Why did the trial represent the changes of the 1920’s?

Explanation:

Scopes Trial:

It made for great oratory between eminent rivals, and it put the debate over teaching evolution on front pages across the country. But one thing the Scopes "monkey trial" of 1925 did not do was settle the contentious issue of evolution in the schools, which continues to incite strong passions and court actions to this day.

Narrowly, the trial was about challenging a newly passed Tennessee state law against teaching evolution or any other theory denying the biblical account of the creation of man. Broadly, the case reflected a collision of traditional views and values with more modern ones: It was a time of evangelism by figures such as Aimee Semple McPherson and Billy Sunday against forces, including jazz, sexual permissiveness, and racy Hollywood movies, which they thought were undermining the authority of the Bible and Christian morals in society.

I believe the correct answer from the choices listed above is option B. Rousseau's ideas of "natural law" led to his publication of The Social Contract in 1763. His writings reflect Enlightenment ideals because he desired  harmony between faith and reason. Hope this answers the question.
