’s function within the embedded clause, not by what precedes the clause.

Given Data / Assumptions:

• Main reporting verb: “asked”.
• Embedded clause: “(who/whom) he thought would be able to get …”.
• Within the embedded clause, the pronoun is the subject of “would be able”.

Concept / Approach:
Rule: Use “who” for subjects, “whom” for objects. Here the structure is “he thought [who would be able …]”. The pronoun is subject of “would be able,” so it must be “who,” not “whom”.

Step-by-Step Solution:

Verification / Alternative check:
Paraphrase: “Who would be able …, he thought.” Clearly, “who” is the subject. “Whom” would only be correct if it were the object, e.g., “whom he thought I should select.”

Why Other Options Are Wrong/Acceptable:

• A, C, and D are fine.
• E cannot be right since B contains a case error.

Common Pitfalls:
Overusing “whom” after verbs like “ask” because it feels formal; forgetting to analyze the embedded clause independently.

Final Answer:
whom he thought
