次の英文を読み, 設問に答えなさい。 Jaguars had called the American Continents their home since the Ice Age when their ascendents crossed the Bering Land Bridge that once joined what is now Alaska and Russia. They lived in the central mountains of the southwestern United States for hundreds of years until they were almost driven to extinction in the mid- 20th century after hunters shot the last one in the 1960s. Currently, jaguars are found in 19 different countries. Several males have been observed in Arizona and New Mexico over the last 20 years, but breeding pairs have not been seen or reported north of Mexico. Natural reestablishment of them is also unlikely because of urbanization and the U.S.-Mexico border blocking jaguar migration routes. Now, after more than a 50-year absence, conservation scientists are suggesting the jaguar's return to their native environment in a study that outlines what the rewilding effort may look like. The authors of the new paper suggest a suitable area for jaguars spanning 2 million acres from central Arizona to New Mexico. The space would provide a big enough range for 90 to 150 jaguars, the researchers explained. They also argued that bringing jaguars back to the U.S. is crucial to species conservation as they are listed as near-threatened on the IUCN Red List, and reintroduction could also help restore native ecosystems, the Associated Press reports. "The jaguar lived in these mountains long before Americans did. If done
