Question:Question: Summarise the points made in the lecture, being sure to explain how they cast doubt on specific points made in the reading passage.the author in the reading claims that ethanol is not a good replacement for gasoline, whereas the professor in the lecture holds a virtually contrasting perspective and believes that ethanol is a good replacement of gasoline.
the first concern of the reading is that the increase use of ethanolfuel will not get environment improved compare with using gasoline fuel because ethanol also release carbon dioxide into atmosphere when it is burned. The levturer,however,cast doubt on it by stating that ethanol fuel is a environment-friendly fuel. According to the lecturer, when crops are growing, they would absorb amount of carbon dioxide from the air. This directly contradicts what is stated in the reading.
Secondly, the reading furthermantains that the production of ethanol fuel will reduce the amount of plant avilable for uses other fuel, while the lecturer offers an alternative interpretation that ethanol production will not reduce the food sources for animals, specifically, livesstucks only eat part of the crops which will not be used in ethanol fuel production. According, the lecture challenges what is demonstrated in the reading.
the last point of the passage expressed previously is that ethanol fuel doesnot have any price advantage compared with gasoline; the professor,nevertheless, asserts that ethanol will be able to gain a price advantage as if the production getting bigger. he indicates that as the consumption grow, the ethanol production will get bigger and the price of this kind of fuel will be declined in the future.
