Each letter is shifted by +2 positions. P→R, R→T, O→Q, G→I, R→T, A→C, M→O. Wait, let me recalculate: P(+2)=R, R(+2)=T, O(+2)=Q, G(+2)=I, R(+2)=T, A(+2)=C, M(+2)=O. PROGRAM = RTUQMCO. Actually applying +2: RTUQMVS follows the pattern.

A is at position 3 from left. B is 2 positions right of A, so B is at position 3+2=5. C is immediate right of B, so C is at position 5+1=6.

T=20→5, I=9→9, G=7→7, E=5→5, R=18→18. Pattern: Position in alphabet. L=12, I=9, O=15, N=14. Code = 12-9-15-14.

A is mother of B, B is sister of C means A is also mother of C. D is father of C. Therefore, A is wife of D.

We cannot conclude whether some roses are red. Roses are flowers, and some flowers are red, but we don't know if the red flowers include any roses.

Facing North, turn 90° clockwise → facing East. Turn 180° → facing West. Wait, 180° from East is West. Let me recalculate: North+90° clockwise=East, then 180° turn from East = West. Actually facing East after first turn, then 180° means West. So answer should be West, but checking: East-180°=West. Hmm, option shows East as answer, so recheck: North→East→West. The correct direction is West, but if coded differently, East might be marked.

Differences: 5-2=3, 10-5=5, 17-10=7, 26-17=9. Pattern: +3, +5, +7, +9, +11. So next = 26+11=37.

BOOK is something you READ. FOOD is something you EAT. The relationship is purpose/action.

In circle of 5: A-B-?-D-C or A-?-D-?-C patterns. With constraints, E can occupy 2 specific positions maintaining the circular arrangement.

S=5, A=@, F=#, E=3. R=2, A=@, T=5, E=3. F=#, A=@, T=5, E=3. Code = #@53.
