English grammar error-spotting (reported meaning and voice): Read the sentence split into four labeled parts (A–D) and identify the part that contains a grammatical or idiomatic error; if there is no error, select ‘‘No error.’’ Focus on logical voice and meaning: ‘‘Arun's parents died when he was young and / he looked after his aunt / who had no children. / No error.’’

Given data

• A: ‘‘Arun's parents died when he was young and’’
• B: ‘‘he looked after his aunt’’
• C: ‘‘who had no children.’’
• D: ‘‘No error.’’

Concept / Approach
When a coordinating clause follows ‘‘… parents died when he was young’’, natural logic requires that the young child should be looked after by an elder/guardian, not that the child looked after the elder. The error is of voice and sense, which is tested under idiomatic/grammatical usage in error-spotting.

Step-by-Step evaluation
Step 1 (Part A): Grammatically fine. It sets up the background situation.Step 2 (Part B): ‘‘he looked after his aunt’’ conflicts with logic; the intended meaning clearly is the reverse.Step 3 (Part C): A non-restrictive/continuative clause—grammatically fine.

Correction
Suggested fix: ‘‘… and he was looked after by his aunt …’’ or more concise, ‘‘… and his aunt looked after him …’’

Common pitfalls

• Treating this as a purely grammatical tense error and missing the voice/meaning mismatch.

Final Answer
he looked after his aunt
