Directions: You have 20 minutes to plan and write your response. Your response will be judged on the basis of the quality of your writing and on how well your response presents the points in the lecture and their relationship to the reading passage. Typically, an effective response will be 150 to 225 words.
Question: Summarize the points made in the lecture, being sure to explain how they respond to the specific points made in the reading passage.
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.

Integrated Writing
The author discussed that although hail makes crops suffer a lot, there has always been a method called cloud seeding which can protect crops from this disaster. He listed three facts supporting this approach. However, the speaker holds a contradictory view that all these three ways are not reliable.
First, the writer proposes that laboratory experiments has already proved that cloud seeding is effective in eliminating hail. But the professor points out that although the hail can be turned into rain and snow in experimental movement, but it is also possible that hail, snow and rain can be all prevented by cloud seeding. Consequently, it will cause drought. Crops will still be damaged as a result of lack of water. The writer’s first argument is refuted.
Second, the passage indicates that cloud seeding has an Asia evidence. To render this disproof, the lecturer reveals that this successful application in Asia probably will not get a similar outcome in America. High air pollution offers favorable conditions for cloud seeding process because those polluted air can interact with cloud and seeding chemicals. So this method which can be used in cities area may not be effective in unpolluted farming area. The second idea in the passage is also retorted.
Third, the essay says that local studies in central United States also attain a satisfying result. Nevertheless, the speaker rebuts this idea. He thinks it unconvincing because hail damage in whole America not only decreases just in central of America, but also in the east, south and north part of country. So it is hard to say cloud seeding is the exact factor causes all those good things. Natural variation and local weather can also contribute to the elimination of hail disaster. This overturns the writer’s concept. (294 words)
