Question 18
In a lab, the scientists have been performing tests on pregnant lab rats with caffeine. These rats were given the equivalent amount of caffeine that a person would consume with 6 cups of coffee every day. The caffeine increase also increased the occurrence of birth defects.

If a warning applies only to a small minority of people is inappropriate
Six cups of coffee per day is much higher than what a person typically drinks

Studies on rats don't provide us with much data regarding birth defects in humans
The significance of birth defects due to the use of caffeine is unclear
