The reading and lecture are about effectiveness of cloud seeding method, which is utilized for reducing the amount of hail and protect the ranches from hail. In the reading, three proof which champions possibility of the method. The lecturer proposed questions for each solution and these three explanation may be faulty.

To begin with, the author posits that the silver iodide changed the form of precipitation from hail to steep in the laboratory condition. This specific argument is challenged by the lecturer because the real life circumstances are different from the situation inside the building. The lecturer mentions that the chemical probably confine all precipitation including snow and rain to be dropped on the ground by vaporizing them. Therefore, it will cause another harmful effect by posing drought although it prevents the hail damaging the crops.

Secondly, in the article, it is stated that observation in the Asian countries proved that cloud seeding can be expedient because the method dealt with precipitation well. Nonetheless, the lecturer rebuts this interpretation by stating that pollution which interacts the method in the municipal areas are not available in the rural area. Therefore, the approach may be unsuccessful in the farming section since there is no pollution.

Finally, the author of the article claims that direct examination proved that damage of the precipitation was reduced in the area where cloud seeding was employed. By contrast, the lecturer states that destruction diminished also in the neighboring area on which the chemical was not used, which means the reduction of damage was not caused by the cloud seeding but pleasant climate condition.

The lecturer challenges the evidence which supports the method mentioned in the article by these three ways.
