6 points are marked on a straight line and another 7 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 most appropriate option:
A) 9	B) 105	C) 196	D) 21	E) 14
assuming that the top line can have either 2 points or 1 point...   6! / 1!5! - 6! / 2! 4! yields 9.   9
