Identify and explain any fallacies of defective induction or of presumption in the following passages:

My generation was taught about the dangers of social diseases, how they were contracted, and the value of abstinence. Our schools did not teach us about contraception. They did not pass out condoms, as many of today’s schools do. And not one of the girls in any of my classes, not even in college, became pregnant out of wedlock. It wasn’t until people began teaching the children about contraceptives that our problems with pregnancy began.
