Complete Question Explanation
Main Point. The correct answer choice is (D)
The argument begins by establishing that even though the technology to produce hydrogen-powered cars already exists, the fuel-distribution system for these cars does not. The following sentence (“however….”) states that the infrastructure is likely to appear and grow rapidly. Since the final sentence supports the previous one by using an analogy, the conclusion can be found in the third sentence of the argument.
Note the use of the adverb “however” in the beginning of the third sentence. While this word is not an automatic conclusion indicator, it is often used to transition from one idea into another. In many cases, this adverb sets off the main conclusion of the argument. The test will also use words such as “yet” and “but” to achieve this literary transition.
Answer Choice (A): This answer choice reflects the first sentence of the argument. There are no premises given to support this statement, so it is not a conclusion. Rather, this sentence represents background information for the argument.
Answer Choice (B): This statement presents the problem that currently exists with hydrogen-powered cars. This is also background information for the argument. The conclusion, which occurs in the following sentence, claims that this lack of hydrogen fuel stations will likely be overcome in the future.
Answer Choice (C): This answer choice is too broad. The conclusion here was solely about the fuel distribution system for hydrogen-powered cars, not about the development of new technologies generally.
Answer Choice (D): This is the correct answer choice. This is the main conclusion of the argument. The argument concludes that the development of the fuel-distribution system for hydrogen-powered cars is likely to appear and grow rapidly because it is analogous to the development of a fuel distribution system for gasoline-powered cars a century ago.
Answer Choice (E): The author concludes that the hydrogen fuel-distribution system will grow at a rate similar to that experienced by the gasoline fuel-distribution system a century ago. She does not conclude that consumer demand for the two systems will necessarily be similar, however.
