Part 2


Questions 9-18


·Read the following passage and answer questions 9-18.
1. When Christopher Columbus landed on America’s shores, he encountered copper-shinned people whom he promptly called "Indians". Current estimates indicate that there were over a million Indians inhabiting North American then. There are approximately 800,000 Indians today, of whom about 250, 000 live on reservations.
2. The early settlers had an amicable relationship with Indians, who shared their knowledge about hunting, fishing, and farming with their uninvited guests. The stereotyped stealthy, wicked Indian of western movies are created by different faithless white man; the Indian was born friendly.
3. Disgust developed between the Indians and the settlers, whose encroachment on Indian lands provoked an era of turbulence. As early as 1745, Indian tribes joined together to drive the French off their land. The French and Indian war did not end until 1763. The Indian had succeeded in destroying most of the settlements. The British, superficially submissive to the Indiana, promised that further migrations west would not extend beyond a specified boundary.
4. Vacated from their lands or, worse still, frankly giving their property to the whites for few baubles, Indians were ruthlessly pushed west. The battle in 1876 at Little Horn river in Montana, in which setting Bull and the Sioux tribes massacred General Custer’s cavalry, caused the whites intensify their campaign against the Redman. The battle at Wound Knee, South Dakota, in 1890 put an end to the last vestige of hope for amity between Indians and whites.
5. Although the Bureau of lndian affairs has operated since 1842, presumably for the purpose of guarding Indians "interests", Indian on reservations lead notoriously deprived lives. In recent times Indians have taken a militant stand and appealed to the courts and the American people to improve their substandard living conditions.
