Q is the brother of R. P is the sister of Q. T is the brother of S. S is the daughter of R. Based on this information, who are the children of R?

Introduction / Context:
Although the original wording was confusing, this repaired version of the question focuses on a simple task: identifying which people are the children of a given person R, based on a short set of family relations. This is a basic exercise in reading relational statements carefully and grouping people by generation.

Given Data / Assumptions:

• Q is the brother of R, so Q and R are siblings and both are in the same generation.
• P is the sister of Q, so P is also a sibling in that same generation.
• T is the brother of S, so T and S are siblings and younger than their parent.
• S is the daughter of R, so S is a child of R.
• We assume T and S share both parents, so they are both children of R, unless stated otherwise.

Concept / Approach:
The strategy is to divide all the given people into two levels. The first level includes the siblings Q, R and P. The second level includes the children of R, who are S and T. Then, from the list of options, we select the pair that matches the children of R.

Step-by-Step Solution:
Step 1: From "Q is the brother of R", both Q and R are in the same generation and Q is male.Step 2: "P is the sister of Q" places P in the same generation as Q and R and shows that P is female.Step 3: "S is the daughter of R" places S one generation below R and shows that S is a female child of R.Step 4: "T is the brother of S" makes T a male sibling of S. Since S is a daughter of R, it is natural in such questions to treat T as another child of R.Step 5: Thus, S and T together form the set of children of R mentioned in the problem.Step 6: Looking at the answer choices, the pair that lists S and T together is option d.

Verification / Alternative check:
You can sketch the family quickly. Place Q, R and P side by side at the parent generation. From R, draw two downward lines to S and T. Mark S as daughter and T as son. Now it is visually obvious that S and T are in the child generation under R, whereas Q and P are siblings of R, not children. This drawing confirms that S and T are the required answer.

Why Other Options Are Wrong:
Options a and e mention R, but R is in the parent generation, not the child generation, so R cannot be his own child. Option b lists P and T, but P is clearly a sibling in the older generation, not a child of R. Option c lists Q and T; again Q is shown as the brother of R, not a child of R.

Common Pitfalls:
Candidates sometimes rush and misread the lines, treating all four letters P, Q, R and S as siblings or all as children. Carefully noting words like brother, sister, daughter and placing everyone into the correct generation helps avoid these errors. If you are ever unsure, a quick tree diagram usually makes the relationships much clearer.

Final Answer:
The children of R in this family are S and T.
