Ex Input:
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.
Answer: it is similar

Ex Output:
Bernard chose silver iodide as a method of cloud seeding because _ .

Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly.
Answer: the living standard of the world's population will improve greatly

Ex Output:
According to the passage, in 2100 while output of food will be greater, _ .

Article: Noah felt like he was always hitting the books. While his friends were meeting for pickup soccer games after school, he was back home in his room reading and rereading the same material. But no matter how hard Noah studied, he had difficulty remembering things and his grades stayed average. Meanwhile, his friend Sean, who never seemed to study, always aced tests. It didn't seem fair. Because Noah was so frustrated , his dad and teachers made an appointment with the school psychologist. She diagnosed Noah with a learning disability. Although Noah felt relieved to know what was going on, he was also worried. He didn't like the "disability" label. And he was concerned about what it might mean for his future. Would he be able to go to college and study engineering as he'd hoped? For someone diagnosed with a learning disability, it can seem scary at first. But a learning disability doesn't have anything to do with a person's intelligence. After all, such successful people as Walt Disney, Alexander Graham Bell, and Winston Churchill all had learning disabilities. Learning disabilities are problems that affect the brain's ability to receive, process, analyze, or store information. These problems can make it difficult for a student to learn as quickly as someone who isn't affected by learning disabilities. The way our brains process information is extremely complex --- it's no wonder things can get messed up sometimes. Take the simple act of looking at a picture, for example: Our brains not only have to form the lines into an image, they also have to recognize what the image stands for, relate that image to other facts stored in our memories, and then store this new information. It's the same thing with speech - we have to recognize the words, interpret the meaning, and figure out the significance of the statement to us. Many of these activities take place in separate parts of the brain, and it's up to our minds to link them all together. If, like Noah, you've been diagnosed with a learning disability, you're not alone. Nearly four million school-age children and teens have learning disabilities, and at least 20% of them have a type of disorder that makes it difficult to focus. No one's exactly sure what causes learning disabilities. But researchers do have some theories as to why they develop.
Answer: encourage him to pick up soccer games

Ex Output:
Noah's dad and his teachers went to see the school psychologist to _ .
