Snape's Logic Puzzle

Answer: VIEW

“It is a straightforward logic puzzle with no nasty tricks.”

Snape, being Snape, is lying. If one attempts to solve this logic puzzle as-is, one reaches a contradiction. Instead, one must treat the sentences that Snape says before and after the 29 statements as more statements, each of which has a truth value. After doing that, the logic puzzle is solvable, and one learns that

• The answer has 4 letters.
• The Scrabble value of the answer is 10.
• The second and third letters of the answer are both vowels.
• The first and last letters of the answer are alphabetically consecutive

The only word satisfying these constraints is VIEW, which is the answer.
