▶ Topic :Both the reading passage and the lecture talks about the topic, “ethanol fuel.” Regarding this issue, the lecturer contradicts the writer’s opinion that ethanol fuel does not have much benefits.
First, according to the lecture, the writer’s first idea cannot be validated. As ethanol is made from plants, growing number plants can absorb the carbon dioxide. This point refutes that the ethanol fuel will worsen global warming.
Second, the writer’s idea does not sound convincing to the lecturer. Only the parts of the plants are needed to produce ethanol fuel because it is produced by cellulose, cell wall of the plant. Thus, not much plants are needed to create this fuel. This point also counters the writer’s assertion that the ethanol fuel will decrease the source for food.
Lastly, according to the lecturer, the writer’s idea does not sound convincing. As ethanol fuel becomes more available, the supply will increase. According to this point, the writer’s opinion that the price of ethanol fuel will increase is disputed.
