听力原文：

    Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. (5) Continuous fighting in the region has made surveys difficult.

    (6) But scientists released a report Monday documenting, with hard evidence, the discovery of “lost lions”.

    A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in the National Park in northwest Ethiopia, on the Ethiopia-Sudan border. (7) The researchers set out six camera traps capturing images of lions, and they identified lion tracks.

    The scientists concluded that lions are also likely to live in the neighbouring National Park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.

7. What did the researchers find in the National Park?

解析：B。本题为细节题。问题为：研究人员在国家公园发现了什么？根据原文“The researchers set out six camera traps capturing images of lions, and they identified lion tracks.”，可知研究人员架设了六处相机陷阱，用来捕捉狮子图像，并发现了狮子踪迹。选线B) Lions’ tracks 与原文一致，其他选项干扰性较弱，题目简单。
