▶ Your Answer :
In the reading passage, there is ample support for the author’s claim that there are a lot of advantages of coal, so using the coal for energy source will continue in the future. However, the professor in the lecture gives several reasons as a rebuttal to the author’s point.
First, the professor contends that the coal is complicated to mine. This is because There is not sufficient amount of coal in the earth’s surface. The coal in the surface is almost exhausted so it is not true that due to their location, coal mining is quite easy. This casts doubt on the reading passage’s claim that the coal is commonly placed close to the earth’s surface, so it is easy to mine without specialized equipment to dig deep.
Second, the professor insists that the coal’s transport is quite expensive. The coal is heavy and bulky. Also, there are several trips to transport by truck and train. These reasons make coal mining’s transport expensive. This counters the reading passage’s claim that the coal mining is cheap to transport. Unlike oil, natural gas and hydrogen, it transports in solid form that causes low risks of accident.
Finally, the professor argues that it is not true that the coal industry creates more job for employees. Most companies tend to focus their efforts on developing labor-saving technology to reduce workers. As a result, the number of employees will be decline in the future. This refutes the reading passage’s suggestion that the workers have more jobs due to coal industry
