Question

Which of the following is a possible side effect from ingesting too much caffeine, a stimulant used for alertness and endurance?

A. Nervousness

B. Insomnia

C. Shakiness

D. All of the above

Answer 1

D. All of the above because if you think about it logically you can get nervous, have insomnia and shakiness although I don’t know if nervousness is completely true so maybe it is B and C

Answer 2

According to my information, your correct answer may actually be "all of the above" based on the fact that "Insomnia" would be a problem for a person that would be able not to sleep. And therefore, this would arouse nervousness and also shakiness which would then resolve to be "all of the above".
