Hi, the following two math questions are from kaplan premiere program 2008 edition pg 288 practice questions. Please solve and explain why the answer is so… please…

Q2. *i cant post pictures, sorry:: the figure is:
-a circle within a circle. The small inner circle is white, and everything else outside that little circle is shaded. *like a wheel of a car.

In the figure above, what is the maximum number of nonoverlapping regions into which the shaded area can be divded using exactly two straight lines?

A) 3 B) 4 C) 5 D) 6 E) 7

The answer is C) 5, but i have no idea why. I don’t even understand the question

Q4. If p-q=4 and r is the number of integers less than p and greater than q, then which of the following could be true?
I) r=3 II) r=4 III) r=5

A) I only B) II only C) III only D) I and II E) I, II, and III

answer: D) i and ii , again, I don’t get why.
