All others are writing/reading materials or have written content. Sharpener is a tool for maintenance.

M at position 4, N at position 5. S at position 7 (2nd from right in 8-person row). Between positions 5 and 7 = 1 person. Recount: positions 5 to 7, people between = position 6 only = 1 person. Check: S at 7, between 5 and 7 = just 6, that's 1 person.

First statement guarantees all politicians are ambitious, but second statement only guarantees some ambitious are honest, not all. Statement A assumes all are honest - not necessarily true.

P is Q's son. Q is R's mother, so P is R's uncle. R is S's father, so P is S's uncle.

Differences: +1, +2, +3, +4, +5, +6. Next: 17+6=23

Elegant implies grace; brutal implies cruelty. Synonymous relationship.

In circular arrangement with 6 people: B opposite E means 3 seats apart. A right of B. C between D and F means F-C-D or D-C-F. Testing positions: B at 1, A at 2 (right), E at 4 (opposite). Remaining D,C,F for 3,5,6. If D at 3, C at 5, F at 6: C is left of D. If D at 6, C at 3, F at 5: F is left of D. Checking constraint 'C between D and F': F(6)-C(5)-D(3) works in circular. Left of D(3) is C(5).

From 'All writers are creative' and 'Some creative people are teachers', we cannot definitively conclude whether any teachers are writers. Teachers could be creative without being writers. The conclusion is uncertain.

Differences: 4, 6, 8, 10, 12, 14, 16. Pattern increases by 2 each time. 42 + 14 = 56. Next would be 56 + 16 = 72.

D=4, E=5, A=1, R=18 (position from end of alphabet: D=23→4, E=22→5, A=26→1, R=9→18). For CARE: C=3, A=1, R=18, E=5 = 3-1-18-5.
