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.
According to the passage, a tiger’s territory ______.
选项 A、expands as the tiger grows up
B、is often defended by tigress
C、remains unchanged
D、is the cause of most fights
答案A
解析 第2段第2句提到，研究表明，一头雄老虎依年龄、体型及力量可以控制10至20公里的狩猎领地，随着老虎的长大，其体型及力量都在增大，其占领的狩猎领地的面积自然也就增大，故A正确。
