The following sentence has been split into four segments. Identify the segment that contains an error.
John is really / good in / playing / the piano.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 2 i.e. good in
Error Concept: Incorrect preposition usage after adjectives.
What is wrong: The phrase “good in” is incorrect in this context.
Grammar Concept: After the adjective “good”, we use the preposition “at” when we talk about someone's skill or ability in doing something.
Incorrectness of the concept in context: “Good in” is not used to talk about skills. The correct preposition to show someone’s ability in an activity is “at”.
Correction: “Good in” should be replaced with “good at”.
Corrected phrase: good at
Final sentence: John is really good at playing the piano.
Hence, the chosen option is correct.
