Use the sources to answer the question.

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.

The transition that best connects the sentences to synthesize the information in the passage is:

"In the 19th and 20th centuries, widespread efforts were made to reduce the number of wolves at Yellowstone National Park. Again, grazing herds sharply rose."

This transition provides historical context for the decline in the wolf population and connects it to the resulting increase in grazing herds, while also implying the environmental impact mentioned in source 1.
