Question: Article: I was born in Tuckahoe,Talbot Country,Maryland. I have no accurate knowledge of my age,never having seen any record containing it. By far the larger part of the slaves know as little of their ages as horses know of theirs,and it is the wish of most masters within my knowledge to keep their slaves thus ignorant .I do not remember having ever met a slave who could tell of his birthday. They seldom come nearer to _ than plantingtime,harvesting,springtime,or falltime. A lack of information concerning my own was a source of unhappiness to me even during childhood. The white children could tell their ages,but I could not tell. Why the same right ought to be taken away from me!I was not allowed to ask my master about it. He considered all such questions on the part of a slave improper and impolite. The nearest estimate I can live makes me now between twentyseven and twentyeight years of age. I come to this,from hearing my master say,some time during 1835,I was about seventeen years old. My mother was named Harriet Bailey. She was the daughter of Isaac and Betsey Bailey,both colored,and quite dark. My father was a white man. The opinion was also whispered that my master was my father;but of the correctness of this opinion,I know nothing and I have no means to know. My mother and I were separated when I was but an infant--before I knew her as my mother. It is a common custom,in the part of Maryland from which I ran away,to part children from their mothers at a very early age. Frequently,before the child has reached its twelfth month,its mother is taken from it,and hired out on some farm a considerable distance off,and the child is placed under the care of an older woman,too old for field labor.

Question: Article: The first day my new teacher walked into our school in Spanish Harlem, I burst out laughing. Ron Clark was a young white guy from North Carolina who talked with a funny Southern accent . He said he used to be a singing waiter. I thought, who is this guy? He's a complete joke. It was 1999 and I was in the fifth grade at New York City's P.S. 83. _ . I'd always been a troublemaker. I'd get yelled at, and then the teachers would give up on me. I thought that's what would happen with Ron Clark. I was wrong. That first week, I kept mocking him. He pulled me out to the hallway and said I'd better shape up. "Tamara," he said, "you're a smart kid. You can do better." He told me I was a natural leader and that I'd go far in life if I started applying myself. I was mad at first, but then something happened: I began to respect him. There were 29 students in our class, and it didn't take long for us to realize that Ron Clark was no ordinary teacher. He was only 27 and had the most unusual way of teaching. To help us learn the states and capitals, he changed the lyrics of a popular rap hit called "Thong Song" and had us sing and dance with him. When we read the Harry Potter books, he decorated our classroom like Hogwarts. And during the Presidential election, he put campaign posters on the walls and covered the room with 5,000 red, white and blue stars.

Options: (A) Excited. (B) Disappointed. (C) Appreciative. (D) Disdainful .

Question: Article: Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a _ . At first, Eijkman thought some kind of germ caused beri-beri. He raised some chickens. He didn't eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate -- refined white rice . When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery -- that some things in food could prevent disease. These things were named vitamins . The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person's food. Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don't, they can also take vitamin pills.
