Read the following article and select the best answer. Article: Can you imagine living in a house built by recycled waste? Texas home builder Dan Phillips transforms trash into artful treasures, creating beautiful floors with wood pieces, kitchen counters from ivory -colored bones and roofs out of license plates . The fantastic houses which spring from his imagination are made almost entirely of materials which would otherwise have ended up in a garbage area. " People have been doing this for hundreds of thousands of years; using whatever is available to build shelter, " Phillips said."If you think about carefully what could be used, then building materials are everywhere. The thirteen homes he has built so far would fit better in an art museum than the residential streets of Huntsville, a conservative town of about 35 ,000 people. Living in these houses is a bit like living in a roadside attraction."Almost every day, somebody knocks on the door and says ' Is there any way that we could see?' "said Edie Wells, an artist who rents a room in the Bone House.Her home features a stairway made of bones, floors covered in wine corks and beer bottle caps.Wells said visitors are most impressed when they see a bathroom with its walls, floor and ceiling entirely covered with broken mirror pieces. In addition, each house is highly energy efficient with plenty insulation , an on-demand solar hot water heater and a system that can collect and recycle rainwater to clean the toilet and wash clothes. Phillips founded Phoenix Commotion 12 years ago with the aim of creating a new model for sustainable housing.For as little as $ 10,000 it builds affordable homes for single parents, low-income families and artists. The company has used hundreds of tons of construction waste by recycling the materials into habitable buildings. Phillips tries to spread his recycled-house idea by speaking at events across the United States, and by using the Internet to reach out to like-minded individuals.Phillips said: "I'm not going to be saving the world anytime soon.But there needs to be at least some... Question: What do we know about Dan Phillips? - He is serious and hard-working. - He is full of imagination and intelligence. - It didn't take him long to build the houses. - He didn't give speeches in the United States.
He is full of imagination and intelligence.

(Question)
Read the following article and select the best answer. Article: Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind. In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes), the Scandinavians make stockfish and the Arabs dried dates. All foods include water--cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked. Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. Various methods are used, but in general, the fruit is spread out on trays in drying yards in the hot sun. Nowadays most foods are dried mechanically. The method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110degC at entry to about 43degC at exit. This is the usual method for drying such things as vegetables, minced meat, and fish. Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to the climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water. Question: Bacteria which cause food to go bad _ . - cannot live in sunlight - are killed by drying - are in no way dependent on the water contained - have their activity greatly reduced by drying
(Answer)
have their activity greatly reduced by drying

Question: Read the following article and select the best answer. Article: On Nov.18,1995,Itzhak Perlman,the violinist,came on stage to give a concert at Avery Fisher Hall at Lincoln Center in New York City. If you have ever been to a Perlman concert, _ him.He was stricken with polio as a child,and so he has braces on both legs and walks with the aid of two crutches . He walks painfully, yet majestically, until he reaches his chair.Then he sits down,slowly, puts his crutches on the floor, undoes the clasps on his legs,tucks one foot back and extends the other foot forward.Then he bends down and picks up the violin, puts it under his chin,nods to the conductor and proceeds to play. But this time,something went wrong.Just as he fmished the first few bars ,one of the strings on his violin broke.You could hear it snap ---it went off like gunfire across the room.There was no mistaking what that meant.There was no mistaking what he had to do. We figured that he would have to get up,put on the clasps again,pick up the crutches and limp his way off stage-to either find another violin or else find another string for this one.But he didn't.Instead.he waited a moment,closed his eyes and then signaled the conductor to begin again. The orchestra began,and he played from where he had left off.And he played with such passion and such power and such purity as they had never heard before. When he finished, there was an awesome silence in the room.And then people rose and cheered.He smiled,wiped the sweat from this brow, raised his bow to quit us,and then he said in a quiet tone."You know, sometimes it is the artist's task to find out how much music you can still make with what you have left.'' Question: What did the audience feel when Itzhak Perlman finished playing? - Surprised. - Disappointed. - Moved. - Satistied.
Answer:
Moved.
