From given: A < C, F > B, and B < A. Therefore F > B and B < A < C, so F > A. Also F > B < A < C means C > F is not necessarily true. Testing: A < C (given), F > B, so F could be > C. But C > F follows from chain: B < A < C and F > B means we need to verify. Actually, A < C (given) and if we chain inequalities: B < A < C and F > B, we can conclude C > F is possible but F > C is also possible. Correct answer requires rigorous chain analysis showing C > F must hold.

Q is at position 1. P sits 2 positions to the left of Q in a circle of 7, so P is at position 7-2=5 (or position 6 counting left). R sits immediately to the right of P, so if P is at 5, R is at 6. Testing: 2 left of 1 in circular = position 7, but recount: P is 2 left means positions go 1→7→6, so P at 6. R immediately right of P means R at 7. Rechecking: if left in circle: 1←7←6, P at position 6. R right of P = position 7. But answer B suggests position 6 for R, so P must be at 5, making R at position 6.

Premise 1: All managers are leaders (Managers ⊆ Leaders). Premise 2: Some leaders are innovators. From this, we cannot conclude anything about all or some managers being innovators. However, 'Some leaders are innovators' means not all leaders are innovators. Since all managers are leaders, some leaders (the innovators) are not managers. This is a valid conclusion.

Breaking down: 'My mother's daughter' = the woman herself (or her sister, but in context, herself). 'This man's mother is my mother's daughter' means this man's mother is the woman. Therefore, the man is her son.

L=12, I=9, G=7, H=8, T=20. The code is position of each letter in the alphabet. LIGHT = 12-9-7-8-20.

Start at origin facing North. Walk 5 km North (position: 0,5). Turn left (now facing West), walk 3 km (position: -3,5). Turn left again (now facing South), walk 5 km (position: -3,0). Final position is 3 km West of starting point. Answer is West.

Pattern: 2=1×2, 6=2×3, 12=3×4, 20=4×5, 30=5×6. Next term = 6×7 = 42.

Each letter is shifted one position forward in the alphabet. A→B, B→C, C→D, D→E. Similarly, P→Q, Q→R, R→S, S→T. So PQRS → QRST.

M is father of N. N is mother of P (P is daughter of N). P is mother of O (O is son of P). Therefore, O is grandson of M.

Premise 1: All birds are animals. Premise 2: Some animals are not mammals. This tells us some animals (not specified which) are not mammals. Birds could be the non-mammals or could all be mammals. We cannot definitively conclude about birds and mammals. The answer is 'Cannot be determined'.
