Answer:
b. the exponential principle
Explanation:
In sociology, the term exponential principle refers to a theory that states that <u>when a discovery is made and the technology allows it, the uses for this discovery tend to grow in a geometric radio</u>, in other way, the uses grow in a very large rate and <u>they start multiplying very fast.</u>
In this example, the discovery of glass gave birth to lenses, costume jewelry, window panes, and test tubes. We can see that the discovery of glass gave birth to many uses to it such as lenses, costume jewelry, test tubes and other things and <u>suddenly, glass was being used in many different ways and these ways started multiplying themselves</u>. Therefore such developments reflect b. the b. the exponential principle.
