Q44-46 A radio new story. ?
A lot of people in the United States are coffee drinkers. Over the last few years, a trend has been developing to introduce premium¹ specially² blended coffees known as gourmet³ coffees into the America market. Boston seems to have been the birthplace of this trend. In fact major gourmet coffee merchants from other cities like Seattle, San Francisco, came to Boston where today they are engaged in a kind of coffee war with Boston's merchants. They are all competing for a significant share of the gourmet coffee market. Surprisingly the competition among these leading gourmet coffee businesses will not hurt any of them. Experts predict that the gourmet coffee market in the United States is growing and will continue to grow to the point that gourmet coffee will soon capture a half of what is now a 1.5 million-dollar market and will be an eight million dollar market by 1999. Studies have shown that coffee drinkers who convert⁴ to gourmet coffee seldom go back to the regular brands found in supermarkets. As a result these brands will be the real losers in the gourmet coffee competition.
44. What is the main topic of the new story?
45. What probably leads people to choose gourmet coffees over regular brands?
46. What will probably happen in the future to stores that sell regular brands of coffee? ?

Q47-50 A talk in an art history class. ?
You may remember that a few weeks ago we discussed the question of what photography is. Is it art or is it a method of reproducing⁵ images? Does photograph belong to museum or just in our homes? Today I want to talk about a person who tried to make his professional life an answer to such questions. Alfred Stieglitz went from the United States to Germany to study engineering. While he was there he became interested in photography and began to experiment with his camera. He took pictures under conditions that most photographers considered too difficult. He took them at night, in the rain and of people and objects reflected in windows. When he returned to the United States he continued this revolutionary effort. Stieglitz was the first person to photograph skyscrapers⁶, clouds and views from an airplane. What Stieglitz was trying to do in his photographs was what he tried to do throughout his lifemake photography an art. He thought that photography could be just as beautiful a form of self-expression as painting or drawing. For Stieglitz, his camera was his brush. While many photographers in the late 1800s and early 1900s thought of their work as a reproduction of identical images, Stieglitz saw his as creative art form. He understood the power of the camera to capture the moment. In fact he never retouched his prints or made copies of them. If you are in this class from today, I'm sure you'd say: Well, painters don't normally make extra copies of their paintings, do they?
