Elizabeth Blackwell was born on February 3, 1821 in Bristol, England. Her father was a rich sugar businessman at the time. Because her parents thought boys and girls should be equal, Elizabeth received the same education as her brothers. In 1832, her father's business was destroyed by fire, so her family moved to New York City. But her father's business there failed. Then in 1837, the family moved to Cincinnati, Ohio. Not long after, her father died. After her father's death, Elizabeth, at the age of 16, had to go to work. When she was 24, she visited her dying friend Mary. Her friend said, "You're young and strong, you should become a doctor." That was nearly impossible for a woman in the middle of the nineteenth century. But she knew this was what she was going to do. After several rejections from medical schools, she finally was accepted by Geneva Medical College. By studying hard, she graduated successfully in 1849. After graduating from medical school, she went to Paris to learn more about medicine. She wanted to be a surgeon, but a serious eye problem forced her to give up the idea. When she returned to America in 1851, she found it difficult to start her own practice because she was a woman. In 1857, Elizabeth and her sister, also a doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides, she also set up the first medical school for women in 1868, where she taught the women students about disease prevention. It was the first time that the idea of preventing disease was taught in a medical school. Elizabeth Blackwell started the British National Health Society in 1871, which helped people learn how to stay healthy. In 1889, Elizabeth Blackwell became the first woman doctor in the United States. Most importantly, she fought for the admission of women to medical colleges. Elizabeth Blackwell died on May 3, 1910, when she was 89.She opened a world of chances for women. She always fought for what was right in all her life. In 1949 the Blackwell... Elizabeth Blackwell could not become a surgeon because _ . A) she was a woman B) she had a serious eye problem C) she went to Paris for further education D) she didn't go to medical school

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. How many methods of cloud seeding are mentioned in the passage? A) three B) two C) one D) four
