The lecturer clearly illustrates that the hydrogen is not the solutions to supplant the oil, which strongly casts doubt upon what the reading passage talks about.

Firstly, the professor uses to challenge what the reading illustrates is hydrogen is not such a practical and easily available substances. It must be obtained the pure liquid state and kept very cold to store in the engine.

The second aspect demonstrated in the lecture which can be viewed as another item of contradictory evidence against the reading that the process of manufacture hydrogen will contaminate the environment. In order to purify it, the process need lots of energy by burning the coal and oil.

In addition, contrary to the information shown in the reading passage, the professor makes a fairly different idea that producing fuel-cell engine is extremely expensive. The material which uses to make the chemical reaction is quite rare metal.

In a word, what the speaker illustrates in the lecture is entirely contradictory to the information demonstrated by the writer.
