Explanation
Correct answer: C.
Choice C is the best answer because it most accurately states the main idea of the text. The text begins by stating that the Black Pearl orchestra performs classical music, and then goes on to explain that the orchestra offers an iConduct! program. According to the text, this program offers community members the opportunity to learn some basics about conducting and then apply what they learn by conducting the orchestra themselves. Thus, the main idea of the text is that community members can both listen to and participate in a classical music performance.
Why the other choices are wrong
Choice A
Choice A is incorrect. Although the text states that the Black Pearl orchestra is based in Philadelphia, it doesn’t indicate that most of the music it plays was composed by Philadelphians.
Choice B
Choice B is incorrect. Although the text does state that Johnson founded the Black Pearl orchestra, this is just a detail and not the main focus of the text. Moreover, while the text does say that the orchestra sometimes plays music by Montgomery, it doesn’t assert that the orchestra was founded solely for the purpose of performing Montgomery’s work.
Choice D
Choice D is incorrect. Although the text explains that community members are invited to conduct the Black Pearl orchestra after participating in the iConduct! program, the text doesn’t indicate that Johnson allows community members to do this for the specific purpose of showing how difficult the task is.
