Read the following article and select the best answer. Article: While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted--being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer! About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens. Late last year, the engineer presented a video of his first prototype that begins by creating a single slice of dough that is cooked and printed at the same time. Then comes the tomato "sauce" -- a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn't show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds. While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That's because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not. Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars! Question: NASA offered $ 125, 000 to Anjan Contractor mainly to _ . - create some new type of 3-D printer - attract more companies to work for NASA - help astronauts in space enjoy fresh pizza one day - produce pizza in large quantities to earn great profits
help astronauts in space enjoy fresh pizza one day

Read the following article and select the best answer. Article: A businessman lost his wallet. There was plenty of money in it. So he made a promise, "If someone finds my wallet and returns it to me, I'll give half the money to him." A dustman found the wallet in a dustbin. He sent it back to the loser. But the businessman changed his mind. "There was still a diamond ring in my wallet," said the loser, "I won't give half the money in my wallet to you until you return it to me!" "I've never seen a diamond ring in the wallet," said the dustman. They began to quarrel. The businessman refused to do what he had said. The dustman became angry and took him before a judge. After the judge heard what had happened to them, he said to the businessman, "I'm sure you are an honest man. It's true that you have lost a wallet in which there was a diamond ring. But it's also clear that there is only a lot of money in this wallet. I don't think it's yours. Wait for some time. Perhaps someone will be able to return your wallet to you!" Then the judge turned to the dustman and said, "Take the wallet home. If the loser doesn't go to get it back in three days, it will belong to you!" Question: The wallet the businessman lost _ . - was found in a shop - was sent to the judge - was found in a dustbin - was never to be found

Q: Read the following article and select the best answer. Article: The ancient Olympic Games were held in a sacred valley at Olympia at western Greece. The earliest records of the Games go back to 776 B.C.. These contests were held every four years. They were important to the Greeks. When they took place, all wars were stopped. No one dared to break the truce of Olympic. Criers announced the names of winning athletes everywhere in the land. Artists made statues of them. Poets wrote about the Olympic heroes. The first Olympians raced the length of the stadium at Olympia--about 200 yards. But later other events were added:longer races, broad jumping, the javelin throw, the marathon race, and the discus throw. Then boxing, wrestling and horseback riding were also added. In the beginning, only Greeks competed in the Games. But in later centuries, athletes from other lands joined. In 146 B.C. the Romans conquered Greece. Soon the Games began to change. Under the Romans, they became rougher, wilder, and bloodier. Many professionals took part, which was against the spirit of the Olympics. Finally, Emperor Theodosius of Rome decided that the Olympics were a public danger. He died away with them after the Games of A.D. 392. They had lasted over 1,000 years. Fifteen hundred years passed. Then, in the 1890's, Baron Pierre de Coubertin of France began to interest nations in bringing the Games back. The first modern Olympic Games were held in Athens, Greece, in 1896. They have been held every four years since then, except during the two world wars. Question: The Romans took over the Olympics by _ . - thinking of new games - outrunning the Greeks - having better athletes - defeating the Greeks in battle
A: defeating the Greeks in battle
