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.

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

M is uncle of N. N is sister of O, so M is also uncle of O. O is father of P, so P is nephew of O's uncle M.

Some politicians are honest, and all honest people are trustworthy, therefore some politicians must be trustworthy (through the chain).

North 10 km, then East 15 km brings net position 15 km East. Then South 10 km cancels the North movement. Final position: 15 km East of start.

D=4, R=18, E=5, A=1, M=13 (position in alphabet). S=19, L=12, E=5, E=5, P=16.

In circular arrangement: B-A-C order with A between B and C. D opposite B. E left of A means E-A-C arrangement. F must be opposite A.

From the given statements, we cannot conclude that some teachers are researchers as researchers may only come from non-teacher educators.
