Study the given information carefully and answer the questions given below.

Seven students—A, B, C, D, E, F, and G—give presentations on seven different subjects: History, Math, Science, Art, Music, Geography, and Civics, from Monday to Sunday. A presents History on Monday. Three presentations are scheduled between A and E, who presents Music. The number of students presenting before B is the same as the number of students presenting after F, who presents Geography on Saturday. Four students present between B and the one who presents Civics. C presents immediately after the one who presents Math, and immediately before D, who presents Art.

On which day is the Math presentation scheduled?

The correct option is Tuesday.

Let's deduce the presentation schedule step-by-step from Monday to Sunday using the given information:

1. Day and Initial Assignments:
- The days are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.
- A presents History on Monday.
- F presents Geography on Saturday.

2. Position of E:
- Three presentations are scheduled between A and E.
- Since A is on Monday (Day 1), placing 3 days between them (Tuesday, Wednesday, Thursday) puts E on Friday (Day 5).
- E presents Music on Friday.

3. Position of B:
- The number of students presenting before B is equal to the number of students presenting after F.
- F is on Saturday (Day 6), so exactly 1 student presents after F (on Sunday).
- Therefore, exactly 1 student must present before B, which means B presents on Tuesday.

4. Position of Civics:
- Four students present between B (Tuesday, Day 2) and the one who presents Civics.
- Counting four days after Tuesday (Wednesday, Thursday, Friday, Saturday), the student on Sunday (Day 7) presents Civics.

5. Positions of C, D, and Math:
- C presents immediately after the one who presents Math, and immediately before D, who presents Art.
- This forms a continuous sequence: [Math] → [C] → [D (Art)].
- Looking at the available days: Monday (A-History), Tuesday (B-?), Wednesday (Free), Thursday (Free), Friday (E-Music), Saturday (F-Geography), Sunday (?-Civics).
- The only consecutive sequence of days available for Math, C, and D is Tuesday, Wednesday, and Thursday:
  • Tuesday: B presents Math.
  • Wednesday: C presents Science (the remaining subject).
  • Thursday: D presents Art.
  • Sunday: G presents Civics (G is the remaining student).

Final Schedule Summary:
• Monday: A - History
• Tuesday: B - Math
• Wednesday: C - Science
• Thursday: D - Art
• Friday: E - Music
• Saturday: F - Geography
• Sunday: G - Civics

Thus, the Math presentation is scheduled on Tuesday.
