You meet an alien, who you learn is thinking of a positive integer n. They ask the following three questions.
“Am I the kind who could ask whether n is divisible by no primes other than 2 or 3?"
“Am I the kind who could ask whether the sum of the divisors of n (including 1 and n themselves) is at least twice n?"
“Is n divisible by 3?"
Is this alien a Crick or a Goop?
