According to the writer, cloud seeding, which uses a way of altering the temperature or chemical composition of clouds, looks like a viable solution to large hailstorms that cause significant damage to crops, but it and (처음엔 hailstorm의 안좋은 점을 두가지 언급하는것 같았지만 에세이 흐름상 cloud seeding의 상반되는 의견을 제시하는거 였습니다. 이럴땐 and가 아닌 but 을 사용하셔야 합니다.) has been a major concern for farmers for a long time in the U.S. Meanwhile, the professor in the listening contradicts this.
First, the writer in the reading passage makes claims that not only can the technique that adds silver iodide to moist air, which increases the speed of processing accelerates ice formation, be applied to natural environment, but also prevent large water droplets from falling down, with silver iodide making cloud ice crystals quickly. In contrast, the professor argues that since this experiment has been (실험이 누군가에 의해 시행된것이기에 수동태로 표현합니다.) implemented in lab, it is difficult to predict the weather because of natural characteristics with dynamic activities. In addition, adding silver iodide to moist air can cause disaster damage to farmland.
Secondly, it is said stated (say는 흔한 단어입니다. stated라는 동의어로 바꿔주었습니다.) in the reading that the success in cloud seeding in China such as Shanghai and Beijing indicates that it has a possibility of controlling weather in the U.S. On the the other hand (이 전의 문단에서 contrast라는 단어가 사용되었으므로 다른 단어를 사용하였습니다.) contrary, the professor in the listening maintains that while cloud seeding succeeded in China, it can cause air pollution in China, with air in the U.S also being affected by it.
Lastly, according to the writer, the decrease in the amount of hail in Kansas, in which people has used cloud seeding in order to control weather, is due to their cloud seeding activities. Meanwhile, the professor in the listening says that success in controlling the weather in Kansas is not (not의 위치는 동사 뒤에 옵니다.) due to not cloud seeding, but it is the weather characteristics in Kansas, so it is not related to local cloud seeding.
