Which of the following would you not find in a program symphony? only one movement extra sounds to enhance the mood (like cannons) a very descriptive title instruments imitating nature sounds

In my opinion, the correct answer is A. only one movement. Program symphonies were written during Romanticism, which means that they had preserved the typical, 4-movement symphonic form. As program music, they had some kind of programmatic agenda, that is a story they wanted to tell, or a nature scene they wanted to depict, with all kinds of effects imitating forces of nature. The most famous examples include Beethoven's Symphony No. 6 (also known as "Pastoral Symphony"), Berlioz' "Symphonie fantastique", Tchaikovsky's Symphony No. 1 ("Winter Dreams").

Of course, there are also programmatic symphonic poems, which only have one movement - but they are not symphonies.

Iwould go with write exactly two extra paragraphs to point out additional information. but the keyword "exactly" throws me off. leads me to believe it's d. go with your gut feeling. either "write exactly two extra paragraphs" or "none of these".

It does not have a picture if you can add that let me know.
