Introduction / Context:
This “spot the error” question checks whether you can identify the correct verb–preposition collocation and avoid needless repetition. Natural English uses set phrases like “look after someone” to mean “take care of,” whereas “look at” merely means “see/observe.”
Given Data / Assumptions:
- The sentence says both brothers care for their parents.
- Segment C uses “look at,” which signals visual attention, not care.
- Segment D contains a stylistic redundancy “old and aged,” but redundancy is not always treated as the test error unless ungrammatical.
Concept / Approach:
Choose the option that contains a clear grammatical or lexical error affecting meaning. The idiomatic phrasal verb for caring is “look after.” Thus, “they look at their … parents very well” is wrong because it contradicts the intended sense of caregiving.
Step-by-Step Solution:
Spot the intended meaning: caring for parents.Check collocation: “look at” ≠ “take care of.”Replace with: “look after their parents very well.”Optional style fix: you may drop either “old” or “aged,” but this is stylistic, not the core error tested.
Verification / Alternative check:
Rewritten: “Both the brothers are so good-natured that they look after their aged parents very well.” The meaning now aligns with the context.
Why Other Options Are Wrong:
A: Acceptable Indian English for emphasis (“Both the brothers …”).B: Correct intensifier clause “so … that …”.D: Redundant but not ungrammatical; exams typically target the collocation error instead.
Common Pitfalls:
Confusing “look at” (see) with “look after” (take care of); over-focusing on redundancy and missing the wrong collocation.
Final Answer:
they look at their
