问题      Most people think of lions as strictly African beasts, but only because they’ve been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that spit from African lions perhaps 100,000 years ago, hang on to an almost impossibly small slice of their former territory.
     India is the proud steward of these 300 or so lions, which live primarily in a 560-square-mile sanctuary (保护区). It took me a year and a half to get a permit to explore the entire Gir Forest---and no time at all to see why these lions became symbols of royalty and greatness. A tiger will hide in the forest unseen, but a lion stands its ground, curious and unafraid---lionhearted. Though they told me in subtle ways when I got too close, Gir’s lions allowed me unique glimpses into their lives during my three months in the forest. It’s odd to think that they are threatened by extinction; Gir has as many lions as it can hold--too many, in fact. With territory in short supply, lions move about near the boundary of the forest and even leave it altogether, often clashing with people. That’s one reason India is creating a second sanctuary. There are other pressing reasons: outbreaks of disease or natural disasters. In 1994a serious disease killed more than a third of Africa’s Serengeti lions a thousand animals--a fate that could easily happen to Gir’s cats. These lions are especially vulnerable to disease because they descend from as few as a dozen individuals. "If you do a DNA test, Asiatic lions actually look like identical twins, "says Stephen O’Brien, a geneticist (基困学家) who has studied them. Yet the dangers are hidden, and you wouldn’t suspect them by watching these lords of the forest. The lions display vitality, and no small measure of charm.
     Though the gentle intimacy of play vanishes when it’s time to eat, meals in Gir are not necessarily frantic affairs. For a mother and her baby lion sharing a deer, or a young male eating an antelope (羚羊), there’s no need to fight for a cut of the kill. The animals they hunt for food are generally smaller in Git than those in Africa, and hunting groups tend to be smaller as well.  
One of the reasons why India is creating a secondary sanctuary for the Asiatic lions is that ______.
选项 A、the present sanctuary is not large enough
B、scientists want to do more research on them
C、they have killed many people
D、the forest is shrinking in size
答案A
解析 细节题 。文章第二段提到，由于目前的保护区不够大，狮子们经常离开保护区，由此可见，目前保护区不够大是印度开辟第二保护区的原因之一。故A项正确。
