Given:
The solution decreased by 
ounces every hour for 5 hours.
Remaining solution at the end of the experiment = 
ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by ounces every hour for 5 hours.
Total decreased amount 
Initial amount = Remining amount + Decreased amount of solution.
Therefore, the initial amount of solution is 18 ounces.

Answer: The study of plant varieties.
Explanation:
This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.
Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.
He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.
