Well thanks for the responses. Yeah, I thought it was A to. In fact its blatantly obvious its A. The test answer key thinks is B (syllogism) which is incorrect.

The easy logic is just because every 4 door he has seen has 8 cylinders, doesn't mean every 4 door car in existence has 8 cylinders.

The syllogism of this would be "Every 4 door car has 8 cylinders. Every car I fix has 8 cylinders. Therefore, Every car I've fixed has 4 doors."

A generalization is making a statement about the whole by only observing some of its parts. i,e, saying that ALL 4 doors have 8 cylinders just because on the portion you've fixed that was always the case.

This is really ridiculously simple, I don't know why the answer is wrong. Its the same as saying every rectangle I've ever drawn is a square (all sides equal length), so therefore every rectangle is a square. Obviously not true.

I'm going to stick with books from now on and avoid online quizzes.
