[EX Q]: Article: I must have been about fourteen then, and I put away the incident from my mind with the easy carelessness of youth. But the words, Carl Walter spoke that day, came back to me years later, and ever since have been of great value to me. Carl Walter was my piano teacher. During one of my lessons he asked how much practicing I was doing. I said three or four hours a day. "Do you practice , an hour at a time?" "I try to." "Well, don't," he exclaimed. "When you grow up, time won't come in long stretches. Practice in minutes, whenever you can find them five or ten before school, after lunch, between household tasks. Spread the practice through the day, and piano-playing will become a part of your life." When I was teaching at Columbia, I wanted to write, but class periods, theme-reading, and committee meetings filled my days and evenings. For two years I got practically nothing down on paper, and my excuse was that I had no time. Then I remembered what Carl Walter had said. During the next week I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my astonishment, at the end of the week I had a rather large manuscript ready for revision, later on I wrote novels by the same piecemeal method. Though my teaching schedule had become heavier than ever, in every day there were idle moments which could be caught and put to use. I even took up piano--playing again, finding that the small intervals of the day provided sufficient time for both writing and piano practice. There is an important trick in this time--using formula: you must get into your work quickly. If you have but five minutes for writing, you can't afford to waste four chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task almost instantly when the time comes. Fortunately, rapid concentration is easier than most of us realize. I admit I have never learnt how to let go easily at the end of the five or ten minutes. But life can be counted on to supply interruptions. Carl Walter has had a tremendous influence on my life. To him I owe the discovery that even very short periods of time add up to all useful hours I need, if I plunge in without delay.
Question: Which of the following statements is true?
Options: (A) The writer didn't completely take the teacher's words to heart at first. (B) Carl Walter has had a great influence on the writer's life since he became a student. (C) The writer owes great thanks to his teacher for teaching him to work in long stretches. (D) Rapid concentration is actually more difficult than most people imagine.

[EX Q]: Article: People in cities all over the world shop in supermarkets. When you enter the supermarket, you see shelves full of food. You walk in the aisles, pushing your shopping cart. You probably hear soft, slow music in the supermarket. This kind of music is playing to relax you and make you walk slowly. Thus, you will probably stay longer and buy more food. Where do you go in the supermarket when you first arrive? Many people go to the meat section first. This area of the store has many different kinds of meat. Some kinds are expensive and others are not. Usually, some kinds of meat are on sale. So it has a special low price. The manager of the store knows where the customers usually enter the meat section. The meat on sale is usually at the other end of the section, away from where the customers enter. If you want to buy this specially priced meat, you have to walk by the more expensive meat first. Maybe you will see something that you want to buy before you reach the cheaper, inexpensive meat. Then you will spend more money in the meat section. The diary section sells milk that is low in fat. Some supermarkets sell three different containers of low-fat milk. Each container looks different, but each contains the same product. One says "1% fat", one says "99% fat free" and one says "low-fat" in big letters and "1%"in very small letters. If you look carefully you can see that all the milk has the same amount of fat, and each container is the same size. The prices of all these three should be the same. However, in many stores these three containers of milk would each have a different price. The store will make more money if a customer chooses the milk that costs the most. Most of the food in supermarkets is very attractive. People often stop to look at the products in attractive containers. But remember, many products will say, "Buy me!". Stop and think which ones are the best value for your money.

[EX Q]: Article: The ancient Egyptians appeared to be among the first early civilizations to learn how to grow roses. In 1888, at Hawara in the El Faiyum area of Egypt, two-thousand-year-old roses were found in ancient tombs. The discovery suggested roses were an important part of the complex burial ceremony which took place when an important person died. The roses found in the tombs are thought by modern experts to be the oldest preserved flowers ever found in the world. They must have been cut and dried before flowering so that they would remain undamaged. Over the centuries, the roses had shrunk and became tight balls, but on careful examination it was discovered that the petals themselves were hardly damaged. Egypt's skill in mass-cultivation of roses in early times led to the flowers becoming an important export product. At the height of the Roman Empire, Egypt exported large quantities of roses to the Roman courts. Wealthy Romans loved the beautiful color1s and sweet smells of roses. So the Romans attempted to grow their own roses and they eventually mastered the art of mass cultivation. Egypt then decided to concentrate on growing grain instead of roses, so grain soon took over as the number-one agricultural product of Egypt. Roses were appreciated in other early civilizations too, including Greece and Persia. They are a decorative feature on coins, sculpture, and vases dating back thousands of years. There is also evidence that roses were highly valued by the Chinese who believed that the flowers could be used to help treat a wide range of illnesses, from toothache to skin and chest diseases. In the modern world, the rose has not lost its popularity as the "Queen of Flowers" -- the name given to it by the Greek poetess Sappho. Even today more roses are sold than any other flower. Modern techniques have enabled people to create ever more beautiful roses. Transportation by air makes it possible to grow roses in countries with favorable climates and sell them within twenty-four hours in profitable markets all over the world. Tons of roses are transported this way every week. Roses from Ecuador, a country in northern South America, can be bought in Holland, even though that country itself has a huge rose-growing business.
