[EX Q]: 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.

[EX Q]: Article: In the Internet age, speed reading is a necessary and important skill. We skim over articles and e-mails to try to get key words and the main idea of the text. With so much information through our electronic devices  , it would be impossible to get through everything if we read word by word, line by line. However, a new trend calls on people to enjoy reading slowly. A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smartphones. They sit back in comfortable chairs and read in silence for an hour. Unlike typical book clubs, the point of the slow reading club isn't to exchange ideas about certain books, but to get away from electronic devices and read in a quiet, relaxed environment. According to the story, the Wellington book club is just one example of a movement started by book lovers who miss the traditional way of reading. Traditional readers, like Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to understand others. Some of these benefits have been backed up by science. For example, a study of 300 elderly people published by the journal Neurology last year showed that adults who take part in activities that use their brain, such as reading, suffer less memory loss as they get older. Another study published last year in Science showed that reading novels helps people understand others' mental states and beliefs -- a key skill in building relationships. Yet technology has made us less careful readers. Computer and phone screens have changed our reading patterns from the top-to-bottom, left-to-right reading order we traditionally used, to a wild skimming pattern as we hunt for important words and information. Reading text online that has many links to other web pages also leads to weaker comprehension than reading plain text. The Internet may have made us stupider, says British journalist Patrick Kingsley, only half joking. Because of the Internet, he says we have become very good at collecting a wide range of factual tidbits  , but we are also gradually forgetting how to sit back, think and connect all these facts with each other.
