I believe the correct answer is D. Cowboy songs.
Aaron Copland, American composer, used cowboy songs to highlight
the frontier themes in his ballets “Billy the Kid” and “Rodeo”. Since Copland’s
most important ballets are based on American folk material (Billy the Kid
(1938), Rodeo (1942), and Appalachian Spring (1944)), he used cowboy songs and
American folk songs to contribute to the main themes.
Answer: Freedom of form and design, song-like melodies (as well as many chromatic harmonies and discords), dramatic contrasts of dynamics/pitch, and big orchestras (due mainly to brass and the invention of the valve).
This ought to help you.

Not sure if the measures are supposed to be counted (the lines)
Answer:
8. a) WWH WWWH
W = left one whole key
H = left half key
9. The time signature indicates how many counts are in each measure and which type of note will receive one count. The top number is commonly 2, 3, 4, or 6. The bottom number is either 4 or 8. Simple time signatures divide music into groups of 2 and compound divide music into groups of 3.
