Source 1: When the wolf population in Yellowstone National Park neared zero, the grazing herds rose up to 35,000 animals. When grazing herd numbers rise too high, it can impact the environment negatively.

Source 2: Over 150,000 people from around the world come to Yellowstone National Park each year specifically to see wolves. This brings in nearly $35 million in revenue for the states that support the park.

Which transition best connects the sentences to synthesize the information in the passage?

The best transition to connect the sentences and synthesize the information in the passage is:

A. In the 19th -and 20th -centuries, widespread efforts were made to reduce the number of wolves at Yellowstone National Park. As a result, grazing herds sharply rose.

This option indicates a cause-and-effect relationship, showing that the reduction of wolves directly led to an increase in grazing herds, effectively synthesizing the information from both sources.
