English Grammar — Spot the error (choose the incorrect part; select 'No error' if the sentence is correct). Sentence parts: A) He was very disappointed B) when he found C) that someone else D) had secured higher marks. E) No error

Introduction / Context:This question checks tense sequencing in reported content and idiomatic use of “disappointed.” The sentence narrates a past event with a prior action embedded via past perfect.

Given Data / Assumptions:

• Main clause: “He was very disappointed.”
• Time of realization: “when he found …”
• Earlier action: “someone else had secured higher marks.”

Concept / Approach:Past perfect (“had secured”) is used for an action completed before another past moment (“found”). The pattern “was disappointed when he found that …” is idiomatic and standard.

Step-by-Step Solution:

Verification / Alternative check:Change the embedded verb to simple past: “someone else secured higher marks.” The meaning remains, but past perfect neatly shows prior completion; both can be acceptable, so the given is certainly not erroneous.

Why Other Options Are Wrong:

• A–D: Each part is grammatical and idiomatic.
• E: Correct because the sentence contains no error.

Common Pitfalls:Over-correcting to remove past perfect even when it clarifies sequence. Keep it when you want to foreground an action preceding another past point.

Final Answer:E) No error
