    TOEFL TPO 36: The lecture raised 3 pieces of criticism toward the passage About Cloud seeding, which is a way to turn harmful hails into beneficial rain or snow.

    First, it refuted the evidence About laboratory Experiment. In the lab, when scientists add silver ioxide to water vapor, snow can be seen forming and falling. The Professor argues that although the method may be effective in controlled conditions in the lab, it might loose its effects in the natural world, where the situation is far more complex and changeable. The risks of carrying out the Approach is also overwhelming, she said. Drought could be caused since the chemical may eliminate the whole precipitation, including the rain that crops Need to flourish.

    Next, she disagreed on the proof from Asia, where the Approach has been successful. She stated, however, conditions in Asian countries and the US are different, and therefore, may result in unsimilliar consequences. Also, since the experiments were done in urban Areas, compounding variables, such as air Pollution, should be taken into consideration. It is claimed that the Pollution interacted with silver ioxide and consequently altered the Outcome.

    Last of all, locals studies are not necessarily convincing. It has been observed that not only where the experiment took place, but also the surrounding Areas had seen a reduce of hailing. This, she argued, is a result of natural Variation instead of manmade changes.

    Next, she disagreed on the proof from Asia, where the Approach has been successful. She stated conditions in Asian countries and the US are different, and may result in different consequences as well. Also, since the experiments took place in urban Areas, other variables such as air pollution, should be taken into consideration. She claimed that the Pollution interacted with silver iodide and altered the Outcome as a result.

    Last of all, local studies are not necessarily convincing. There has been observation that not only where the experiment took place but also the surrounding areas had been affected. She argued that this is a result of natural variation instead of artificial changes.
