Directions (25-29): Study the information carefully and answer the questions given below.

Seven friends - P, Q, R, S, T, U, and V - went to attend a cooking class for a week from Monday to Sunday, not necessarily in the same order. Each person prepared a different number of dishes during these classes.

Q prepared the most dishes. The person who prepared the least dishes attended immediately after R. S prepared the 2ndmost dishes and attended on Sunday. T and the person who prepared the second-most dishes attended on consecutive days. Q prepared 5 dishes more than T who prepared 6 dishes more than P. P attended the classes immediately after the person who prepared 9 dishes. The person who prepared 10 dishes attended immediately before the person who prepared 8 dishes. Q attended on Wednesday, while V attended on Friday. There were 2 people between R and the person who prepared 6 dishes. Only One person prepared half number of dishes than the other one.

Who attended the cooking class on Thursday?

To find out who attended the cooking class on Thursday, we can systematically analyze the given clues step-by-step:

Step 1: Set up the weekly schedule
The days of the week are from Monday to Sunday. Let's fill in the definite positions first:
- "Q attended on Wednesday, while V attended on Friday."
- "S prepared the 2nd most dishes and attended on Sunday."
This gives us our initial schedule:

Monday: _
Tuesday: _
Wednesday: Q
Thursday: _
Friday: V
Saturday: _
Sunday: S (2nd most dishes)

Step 2: Determine T's attendance day
- "T and the person who prepared the second-most dishes attended on consecutive days."
Since Sunday (S) has the 2nd most dishes, T must attend on a day adjacent to Sunday. The only adjacent day available is Saturday. Therefore, T attended on Saturday.

Monday: _
Tuesday: _
Wednesday: Q (most dishes)
Thursday: _
Friday: V
Saturday: T
Sunday: S (2nd most dishes)

Step 3: Determine P's attendance day
- The remaining days for P, R, and U are Monday, Tuesday, and Thursday.
- "P attended the classes immediately after the person who prepared 9 dishes."
P cannot attend on Monday because there is no day before Monday in this weekly schedule. If P attended on Thursday, the person on Wednesday (Q) must have prepared 9 dishes. However, Q prepared the most dishes, and we know that Q prepared 5 dishes more than T, who prepared 6 dishes more than P. If Q prepared 9 dishes, then P would have prepared a negative number of dishes ($9-5-6=-2$), which is impossible.
Therefore, P must have attended on Tuesday. Consequently, the person who attended on Monday prepared 9 dishes.

Step 4: Determine R and U's positions
- The remaining slots for R and U are Monday and Thursday.
- "There were 2 people between R and the person who prepared 6 dishes."
Let's test both possibilities for R:
- If R attended on Thursday, the person who prepared 6 dishes must be either on Monday (which is impossible since Monday's person prepared 9 dishes) or on Sunday (S). But S prepared the 2nd most dishes, and since Q is the most, T prepared $x+6$ dishes, and P prepared the least dishes, S cannot be 6.
- Therefore, R must have attended on Monday. This means the person who attended on Thursday prepared 6 dishes.
- As a result, U must be the person who attended on Thursday.

Thus, U attended the cooking class on Thursday.
