Answer 1

Answer:

Well, The first second and third circle represent Women, Liars and Men respectively. Now, because some, but not all, Men and Women are Liars, therefore only a part of the circles for Women and Men intersect with the Liars circle. Also, as no Men can be Women, therefore the two circles are disjoint.

Hope it helps!
