DFriday

Answer:

D. Friday

Read Explanation:

T goes to swim on Friday.

  1. P and U: P swims on Saturday (Day 6). Since exactly three people swim between P and U, U must swim on Tuesday (Day 2).

  2. U and T: Exactly two people swim between U and T. Counting forward from Tuesday, T must swim on Friday (Day 5).

  3. S and V: Exactly three people swim between S and V. The only remaining slots that are 4 days apart are Wednesday (Day 3) and Sunday (Day 7).

  4. S, R, and Q:

    • Exactly two people swim between S and R. If S were on Wednesday, R would have to be on Saturday (already taken by P) or before Monday (impossible). Therefore, S is on Sunday and V is on Wednesday.

    • Counting back two people from Sunday (S) places R on Thursday.

    • Exactly two people swim between Q and R, which places Q on Monday.
