Both of the provided materials are discussing Hail prevention for the good of farms using cloud seeding. The author believes this method is effective and names three sheds of evidence for it. The lecture, on the other hand, finds these peices of evidence rather not convincing, and refutes each of the author's points.
First, the reading refers to a labratory environment that the experiment of could seeding resulted in light snow rather than hail. However, the professor opposes this point by stating that in a real world environment, there exists a chance of extinguishing the percipitation over a arid region. In other words, if an area is already short in rain, addition of silver iodide in the coulds above it may cause a unexpected drought. Thus, the corps are still in danger but this time for the lack of water.
Second, the reading avers that the real world test of such a practice proved to be successful in Asia. Nonetheless, the lecturer contends that the asian researchers applied this method in a urban area. This can make a differnece from the situation in US since studies have shown urban areas pollutants can make a favorable condtion for silver iodide to take effects. Thus, we cannot be sure if cloud seeding can be as effective in a not polluted area.
Third, the author describes a local study regarding to this task, that is where cloud seeding reduced hail in a particular area. The lecture refutes this point by saying that all nearby areas of the test enviroment were short on hail during the experiment time as well. Thus, she concludes that this outcome is not a result of cloud seeding, but it is most likely to be related to a general climate change in that region of study.
