The article argues that ethonol fuel is not a good replacement for gasoline by providing several reasons, while the listening material considers those reasons as unconvincing and invalid.
First, according to the lecturer, the use of ethanol fuel will help to solve global warming, one of the environment problems caused by the use of gasoline. When corns and sugar canes, the source of ethanol fuel grown, they absorb carbon dioxide as part of nutrition, which helps to remove carbon dioxide from atmosphere. This contradicts the idea in the passage.
Second, the professor points out the use of ethonol fuel does not necessarily reduce food source for animals. It is possible to make ethanol from cellulose, which is the main opponent for the parts that are not eaten by animals. This point directly contradicts the assertion made in the passage.
Third, although it is true that the present relatively low price of ethanol is because of tax subsides provided by the government, this subsides will not be always needed. In the future, when more people start to buy ethanol, production will increase and finally lead to a drop in prize. According to the data, if the number of customers becomes three times greater, the price will drop 40%. Therefore, the professor contradicts with the idea made in the article.
