Read the article and select the best answer. Article: My dad loved pennies, especially those with wheat. Those were the pennies he grew up with in Iowa and he didn't have many. When I was a kid, Dad and I would go for walks together. We'd spy coins along the way. Whenever I picked up a penny, he'd ask, "Is it a wheat?" It always thrilled him when we found one of those special coins produced between 1909 and 1958, the year of my birth. He told me he often dreamed of finding coins. "I have that dream too!" I told him. It was our secret connection. Dad died in 2002. One grey day, not long after his death, I was walking down Fifth Avenue and I found myself in front of the oldest church in Manhattan, which my father had been attending. I was greeted in warmly. The song was Dad's favorite, one we'd sung at his funeral. After the service, I walked out, stepped onto the sidewalk--and there was a penny. I picked it up, and sure enough, it was a wheat, a 1944, a year my father was serving on a ship in the South Pacific. Then, wheat pennies began turning up on the sidewalks everywhere. I got most of the important years: his birth year, the war years, the year he met my mom, the year they got married. But, no 1958 penny-my year. The next Sunday, after the service, I was walking up Fifth Avenue and spotted a penny in the middle of the street. It was a busy street, but I risked my safety and got it. A wheat! There was my birthday. _ Question: What does the author mean by the last sentence? Options: A: Dad buried the pennies before passing away. B: Our life is fixed and no one can change it. C: The author thinks 21 pennies is a lot of money. D: The pennies started for father's love from heaven.

Read the article and select the best answer. Article: Plants that live in the rainforest have adapted in amazing ways to several very difficult conditions. This means that the plant has changed something in its "body" or "habits" to make it easier to survive in difficult conditions. There are several conditions they have had to adapted to. First, the soil of the forest floor is shallow. Also, the soil of the rainforest is not very rich, or easy to grow in. Next is the problem of very heavy rain which continues over a large part of the year. Finally, many plants of the rainforest are food for animals that live there. The biggest problem that rainforest plants have to adapt to is the lack of sunlight in the rainforest's lower levels. Plants have adapted to this problem in several ways. Many plants have very large leaves. The large leaf is helpful because it has a bigger surface area. The bigger surface area a leaf has, the more sunlight it can absorb. The canopy trees adapt by growing to be 100 feet tall so that their leaves can grab all available sunlight. Other plants called lianas have adapted by rooting themselves in the soil of the forest floor and growing up the trees until they reach the canopy layer. Still other plants, such as epiphytes, have adapted by growing directly on the trees' trunks and branches in the canopy and understory layers of the rainforest. An adaptation to the large amounts of rainfall that many rainforest plants have is called "drip tips". Their leaves are tapered to a sharp point at the end. This allows water to run off the leaf quickly. There are many other adaptations that rainforest plants have made to their environment. These will be discussed in detail, as we investigate the plants of the rainforest! Question: Which of the following is a difficulty that the rainforest plants have to face? Options: A: Changes in their "body" or "habits". B: Epiphytes that grow on trees' trunks. C: Soil that is not very deep. D: The worsening of the natural environment.

Ques: Read the article and select the best answer. Article: DNA is one of the most important discoveries in science. DNA is the plan for the human being, as a blueprint is the plan for a building. DNA makes a person look the way he does. A person's DNA comes from a mixing of his parents' DNA. That's why a child looks like his parents. But, besides controlling things such as height and hair color, DNA can also give people diseases. Scientists are now studying DNA to cure diseases. In the seventies, scientists developed a process called recombinant or RDNA. Although it sounds difficult to understand, RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so, scientists can create new beings. In doing so, scientists can better understand DNA, especially what parts of DNA do what. After they understand DNA, scientists can begin to cure diseases. Often, the new being created will itself be the cure. Besides curing diseases, RDNA research can also do other things. For example, scientists in Japan have already created "super-trees". Trees help humans, because they take CO2, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. "Super-trees" do this too, but do it much faster. As things such as cars and factories have already put much CO2in the area, "super-trees" are badly needed. Unfortunately, there is a serious danger in RDNA research. Scientists want to create animals to cure old diseases, but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may _ many new powerful diseases. As a result, RDNA research will create many solutions, but it will also create many problems. Question: The following statements are true about RDNA research EXCEPT _ . Options: A: the research has been stopped because the created animals carry viruses B: "super-trees" might be widely planted around the world C: scientists have not completely understood DNA D: RDNA research will benefit human beings a lot
Ans: A

Question: Read the article and select the best answer. Article: One day, a poor boy who was trying to pay his way through school by sending newspapers door to door, was so hungry that he decided to beg for a meal at the next house. However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, "How much do I owe you?" "You don't owe me anything," she replied. "Then I thank you from the bottom of my heart." With these words, Howard Kelly left that house. Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor's clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life. At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman's room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: "Paid in full with a glass of milk, Dr. Howard Kelly." Tear of joy flooded her eyes.
