If {h} denote the remainder when 3h is divided by 2 then which of the following is equal to 1 for all positive integers h?
I. {2h+1}
II. {2h}+1
III. 2{h+1}
Choices.
A) I only	B) II only	C) I and II	D) III only	E) II and III
I and II - I and II   3h/2 = 0 or 1   I just substituted 1 in the equations and solved.
