Question

Read the claim about caffeine.

Caffeine improves mental alertness and motor coordination. A university research study was conducted to examine how moderate doses of caffeine affect fine motor skills. Ten teen girls, ages 14 to 18, were given 200 mg of caffeine per day for 30 days. Thirty minutes after taking the caffeine, each subject took a timed fine motor skills test in which they fitted 20 small beads onto pegs. The graph compares each subject’s average results on the same test done 30 minutes before and after taking the caffeine.



Which group would most benefit from the claim?

people who sell coffee with caffeine
people who sell decaffeinated tea
diners that serve only drinks without caffeine
manufacturers of caffeine-free bottled fruit juice

Answer 1

People who sell coffee with caffeine.

Reason: The claim supports using caffeinated beverages, so sellers of caffeinated coffee could use it to promote and increase sales; the other groups sell caffeine-free products and would not benefit.
