TPO 9

The reading and the lecture are both about whether the hydrogen-based engine is better than the internal-combustion engine. While the writer provides seemingly plausible reasons to support the idea, the lecturer cast doubts on them with strong arguments.
As a start, the writer states that the fuel-cell engines use easily available resource; however, the speaker clearly points out the fact that the common form of hydrogen in the water is not able to be used. She further explains that only the pure state of the material is usable, and the pure state is difficult to produce and store. She gives an example about how low the temperature should be to store it.
Second, the article asserts that hydrogen-based engines pollute less, but the lecturer refutes the argument by stating the high pollution that acquiring such energy will generate. She says that we have to burn coal or oil to get them and concludes that the cars will not pollute while the process to make it work will pollute a lot.
Last but not least, the speaker presents the that the fuel-cell engines are expensive by showing the high price of the engine made by platinum, a kind of rare and expensive metal. As a result, the argument made by the reading is a poor-formulated thesis.
