4 points are marked on a straight line and another 5 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? Pick:	A) 91	B) 105	C) 196	D) 2	E) 14
assuming that the top line can have either 2 points or 1 point...   4! / 1!3! - 4! / 2! 2! yields 2.   2
