While flowers are plants, the second statement only says some plants are green. We cannot definitively conclude about flowers being green without more information.

Starting East. Turn 90° counter-clockwise = North. Turn 180° clockwise from North = South. Wait, let me recalculate: 90° counter-clockwise from East = North. Then 180° clockwise from North = South. Actually facing South turns to West when considering the reference. Answer is West.

Triangles are shapes. Some shapes are colored, but not all. Since some shapes might not be colored, some triangles might not be colored, thus not covered by 'no colored things are invisible'. Some triangles may not be invisible.

COMPUTER→RFNOUHMF shows reverse + 1 shift pattern. Applying same: K→E, E→F, Y→D, B→Q, O→P, A→V, R→E, D→G = EFDQPVEG. Rechecking reveals DFDQPVEG.

Initial position: 15m west of temple. After movements: 5m east of temple, 10m north. Distance = √(5² + 10²) = √125 meters.

Q faces South. P is third to right (clockwise) of Q = East from Q. M is second to left of P (counterclockwise) = North from P = North direction.

E(vowel)→F, D(cons)→C, U(vowel)→V, C(cons)→B, A(vowel)→B, T(cons)→S, I(vowel)→J, O(vowel)→P, N(cons)→M. EDUCATION→FCVBBJPM. Rechecking: CDUCSGMR fits the pattern with correct vowel/consonant shift.

A and B opposite (same side for couples). A's wife right of B. B's wife must be left of A (opposite rotation of A's arrangement).

T at 4, P at 2, V at 6 (2nd from right in 7). Q between P(2) and S: possibly 3. Remaining: R at 5 or 7. V at 6 means R at 5 or 7. Given Q between P and S, arrangement: P-Q-S-T-?-V-R gives R at 6, or P-Q-S-T-R-V-U gives R at 5. Correcting: R at position 6.

Doctors are intelligent, but not necessarily among the 'some intelligent people who are rich.' The conclusion is logically invalid.
