some think the parks ______ is endangered.
a observatory
b ambiance
c administration

Explanation:

To solve this, we analyze the context. The paragraph talks about people going to national parks to be in nature, and the development of cell phone towers is troubling some as it affects the parks' natural feel.

• Option A "observatory" refers to a place for observation (like astronomical), which doesn't fit the context of the park's natural environment.
• Option B "ambiance" means the atmosphere or mood of a place. The natural, wild atmosphere of the parks is what people seek and what might be endangered by cell phone towers, so this fits.
• Option C "administration" refers to the management of an organization, which is not related to the park's natural environment being affected.

Answer:

B. ambiance
