Perhaps because of thepopulation spurt, the wolves have begun to stray outside the park's boundaries. In a few cases, they have ventured onto bordering ranch lands and killed domestic livestock.

But some ranchers have taken the law into their own hands and shot the wolves themselves. The ranchers want the legal right to shoot any wolf that ventures onto their property. A. The reintroduction of gray wolves was a bad idea from the beginning. B. The reintroduction of gray wolves into Yellowstone Park proves that endangered animals can be saved by human intervention. C. The 1995 reintroduction of gray wolves into Yellowstone Park has saved them from extinction; however, it has also caused some serious problems.
