Q: Article: If you've ever owned a chimney, you know that it can get pretty dirty. There's a whole lot of soot that gets stuck on the inside. That stuff has to get cleaned, or you could have a serious fire risk. While nowadays we have easier ways of doing this dirty job, in the way back days somebody used to climb up the chimney and clean all that soot. And the thing is, not just anybody could do it. You had to be really small to fit up in the chimney, so they used to give the task to kids - some as young as four or five years old. They worked for their boss known as a master-sweep. They were often covered in soot, and were very likely to get burned. They often developed what became known as soot wart, a form of cancer. Are your unfairness bells ringing? William Blake's certainly were. The physical dangers and widespread unfairness of the chimney-sweeping job really stuck in his throat, so much so that he wrote not one, but two poems called "The Chimney Sweeper". The first poem (the one we're discussing here)was published in 1789 in a book called Songs of Innocence. These little poems took children and the joys of childhood innocence as their subject. As you've probably guessed by now, many of the poems in Songs of Innocence, like "The Chimney Sweeper", are about the ways in which childhood innocence is destroyed by unkind old adults. For Blake, innocence is, in many ways, a total joke. It doesn't exist, because it's always taken away by the realistic world - chimney-sweeping, death, poverty, etc. What does a five-year-old chimney sweeper in 18th-century England have to do with you? More than you might think. It is reported that 150 million kids are in child labor in developing countries. Many of them work long hours and face dangerous health risks. Like Blake's chimney sweeper, these kids are not even given a chance at innocence because experience keeps getting in the way.
Answer: Dirty and dangerous.

A: Which of the following can best describe the chimney-sweeping job?

Q: Article: Columbus made four voyages to the west between 1492 and 1504 in his vain search for a sea route to Asia. The mystery of why he failed to find it haunted him and filled him with sadness. Wherever he went to Cuba, Puerto Rico, Jamaica, South America, Panama, down the coast of Central America--it was always the same story. Instead of golden palaces, there were grass huts and palm-leaf tents. Instead of silk-robed merchant princes, he found "Indians" who did not have so much as a shirt on their backs. When Columbus explored the West Indies in 1493,he heard tales of a fierce Indian tribe who literally devoured its defeated enemies after a battle. These people were called by many names in the area, including Calina, Canima, Carib, and Caniba. Columbus recorded the name of the American natives as Canibales in Spanish, a word which came to refer, within a few years, to any eater of human flesh. In the similar fashion, the word Caribbean, a title for the sea as well as for the region, came into English. At times Columbus knew that this new land was not China, not Japan, not the Spice Islands. He seemed to accept it as a part of the earth that the geographers of Europe had never heard of before. It was another world--and he called it exactly that--but Columbus also insisted until he died that land he had reached was an unknown part of Asia.
Answer: Columbus' voyages

Q: Article: We each have a unique genetic (,) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion combinations of DNA which come from the random mixing of your parents' genes. Except for identical twins , no one has the same combination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make. But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters. Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins. Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects _ . We could ask, "Are our lives determined by our genes or our upbringing?" Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.
Answer: To discover what shapes us as individuals.
