There was one shop in the town of Mufulira which was widely known for its racial discrimination. It was a drugstore .While Europeans were served at the counter ,a long line of Africans queued at the window and often not only were kept waiting but were treated rudely by the shop assistants .One day I was determined to make a public protest against this kind of thing ,and many of the schoolboys in my class followed me to the store. I simply went into the shop and asked the manager politely for some medicine. As soon as he saw me standing in the place where only European customers were allowed to stand ,he shouted at me in a bastard language which is only used by a boss when speaking to his servants .I stood at the counter and politely requested in proper English that I should be served .The manager became angry and said , "Even if you stand till Christmas ,I will never serve you ." I went to the District Commissioner's office .Fortunately ,he was out ,for _ however ,I saw a young District Officer who was a friend of mine .He was very concerned to hear my story and told me that all I had to do was come to him personally and he would buy my medicine for me .I protested that that was not good enough .I asked him to accompany me back to the store and to make a protest to the manager .This he did ,and I well remember him saying to the manager , "Here is Mr. Kaunda who is a responsible member of the Urban Advisory Council, and you treat him like a common servant ." The manager of the drugstore apologized and said , "If only he had introduced himself and explained who he was ,then ,of course ,I should have given him proper service." I had to explain once again that he had missed my point .Why should I have to introduce myself every time I went into a store...any more than I should have to buy my medicine by going to a European friend ? I want to prove that any man of any color ,whatever his position ,should have the right to go into any shop and buy what he wanted .After all, the money which I paid across the...

C) He thought he was educated and should be treated differently. D) He thought ,being an important person ,he should not be kept waiting.

At dawn on Friday, May 19, 1780, farmers in New England stopped to wonder at the pink color of the sun. By noon the sky had darkened to midnight blackness, causing Americans, still in the painful struggle of a prolonged war of independence, to light candles and tremble at thoughts of the Last Judgment. As the birds quieted and no storm accompanied the darkness, men and women crowded into churches, where one minister commented that "The people were very attentive." John Greenleaf Whittier later wrote that "Men prayed, and women wept; all ears grew sharp . . ." A recent study of researchers, led by Richard Guyette from the University of Missouri's Tree Ring Laboratory, has shown that vast forest fires in the Algonquin Highlands of southern Ontario and elsewhere in Canada brought this event upon New England. The scientists have discovered "fire scars" on the rings for that year, left when the heat of a wildfire has killed a part of a tree's cambium . Evidence collected also points to a drought that year. An easterly wind and low barometric pressure helped force smoke into the upper atmosphere. "The record fits pretty close," says Guyette. "We had the right fuel, the drought. The conditions were all there." Lacking the ability to communicate quickly over long distances, Americans in 1780 remained in the dark about the event, which had disappeared by the next day. Over the next several months, the papers carried heated debates about what brought the darkness. Some were the voices of angry prediction, such as one Massachusetts farmer who wrote, "Oh! Backsliding New-England, attend now to the things which belong to your peace before they are forever hid from your eyes." Others gave different answers. One stated that a "flaming star" had passed between the earth and the sun. Ash, argued another commentator. The debate, carried on throughout New England, where there were no scientific journals or academies yet, reflected an unfolding culture of scientific enquiry already sweeping the Western world, a revolution... What can be the best title for the text? A) New England's dark day. B) Voices of angry prediction. C) There is no smoke without fire. D) Tree rings and scientific discovery.

Q: Elephants have four distinct personalities that help their herd survive in the African bush, scientists have found. With their grey skin, mournful eyes and slow heavy pace, you could be forgiven for thinking elephants are uniformly melancholy creatures. But scientists have now discovered the largest living land animals have personalities to match their size. In a new study of African elephants, researchers have identified four distinct characters that are common in a herd - the leaders, the gentle giants, the playful rogues and the reliable plodders . Each of the types has developed to help the giant mammals survive in their harsh environment and is almost unique in the animal kingdom, according to the scientists. Professor Phyllis Lee and her colleague Cynthia Moss studied a herd of elephants in the Amboseli National Park in Kenya known as the EB family -- famous for their matriarch Echo before she died in 2009. Using data collected over 38 years of watching this group, the researchers analyzed them for 26 types of behavior and found four personality features tended to emerge. The strongest personality to emerge was that of the leader. Unlike other animals, where leadership tends to be won by the most dominant and aggressive individual, the elephants instead respected intelligence and problem solving in their leader. Echo, the matriarch and oldest in the group, her daughter Enid, and Ella, the second oldest female, all emerged as leaders. The playful elephants tended to be younger but were more curious and active. Eudora, a 40-year-old female in the herd, seemed to be the most playful, consistently showing this feature throughout her life while playfulness in some of the other elephants declined with age. Gentle elephants, which included two 27-year-old females Eleanor and Eliot, touched and rubbed against others more than the others. Those that were reliable tended to be those that were most consistent at making good decisions, helped to care for infants in the herd and were calm when faced with threats.... From the passage we get to know that _ . A) the researchers reached their conclusion by analyzing the data B) the research centered on the 26 types of behavior of the matriarch C) the scientists conducted the research by comparing elephants with other animals D) professor Phyllis Lee and her colleague spent nearly 38 years tracking the herd
