题目原文：
Hail—pieces of ice that form and fall from clouds instead of snow or rain—has always been a problem for farmers in some areas of the United States. Hail pellets can fall with great force and destroy crops in the field. Over the last few decades, a method of reducing hail, called "cloud seeding," has been tried. In cloud seeding, the chemical silver iodide is sprayed on storm clouds from an airplane. This makes the clouds produce harmless rain or snow instead of hail. Several pieces of evidence suggest that cloud seeding has been effective in protecting crops from hail. Laboratory experiments Experiments in the laboratory support the idea that cloud seeding is effective. Hail usually forms water vapor that is close to the freezing point However, when experimenters added silver iodide to cold water vapor in the laboratory, they often observed light snow forming instead of hail pellets. Evidence from Asia There is evidence about the effectiveness of cloud seeding from several countries around the world. In some Asian countries, for example, cloud seeding has been successfully used to control precipitation in urban areas. These positive results suggest that cloud seeding should also be effective in protecting fields and farms in the United States. Local studies A few local studies also support the value of cloud seeding. One study conducted in a farming region in the central United States, for example, directly monitored crop damage due to hail. The study found that in an area where cloud seeding was used there was reduced hail damage compared to previous years
The reading passage and the lecture talking about the effectiveness of the cloud seeding in protecting crops from hail which considered very damaging factor to the crops. But the narrator claimed that assessment. Also, he cast a doubt about the three evidences which it mentioned in the reading passage.
First, according to the lab experience the allegation of the script asserts that many experiment done inside the lab supported the concept of adding silver iodide to cold water to get light snow instead of heavy hail pellets. But, the professor opposed that idea by explaining that this experiment could affect in negatively way in real life. Because that will prevent any precipitation of cloud seeding with for instance, snow, rain, and hail. Moreover, will lead to more crops damage due to high drought and lack of water.
Second, evidence from Asia claimed that they successfully used to control precipitation in urban areas and protecting more lands and farms could happen in United States because of cloud seeding. In contrast to the aerator who poses that in Asia weather in urban or cities, they increased the pollution and that will affect the interaction between cloud and seeding chemicals. So, without pollution there is not cloud seeding in United States.
Third, local studies explained that there is reduction in the hail damage when they used the cloud seeding in some farms in the central of U.S comparing to previous years. The lecturer contrivers that by saying that it is nature to decrease the hail in some neighborhood areas and that solely the effective of cloud variation of seed level
