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.

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

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 current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
