Questions 61 to 65 are based on the following
passage.
The giant panda, the creature that has become a symbol of conservation, is facing extinction. The major reason is loss of habitat, which has continued despite the establishment, since 1963, of 14 panda reserves. Deforestation, mainly carried out by farmers clearing land to make way for fields as they move higher into the mountains, has drastically contracted the mammal's range. The panda has disappeared from much of central and eastern China, and is now restricted to the eastern flank of the Himalayas in Sichuan and Gansu provinces, and the Qinling Mountains in Shanxi province. Fewer than 1,400 of the animals are believed to remain in the wild.
Satellite imagery has shown the seriousness of the situation ; almost half of the panda's habitat has been destroyed or degraded since 1975. Worse, the surviving panda population has also become fragmented; a combination of satellite imagery and ground surveys reveals panda "islands" in patches of forest separated by cleared land. The population of these islands, ranging from fewer than ten to more than 50 pandas, has become isolated because the animals are unwilling to cross open areas. Just putting a road through a panda habitat may be enough to split a population in two.
