问题     By 1970, according to a World Wildlife Fund report, only about 4,500 tigers survived throughout the world, half of them in India. Mr. Forsters, who followed and counted tiger footprints, estimated that in May 1972 only about 1,800 tigers existed in India. Project Tiger supported by W.W.F. was immediately launched. Nine tiger reserves (保留地) were created, with armed guards protecting them.
    The project provided opportunities for researchers from India and abroad to study tigers in the reserves and gather information about their habits. Studies show that a male tiger may control a hunting territory (领地) of between 10 and 20 square kilometers, depending on its age, size and strength. The territory of a male includes the smaller territories of three or four tigresses. A tiger marks the boundaries of its territory by spraying urine and other bodily liquids on bushes. But it tries to avoid territorial fights, being guided by the sharp body smell of other tigers. Tigers fight to death only when a tigress is defending her young or when a tiger is guarding a tigress from the attentions of other males.
    The popular picture of the tiger is that of a cruel and unconquerable hunter. But studies show that it catches only one of 20 victims it tries to attack.
    Fears have recently developed that Project Tiger has been too successful. It has doubled the tiger population but India’s human population has also grown out of control. Land problem is becoming serious and many rural people feel bitter about the fact that some rich forests are reserved for tigers. A growing number of attacks by tigers on man has added to the hostility.
Studies have shown that______.
选项 A、a tigress never attacks until attacked
B、the tiger is not an efficient hunter as is commonly described
C、a tiger usually fights another tiger to defend its own territory
D、the tigress is not as fierce as the tiger
答案B
解析 第3段第2句说，但研究表明老虎捕捉猎物的成功率仅为1／20，B与之相符。第2段说到老虎一般会避免领土之争，C与之不符，故排除；A、D在原文中并未提及均可排除。
