Number of words – 167 Fewer than half of the American college students who were given this set of drawings and asked to select the correct image could do so.

Number of words – 86 One of my self-imposed rules is, “Don’t criticize unless you can do better.” Try to understand how the faulty design might have occurred: try to determine how it could have been done otherwise.
