Introduction / Context:
This question checks idiomatic usage of “too … to” with an infinitive and the correctness of prepositional phrases describing duration. You must locate an error segment or confirm that no error exists.
Given Data / Assumptions:
- The structure “too + adjective + to + verb” expresses an excess preventing the action.
- “Concentrate on” is the standard preposition collocation.
- “For a long time” is a standard duration phrase.
Concept / Approach:
Evaluate each chunk independently: subject–verb agreement, infinitival complement, verb–preposition collocation, and duration phrase. Ensure the meaning is coherent: being too irritated prevents long concentration.
Step-by-Step Solution:
Part A: “He was too” — correct as the opening of the “too … to” construction.Part B: “irritated to” — correctly provides the adjective followed by the infinitive marker “to.”Part C: “concentrate on his work” — correct verb and collocation (“concentrate on”).Part D: “for a long time.” — standard duration phrase; punctuation acceptable.
Verification / Alternative check:
Full sentence reads naturally: “He was too irritated to concentrate on his work for a long time.” Synonymous rewrites preserve meaning, confirming correctness.
Why Other Options Are Wrong:
No segment exhibits a grammatical or idiomatic error; therefore “No error” is the best choice.
Common Pitfalls:
Misplacing the duration phrase (“for long time” without the article) or changing the collocation to “concentrate at” or “concentrate in,” which would be incorrect.
Final Answer:
No error.
