When Alice entered the Forest of Forgetfulness, she forgot the day of
the week. She met the Lion and the Unicorn resting under a tree. The
Lion lies on Mondays, Tuesdays and Wednesdays and tells the truth
on the other days of the week. The Unicorn, on the other hand, lies
on Thursdays, Fridays, and Saturdays, but tells the truth on the other
days of the week. They made the following statements:
Lion: \Yesterday was one of my lying days."
Unicorn: \Yesterday was one of my lying days."
From these two statements, Alice was able to deduce the day of the
week. What day was it? Choose the correct choice from the following answers.
A) Monday	B) Wednesday	C) Thursday	D) Friday	E) Sunday
If the Lion is telling the truth, the day of the week must be Thursday. If he   is lying, then the day of the week must be Monday. So the day of the week must be   either Thursday or Monday. If the Unicorn is telling the truth, the day of the week must   be Sunday. If he is lying, then the day of the week must be Thursday. The day of the   week cannot be Sunday (since we have already said that it must be Thursday or Monday).   Therefore, it must be Thursday   correct answer Thursday
