You are given the following relationships:

. . . . .P > R

. . . . .Q > S

. . . . .P < Q

. . . . .R < S

Since Q > P and P > R, then Q > P > R. Since S > R and P > R, and since Q > P > R, then you have three of four that are greater than R. So which must be the least?

Since Q > P > R and Q > S > R, then Q is shown as being greater than three of four. Which much be the greatest?

Is there any way to tell which of P and S is the greater?
