Question

consider this claim:
the federal government should protect national parks by limiting the number of visitors allowed.
which is the strongest evidence to support the claim?
staff at yosemite national park report that an increase in visitors has led to problems such as smog and trail erosion.
one recent visitor to a national park posted the following review on a popular website: \the experience was disturbing. it was like going to an amusement park: long lines, tons of traffic, trash strewn everywhere.\
in recent years, the national park service has reported a backlog of underfunded projects due to aging infrastructure, budget restraints, and staffing shortages.

Explanation:

The claim is about protecting national parks by limiting visitors. The first option provides evidence from park staff (a reliable source) about specific negative impacts (smog, trail erosion) caused by increased visitors, directly relating to the need for protection. The second option is a single visitor's subjective experience. The third option talks about underfunded projects due to other factors (aging infrastructure, budget, staffing) not directly about visitor - related harm.

Answer:

Staff at Yosemite National Park report that an increase in visitors has led to problems such as smog and trail erosion.
