Ethanol fuel

Both the reading passage and the lecture discuss the issue of Ethanol fuel. The reading passage states that Ethanol fuel will become alternative of gasoline, while the lecture casts doubt on the statement put forward in the reading passage.

Initially, the article outlines that ethanol fuel, like gasoline, will product carbon dioxide in the air, which will not ease global warming problem, whilst the lecture argues it, stating that the ethanol fuel is made by plants. When these plants grow, they absorb the carbon dioxide and counteract the effects. 

Furthermore, the author mentions that the production of ethanol fuel will decrease the food for animals. The professor departs from the idea, underscoring that there are lands not responsible for food production, and its land can be used to grow plants for ethanol fuel production..

Lastly, according to the reading passage the price of ethanol fuel is not competing after receiving the tax subsidies from the government, whereas the lecture refutes it highlighting that the price of ethanol fuel will go down as more people use it.

Hence, the lecture questions the reading passage by provided contrasting points to it. The reading passage does not think that ethanol fuel is a replacement for gasoline; in contrast the professor thinks ethanol fuel is promising.
