In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select “No Error”. These five sisters (1) / care for one other (2) / like mothers. (3) / No Error (4).

Introduction / Context:
This error-spotting question focuses on the correct use of reciprocal pronouns in English. When talking about two or more people who act towards each other, we typically use “each other” or “one another”, not “one other”. The sentence describes five sisters and how they care for each other, so we must choose the right reciprocal expression.

Given Data / Assumptions:

• Part (1): “These five sisters”.
• Part (2): “care for one other”.
• Part (3): “like mothers.”
• Part (4): “No Error”.
• The intended meaning is that the sisters care for each other in a very loving way, like mothers.

Concept / Approach:
English uses “each other” and “one another” as reciprocal pronouns. “Each other” is typically used for two people, and “one another” is often used for more than two, although in modern usage the distinction is not always strict. The form “one other” without “an” does not function as a correct reciprocal pronoun; it simply means “a different one” in other contexts. Here, because the subject is “five sisters”, the correct phrase should be “care for one another” or “care for each other”.

Step-by-Step Solution:
Read Part (1): “These five sisters” – correct subject and clear that more than two people are involved.Read Part (2): “care for one other” – this sounds wrong; we expect “each other” or “one another”.Read Part (3): “like mothers.” – correct simile; suggests they care very deeply.The error is the phrase “one other” in Part (2); the correct reciprocal pronoun is “one another”.A correct version: “These five sisters care for one another like mothers.”

Verification / Alternative check:
Replace “one other” with “one another”: “These five sisters care for one another like mothers.” This now sounds natural and grammatically correct in English. We could also say “care for each other like mothers”, which is also acceptable. However, “care for one other” is never used as a reciprocal pronoun structure in standard English.

Why Other Options Are Wrong:
Part (1) simply introduces the subject correctly. Part (3) “like mothers” is fine because it compares the intensity of care to that of mothers. Since the only clear error is in Part (2), Option “2” is the right answer. “No Error (4)” cannot be chosen because the phrase “one other” is grammatically incorrect in this context.

Common Pitfalls:
Students often get confused between “one another” and “one other” due to speed-reading. Remember that “one another” and “each other” are established reciprocal pronouns expressing mutual actions among people, whereas “one other” is not used for this purpose. Whenever you see a group like “five sisters”, quickly check if the reciprocal pronoun after it has the necessary “an” in “another”.

Final Answer:
The error is in part 2; it should be “care for one another”.
