5 points are marked on a straight line and another 6 points are marked on a second straight line with no points in common. How many triangles can be constructed with vertices from among the above points?  Choose the correct choice from the following answers.
A) 91
B) 5
C) 196
D) 21
E) 14
assuming that the top line can have either 2 points or 1 point...   5! / 1!4! - 5! / 2! 3! yields 5.   5
