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

Level Passage : 2:30 Lesson 5 Jet Reading 22 ⑤ Questions: 2:00 Compared to dogs and other pet animals, cats often have lots of freedom. Many owners let their pet cats go outside whenever they want to. But where do they go? Does your cat visit your neighbor's house for extra food? How far from home does your cat actually travel? Cat owners have been wondering about such questions for a long time. 5 To find out where cats go and what they do, researchers decided to track them by putting a GPS (Global Positioning System) device around their neck. It is well known that cats are natural hunters. They often chase and catch *wildlife, such as birds and other small animals. It was therefore believed Hoor war301 that cats may go far from their homes to hunt. However, the research showed some surprising facts about cat *behavior. It seems that most cats 10 don't travel very far from their homes. On average, they move around two houses away. Owners were *relieved to hear this result because it confirmed that their cats do not cross major roads. There was another interesting result. One female cat walked more than 1 kilometer from her home. When the owner checked her GPS data, they discovered that the cat had gone to their old house. It showed that cats remember the past longer and more clearly than we think.(219 words) *wildlife 44 *relieve ~を安心させる *behavior Infogt) A Choose the best options.
