Find the part of the sentence that contains an error: The company needs a detailed feedback (1)/ from all departments (2)/ before finalising its restructuring plan (3)/ for the upcoming fiscal year. (4)/
- (a)(1)
- (b)(2)
- (c)(3)
- (d)(4)
Answer
Why
Correct — A. The error is in part (1): a detailed feedback.
Feedback is an uncountable noun, like advice and information. It takes no a/an and no plural -s.
Repair: "The company needs detailed feedback from all departments" → option (a).
Why the others are wrong
- (b)(2) — from all departments is sound: all takes the plural departments, and from names where the feedback comes from. Nothing here needs repair.
- (c)(3) — before finalising puts the -ing form after the preposition before, and its agrees with the singular company. Finalising is the British spelling, not an error.
- (d)(4) — for the upcoming fiscal year is a correct time phrase: for marks the period the plan covers. The part is sound.
Concept
Uncountable nouns name a mass or an abstract idea rather than separate items. They take a singular verb, no a/an and no plural -s.
Nouns that behave this way include feedback, advice, information, luggage, furniture, equipment and evidence.
To count them, add a unit noun — a piece of advice, an item of luggage — or use some: some feedback.
The adjective is the disguise. Detailed describes the feedback but does not turn it into a countable noun, so the article still has to go.
Key facts
- Feedback is uncountable: detailed feedback or some feedback, not a feedback or feedbacks.
- Advice, information, luggage, furniture, equipment and evidence are uncountable in the same way.
- A verb placed straight after the preposition before takes the -ing form: before finalising.

Common traps
- Letting the adjective hide the article: a detailed feedback reads smoothly, but feedback is still uncountable
- Scanning the later parts for a preposition or tense slip and passing over the article in part (1)
Here the uncountable noun is given an article: a detailed feedback.
The plural form of the same slip is keyed at 26 Sep 2025, 12:30, English Q.16 (Several of the evidences), 9 Sep 2024, 09:00, English Q.4 (no informations) and 23 Sep 2024, 16:00, English Q.15 (my luggages).
