Select the grammatically correct sentence.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. The teacher from the South explained the theory in a detailed manner.
Error Concept: Article usage and noun modifiers.
What is wrong:
Option A uses incorrect articles ('a South' is wrong; it should be 'the South') and an incorrect expression ('in the detailed manner' is awkward).
Option B uses “detailed manners” which is incorrect, as “manner” in this context is uncountable and should remain singular.
Option D uses “an South,” which is incorrect because “South” begins with a consonant sound, so “the” should be used.
Grammar Concept:
-
Use “the” before regions like “the South.”
-
Use “a detailed manner” — correct article and collocation.
-
Avoid pluralizing abstract nouns unnecessarily — “manner” in this context should remain singular.
Incorrectness of the concept in context: The other options either use incorrect articles, improper plural forms, or violate idiomatic usage.
Correction: The sentence must use “the South” for the proper noun region, and “a detailed manner” to maintain correct idiomatic structure.
Corrected phrase: The teacher from the South explained the theory in a detailed manner.
Final sentence: The teacher from the South explained the theory in a detailed manner.
Hence, the chosen option is correct.
