Caffeine improves mental alertness and motor coordination. a university research study was conducted to examine how caffeine affects 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 groups would most benefit from the claim? check all that apply.

people who sell coffee with caffeine
people who sell decaffeinated tea
diners that serve coffee with caffeine
soda manufacturers that sell caffeinated drinks
manufacturers of caffeine-free bottled fruit juice
manufacturers of caffeinated energy sports drinks

Scientific explanation is aimed at shedding light into natural phenomenon through the use of measurement results and observations

The groups to benefit from the claim are;

The above selection are correct due to the following reasons:

The claim in the question is: "Caffeine improves mental alertness and motor coordination"

The assertions of the claim are;

1) Caffeine improves mental alertness, meaning that by taking caffeine, a person becomes more alert and/or aware of the environment as well as being able to keep up better at task, which are desirable for work related activities

2) Caffeine improves motor coordination; Motor coordination refers to the ability to involve multiple parts of the body to achieve complex motion. The ability to improve motor coordination can create demand for caffeine among active people

Based on the above association of caffeine to benefits that are desired by active people, (working people that generate income), the groups that would benefit most from the claim are, the dealers in caffeinated products including;

1) People who sell coffee with caffeine

2) Diners that serve coffee with caffeine

3) Soda manufacturers that sell caffeinated drinks

4) Manufactures of caffeinated energy sports drink

Explanation:

Caffeiene is a psychoactive drug that is known for its mental alertness effect.  It is a stimulant that at present has a high level of consumption in the world.

The result of this research justifies the claim that the consumption of caffeine have a positive effect on mental alertness and motor coordination. The outcome would cause a drastic increase in the rate of consumption of caffeine, increasing the demand of caffeined products. Therefore any drink or coffee containing caffeine would witness high demand, which it be a great benefit to those involved in the caffeined product business.
