Which word best describes the style of these lines from a novel?

blodgett college is on the edge of minneapolis. it is a bulwark of sound religion. it is still combating the recent heresies of voltaire, darwin, and robert ingersoll. pious families in minnesota, iowa, wisconsin, the dakotas send their children thither, and blodgett protects them from the wickedness of the universities. but it secretes friendly girls, young men who sing, and one lady instructress who really likes milton and carlyle.

ironic
grim
analytical
solemn

I would say that the word that best describes the style of these lines from Main Street, by Sinclair Lewis, is the third one: analytical.

Explanation:

In this excerpt, the author explains the methods of the Blodgett College. The speaker analizes with reasoning thoughts the characteristics of this place, tells the audience that it is "a bulwark of sound religion", and that is "still combating the recent heresies of Voltaire, Darwin, and Robert Ingersoll". The author gives details about the Blodgett and interprets them in this paragraph, that is why I chose analytical as the word to describe it.
