Question 2
Lisa and Tom both weigh 160 pounds, and both consumed two beers in the last hour. What can we conclude about their blood alcohol levels?
a. Because they are the same weight, both should have the same blood alcohol levels.
b. Neither will show any evidence of having consumed alcohol, because one hour is plenty of time for a 160 lb. person to metabolize the alcohol contained in two beers.
c. Tom's blood alcohol level will probably be higher than Lisa's, because alcohol is absorbed by fat, and women usually have more fat than men.
d. Lisa's blood alcohol level will probably be higher than Tom's, because alcohol is diluted by muscle, and men usually have more muscle than women.
