The article states that the internal combustion engine should be replaced with hydrogen based fuel cell engine in cars and provides three reasons of supports.However, the professor explains that hydrogen based fuel cell engine is not a good option in replacement of internal combustion engine and refute each of the author's reasons.
First, the reading claims that internal combustion engine relies upon petroleum products to works ie: on gasoline or diesel which is a finite source of energy and hydrogen can be derieved from renewable sources and easily available . The professor refutes this point by saying that hydrogen is not easily available in its required form. She states that hydrogen have to be extracted from its sources and have to be converted to liquid form and should be stored in in -200 celsius which is very difficult.
Second, the article posits that internal combustion engine produce pollution by burning of oil which produces pollutant like carbon dioxide and claims that hydrogen fuel cell engine is a good option to eliminate this problem. However, the professor says that to extract pure desired form of hydrogen makes more pollution as this extraction requires burning of coals etc.
Third , the reading says that hydrogen fuel cell engine will be less expensive and twice efficient than internal combustion engine. on the other hand, the professor opposes this point by explaining that there will be no cost saving as fuel cell engines parts need to be made of plantinum which is a very rare and expensive material.

Suggestion: Refer to engines and parts
Sentence: First, the reading claims that internal combustion engine relies upon petroleum products to works ie: on gasoline or diesel which is a finite source of energy and hydrogen can be derieved from renewable sources and easily available .
Error: derieved Suggestion: derived
