English Grammar — Spot the error (choose the incorrect part; select 'No error' if the sentence is correct). Sentence parts: A) Twenty-five kilometres B) from Bhubaneswar to Cuttack C) are D) a long distance. E) No error

Introduction / Context:
This question checks subject–verb agreement for distances, sums, and periods of time. In English, a distance expressed as a single measure typically takes a singular verb when viewed as a unit.

Given Data / Assumptions:

• Subject phrase: “Twenty-five kilometres from Bhubaneswar to Cuttack.”
• Predicate verb: “are.”
• Predicate complement: “a long distance.”

Concept / Approach:
Amounts taken as a unit (time, money, distance) generally agree with a singular verb: “Twenty-five kilometres is …,” “Ten years is …,” “Five hundred rupees is …” when treated as a single measure.

Step-by-Step Solution:

Verification / Alternative check:
Replace with singular noun “distance”: “This distance is long.” The predicate remains singular, confirming “is.”

Why Other Options Are Wrong:

• A: Correct numeral-noun phrase for distance.
• B: Locative prepositional phrase adds information, not agreement.
• D: Noun phrase complement is appropriate.
• E: Not applicable because C is erroneous.

Common Pitfalls:
Learners are distracted by the plural-looking “kilometres.” Treat the measure as a unit; use a singular verb in formal English when emphasizing the total amount as one entity.

Final Answer:
C) are
