Each letter is shifted 2 positions forward in the alphabet. E→G, X→Z, A→C, M→O, I→K, N→P, A→C, T→V, I→K, O→Q, N→P.

The conclusion doesn't necessarily follow. 'Some intelligent' doesn't confirm 'some scholars' are ambitious, as the overlap between scholars and ambitious people is not established.

All are perfect squares of consecutive numbers (12², 13², 14², 15², ?, 18²). 289 = 17² breaks the pattern slightly, but actually all fit. Review: 324 = 18², so sequence has gaps. 289 = 17² is the odd one as it breaks the consecutive pattern.

First letter decreases (Z→Y→X→W→V), middle number increases (1→2→3→4→5), last letter increases (A→B→C→D→E).

Insufficient information provided about positions of all people relative to given constraints.

PLANT produces FLOWER. Similarly, TREE produces FRUIT as its characteristic output/product.

Each letter is converted to its position in the alphabet. M=13, I=9, N=14, D=4.

The given conditions don't establish a direct comparison between Container 2 and Container 5.

Woman's mother's only daughter = the woman herself. So the man's mother is the woman = the man is the woman's son.

C sits immediately to the right of A. Therefore, C sits between A and the next corner on the North side.
