1. Art that explores inner feelings of conflict and unrest is referred to as B. expressionism.
Expressionism is a type of art that deals with the artist expressing his or her feelings and thoughts. So if the artist is feeling conflict or unrest, he or she is going to express themselves via their art, be it painting, music, film, etc.

2. Vaslav Nijinsky is the A. choreographer who created the dance to accompany Stravinsky's The Rite of Spring.
Nijinsky was a famous ballet dancer and a choreographer. He thought of many dances in his life, but probably one of his most famous ones is the one for The Rite of Spring. He is considered to be the best male dancer of the 20th century.

3. At various times in his life, Stravinsky was a citizen of all of the following except C. Germany.
Although he did live in Germany, it was for a short period of 2 months, and he stayed there with a friend. On the other hand, he spent a considerable amount of time in the US, France, and Russia, where he lived for years.

4. The form of Pierrot Lunaire is C. strophic.
Although I am not completely sure about this one, C is the answer I'd pick personally. This composition consists of many strophes, or sections of movements, which is why I'd say that it is strophic, rather than the remaining options.

5. Bartok's primary instrument was the A. piano.
If you look up this composer and musician, you will say that it says he was a famous pianist. That is why I presume his main instrument was the piano, although he was well-versed with other instruments as well, however, the piano was his favorite.
