Ques: I'm taking a test and have to guess the right answer to the question after the article. 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: The best title for the passage may be " _ ". Options: A: Cloud Seeding B: Artificial Raining C: Weather Changing D: Cloud Gathering
Ans: A

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Ron Meyer is the president and COO of Universal Studios.As one of the most successful business leaders in Hollywood, he heads up Universal Pictures and Universal Parks & Resorts.He's the guy who oversees the production of Multimillion-dollar extravaganzas likeKing KongandCinderella Man. Meyer's story sounds like the plot of one of his motion pictures.He grew up in a modest home where there was little income.It was a big deal to go to a restaurant.At 15, he quit high school and spent his time hanging out with the neighborhood toughs .He was then a kid quick with his fists who seemed to get into fights somewhat regularly.At one point, he was separated from others with an infectious disease, having no TV and nothing to do.His mother sent him two books.One wasThe Amboy Dukes, a novel about kids in street gangs.The other wasThe Flesh Peddlers, about a guy in the talent agency who lived a successful life."I realized," he says, "that I was no longer that silly kid I had been, and I wanted to change my life." Meyer took any job he could get.He worked as a busboy and short-order cook.He cleaned offices and sold shoes.That attitude made an impression on people.One day he received a call from Paul Kohner, a successful agent who represented stars like John Huston, Charles Bronson and Lana Turner.Their messenger and driver had quit, and they knew Ron was willing to take whatever job they offered. He started the job the next day. Meyer was lucky to work with a good boss--and _ .In nearly six years of driving for Kohner, Meyer became his right-hand man and learned a lot.By the 1970s, Meyer had built many relationships in the business.In 1975, the fate presented an opportunity and he started his own operation Creative Artists Agency, which became a huge success, representing Hollywood legends like Barbra Streisand, Tom Hanks and Tom Cruise. Twenty years later, Meyer was appointed to run Universal Studios, a position far beyond his youthful dream.But once he saw success was possible, he was driven to achieve it.Today,... Question: Which of the following is TRUE according to the passage? Options: A: A talent agency is to oversee the production of movies. B: Ron Meyer did far more successfully than Raul Kohner. C: Relationship is the most important thing in the film industry. D: Meyer had never thought of being as successful as today.
Ans: D

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Everyone knows the story of Benjamin Franklin's famous kite experiment. He was a man of many gifts and interests. His natural curiosity about things made him try to find ways to make them work better. Although he made important discoveries, Ben didn't "invent" electricity. He did, however, invent the lightning rod which protected buildings and ships from lightning damage. In America, most people warmed their homes by building a fire in a fireplace even though it was kind of dangerous and used a lot of wood. Ben said that he had another better way. His invented an iron stove which allowed people to warm their home less dangerously and with less wood. The stove that he invented is called a Franklin stove. Ben also set up the first fire company and the first fire insurance company in order to help people live more safely. As the postmaster, Ben had to find out the best way for delivering the mail. He went out riding in his carriage to measure the routes and needed a way to record the miles. He invented a simple _ for it. In his old age, Ben retired from business and public service and wanted to spend his time reading and studying. He found, however, that his old age had made it difficult for him to reach books from the high shelves. Even though he had many grandchildren to help him, he invented a tool called a long arm to reach the high books. The long arm was a long wooden pole with a grasping claw at the end. Later, other famous inventors, like Thomas A. Edison and Alexander Graham Bell, would follow in Ben's footsteps by trying to find ways to help people live better. Today's curious thinkers are keeping Ben's traditions alive by inventing new and improved ways to make things work. Question: Benjamin Franklin invented a long arm in order to _ . Options: A: replace his disabled arm B: play games with his grandchildren C: get books from the bookshelf more easily D: clean and tidy his house and the bookshelf
Ans:
C
