I am uncertain about question 28. Here is what I have.
I reread the quote, "at the peak of Luminist development in the 1850s and 1860s, spiritualism in America was extremely widespread."
The author later goes on to say that it was also true, however, that the 1850s and 1860s were a time of trade expansion.
(A) Eliminated because "dominant mode of painting" is unsupported.
(B) Eliminated because it's false. Lane was not interested in spiritualism.
(C) Unsure.
(D) Eliminated because "explain why the development of Luminism is coincided" is unsupported.
(E) Unsure.
Is it because spiritualism is the wrong way to understand Luminism?
