Reena introduces a woman as the sister of her uncle's brother. How is that woman related to Reena?

Appeared in: UP NHM CHO 7 Sept 2022(shift-1st)

Explanation

The core of the puzzle is to correctly identify the person described as 'her uncle's brother'.
In the most common and direct interpretation, an 'uncle's brother' is the subject's own father.
The sister of one's father is, by definition, their paternal aunt.
This relationship holds true even if the 'uncle's brother' refers to another uncle, as his sister would still be an aunt.

Option B: A cousin is the child of one's aunt or uncle, not the sibling of one's parent.
Option C: A sister shares the same parents. The woman in the question is from the previous generation (a sibling of Reena's father).
Option D: While the sister of a maternal uncle could be one's mother, the term 'aunt' is a more general and certain answer, as it also covers the paternal side. In reasoning puzzles, the most direct and unambiguous answer is preferred.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Blood Relations as background academic context rather than a clinical decision trigger.
While not a clinical question, logical reasoning is a critical skill for nurses for problem-solving and critical thinking in patient care scenarios.
Accurately understanding family relationships is crucial when taking a family medical history to identify genetic predispositions to diseases like diabetes, heart disease, or certain cancers.
What if the prompt was 'the only sister of her uncle's brother' and the uncle was maternal? In that specific case, the answer would be 'Mother', highlighting the need for precise language in clinical history taking.

How to Approach the Question

Identify the main subject of the sentence, which is Reena.
Break down the relationship described in reverse order: start with 'uncle's brother' and then find the 'sister' of that person.
Draw a simple family tree or diagram to visualize the connections. This helps avoid confusion.
Consider the most direct and common interpretation first (e.g., 'uncle's brother' = 'father').
Evaluate each option against your derived relationship to find the correct match.
