If t > a and L < a, which of the following cannot be true?  Choices:
A) d + L = 14
B) d - L = 7
C) d - L = 1
D) a - t = 9
E) a + d = 9
Is the answer D?   If t&gt;a, then t-a&gt;0 (always positive). The converse would be a-t&lt;0 (always negative). Option a - t = 9 states that a-t=9, which can never be true.
