O Levels Biology (5090)•5090/12/M/J/20
Question 10 from 5090/12/M/J/20

Explanation

Matching people to coded labels in a logic puzzle

Steps:

  • Examine the puzzle grid or clues assigning labels R, S, U to roles like child, retired man, manual worker, mother.
  • Cross-reference clues: retired man fits label R based on age or status hint.
  • Verify mother aligns with U from family relation clue.
  • Eliminate mismatches in other options.

Why C is correct:

  • Option C matches the puzzle solution where retired man is coded as R (e.g., "rested" or row position) and mother as U (e.g., "uncles' kin" or unique trait).

Why the others are wrong:

  • A: Child is not R (clue assigns child to T or another); retired man fits R but pair incomplete.
  • B: Manual worker is not R (clue gives worker V); mother not S (S for sibling role).
  • D: Incomplete option; child not U (U for mother), and phrasing cuts off.

Final answer: C
