Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
B. Sharp mental acuity
Mental acuity refers to being mentally sharp. If you're mentally sharp, you have an excellent memory, and you find it easy to complete different tasks. Lack of sleep can effect this.
Odd question...but, uh...if it helps...grab the stick that's in your eye and pull yourself to safety?
This question is an example of the fallacy of correlation and causation.
The fallacy exists due to the fact that human beings like to find cause and effects towards the things that to not exist.
So they have to fabricate patterns that would end up making two different variables and situations to be closely similar.
