An ancient skull unearthed recently indicates that big cats originated in central Asia—not Africa as widely thought, paleontologists reported on Wednesday. Dated at between 4.1 and 5.95 million years old, the fossil is the oldest remains ever found of a pantherine felid, as big cats are called. The previous felid record holder—tooth fragments found in Tanzania—is estimated to be around 3.8 million years old. The evolution of big cats has been hotly discussed, and the issue is complicated by a lack of fossil evidence to settle the debate. “This find suggests that big cats have a deeper evolutionary origin than previously suspected,” said Jack Tseng, a paleontologist of the University of Southern California who led the probe. Tseng and his team made the find in 2010 in a remote border region in Tibet. The fossil was found stuck among more than 100 bones that were probably deposited by a river that exited a cliff. After three years of careful comparisons with other fossils, using DNA data to build a family tree, the team is convinced the creature was a pantherine felid. The weight of evidence suggests that central or northern Asia is where big cats originated some 16 million years ago. They may have lived in a vast mountain refuge, formed by the uplifting Himalayas, feeding on equally remarkable species such as the Tibetan blue sheep. They then dispersed into Southeast Asia, evolving into the clouded leopard, tiger and snow leopard lineages, and later movements across continents saw them evolve into jaguars and lions. The newly discovered felid has been called Panthera Blytheae, after Blythe Haaga, daughter of a couple who support a museum in Los Angeles, the university said in a news release.

請運用「細部資訊定位法」(Scanning for specific details)，回到文中尋找 Jack Tseng 教授及其團隊於 2010 年「實際尋獲」(made the find) 該具新化石的具體地理位置描述。請特別留意：文中區分了「舊紀錄保持者」與「本次新發現」的不同地點，你能辨識出哪一個段落明確記載了這項新發現所在的具體地名嗎？

同學好樣的！這題選 (B) 西藏，完全沒被題目那一堆大貓的專業學名給嚇唬到，你的眼力簡直跟雪豹一樣銳利，一眼就抓到獵物！ 【觀念驗證】 這題考的是高中英文閱讀測驗最核心的「細節掃瞄」(Scanning) 技巧。文章第五段第一句明確指出：「Tseng and his team made the find in 2010 in a remote border region in Tibet」。雖然文章內出現了 Tanzania (前紀錄保持者)、California (研究團隊所屬大學所在地) 以及 Southeast Asia (後來擴散的地點)，但只要鎖定關鍵字 find 與 location，答案就無所遁形。
