Question 1

A statement reads: 'All glurps are snarks. No snarks are bleebs.' Which must be true?

No glurps are bleebs

All glurps are snarks, and no snarks are bleebs, so by transitivity no glurps can be bleebs.

Question 2

A farmer has 17 sheep. All but 9 die. How many sheep are left?

Accepted Answer

9

Answer

'All but 9' means 9 survive, regardless of the total starting number.

Accepted Answer

32

Answer

4, 9, 16, 25, and 36 are all perfect squares; 32 is not (it's 2⁵).
