Q: Read the following article and answer the question. Article: An 18-year-old student was struggling to pay his fees. Not knowing where to get the money, he and a friend decided to host a musical concert to raise money for their education. They went to the great pianist Paderewski. His manager demanded $2,000 for the piano recital . A deal was made and the boys began to work to make the concert a success. The big day arrived. But unfortunately, they hadn't managed to sell enough tickets. The total collection was only $1,600. Disappointed, they went to Paderewski and gave him the entire $1,600, and promised to pay him the rest $400 back as soon as possible. "No," said Paderewski. "Keep the money you need for your fees. And just give me whatever is left." The boys were surprised, and very thankful. Paderewski later became the Prime Minister of Poland, and he was a great leader. When the World War broke out, more than l.5 million people went hungry, but there was no food to feed them. Paderewski turned to the US Food and Relief Administration for help. The head there was a man called Herbert Hoover -- who later became the US President. Hoover agreed to help and quickly shipped tons of food to Poland. Paderewski decided to go across to thank Hoover himself. When Paderewski began to thank Hoover for his kindness, Hoover quickly stopped him and said, "You shouldn't be thanking me, Mr. Prime Minister. You may not remember this, but several years ago, you helped two young students go through college. I was one of them." Question: Why did the two students decide to raise money? Answer:
Answer: To pay for their education.

Q: Read the following article and answer the question. Article: An ly amazing performance! Candy,Please read the story first and chick on the link at the bottom and enjoy! The lady in her 30s was a dancer and was trained since she was a little girl. Later she got into some kind of audient and lost her entire left arm. She was depressed for a few years.Then someone asked her to coach a children's dancing group. From that point on, she realized she could not forget dancing. She still loved to dance.She wanted to dance again.So she started to do some of her old routines. But by her losing an arm,She also lost her balance. It took a while before she could even make simple turns without falling. Eventually she got it. Then she heard some guy in his 20s had lost a 1eg in an accident.This guy also fell into depression and anger. She looked him up and persuaded him to dance with her. He had never danced! "And to dance with one leg ? Are you joking with me? "No way," he replied. But she didn't give up. He reluctantly agreed, "I have nothing else to do anyway."She started to teach him dancing.The two fell down a few times because the guy had no concept of using muscle, controlling his body,and a few other basic things about dancing.When she became frustrated and lost patience with him,he would walk out. Later they got back together again and started training. They hired a choreographer to design routines for them.She would fly high,held by him with both arms, flying in the air. He could bend,supported by one leg and she was leaning on him,etc.They danced beautifully and they beat other students in the competition. I would like to share with you the most magnificent an touching performance I have ever seen! It is a living proof that strong spirit can conquer physical limitations!

Q: Read the following article and answer the question. Article: Cloud seeding is a method of artificially causing clouds to produce precipitation in the form of rain or snow.Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes.The effectiveness of cloud seeding remains controversial .but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production. Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War II.Their work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplane.In this form, the carbon dioxide is called dry ice.On November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground. For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperatures.Their theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vapor.Their theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snow.As the snow reached the warmer temperatures closer to the ground, it melted and became rain. Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide .He used particles of silver iodide because its crystal structure resembled that of ice in clouds.Silver iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature and did not require an airplane as a delivery mechanism.Instead, silver iodide crystals could be fired by cannons high into the air, where wind carried them into the clouds. Question: Bernard chose silver iodide as a method of cloud seeding because _ . Answer:
Answer:
it is similar
