1-26-99: This question from Marlene Goldman at Harvard's School of Public Health was one of several that Prof. Goldman used to involve students in her lectures. She put the question on an overhead, asked students to select their own answer and discuss it with students seated nearby briefly. A show of hands gave her an idea of how many picked each answer and how many changed their minds as a result of the brief discussion. Then she explained the target answer.
