Read the following passage first. Then use the passage and the graphic timeline to answer the questions.

Question

Yellowstone National Park is a large wilderness area located mostly in the state of Wyoming. It is a national park protected by federal law. It was established in 1872, but at that time, hunting was allowed in the park. Wolves were overhunted almost to extinction, and this caused tremendous harm to the ecosystem. Even though the wolves were only one species, their absence had a much bigger impact on the whole ecosystem than most people had predicted. The elk population grew much too large because the wolves weren't there to hunt them. The elk overgrazed many plants and also damaged the riverbank. The absence of the wolves even affected the populations of birds, insects, fish, and beavers. Conservation experts and scientists eventually convinced government officials to bring wolves back into Yellowstone National Park.

The claim you could support is: Wolves serve as a keystone species in Yellowstone.

Question 3

c. At which position on the following timeline would you place this new information?

Without the visual graphic timeline, I cannot provide a specific position (A, B, C, or D). However, based on the passage context, you would place the new information about the reintroduction of wolves leading to a decrease in the elk population and stabilization of other populations after the wolf reintroduction date, which is 1995. Therefore, it could potentially be placed at point D if D represents events after 1995.

Please review the graphic timeline to confirm the correct placement.
