[FONT="] Bears spend much of their time looking for food, and they are not choosy, gorging on insects, berries, nuts, small mammals, ham sandwiches, and garbage with equal relish. Despite this, the chief natural factor limiting a bear population is the food supply. Dr. Lynn Rogers has found that, contrary to popular belief, so-called garbage bears – those that visit town dumps or campsites – do not lose their ability to forage successfully for wild foods but are simply supplementing their diets with easy pickings. In fact, these enterprising bears grow faster, mature sooner, and reproduce earlier than those that depend only on wild foraging. Rogers has also found that dump-fed bears are the strongest and largest in the population. He and his crew once captured a male bear that weighed in at 611 pounds. But easy living for the bears carries a price: those that stalk garbage dumps are easier targets for hunters and those that visit camps – if not injure – visitors. Some state wildlife agencies capture “nuisance” bears that have become too chummy with people and cast them off to less populated parts of the forest. The removal programmes do not always work; bears released 100 miles or more from their place of capture have reappeared in their old haunts.[/FONT]

[FONT="]Read the following passage and choose the best answers to the questions.[/FONT][FONT="][/FONT]
[FONT="] Swans are among the most beautiful of North American waterfowl and have always enjoyed the admiration and even the protection of bird lovers. Of the six species in the swan genus, only two are native to North America. The trumpeter swan, the largest of the group, breeds in the northern United States and Alaska, and was nearly wipe out during the nineteenth century craze for elaborately feathered hats. The whistling swan, which winters in large flocks on the Chesapeake Bay, has recently been renamed the tundra swan because it breeds and summers on the northernmost tundra regions of the continent.[/FONT]
[FONT="] Recently, populations of mute swans – an exotic species introduced to North America from Europe in the early 1900s – have begun increasing by an alarming 30 to 40 percent annually in some states. Most wildlife biologists today believe the majestic white creatures, with their tendency to destroy a pond’s plant life and drive away native waterfowl, might create havoc on the scale of the gypsy, moth, starling, or English sparrow.[/FONT]
[FONT="] Both native species of swans are wild and require large areas of uninhabited summer ground for nesting and feeding. Mutes, however, semi-domesticated and accustomed to people, can nest in pairs of many as three or four on one small coastal pond, which can burden delicate and environmentally essential brackish ponds.[/FONT]

[FONT="] c. describe swans of North America d. prevent extinction of a swan species[/FONT]
[FONT="]72. According to the passage, the main issue concerning mute swans is that they are _____________.[/FONT]
