The Hypotheses
The first hypothesis: the second hypothesis is false, whereas the third one is true.
The second hypothesis: the fourth hypothesis is true, whereas the sixth is false.
The third hypothesis: the fourth hypothesis is false, whereas the fifth is true.
The fourth hypothesis: hypotheses no. two and six are both true.
The fifth hypothesis: the first hypothesis is true, whereas the second is false.
The sixth hypothesis: the fourth hypothesis is false, whereas the fifth is true.
At least one of these hypotheses is true.
So there is a question: Which are false?
