Stimulus

Proponents of the electric car maintain that when the technical problems associated with its battery design are solved, such cars will be widely used and, because they are emission-free, will result in an abatement of the environmental degradation caused by auto emissions. But unless we dam more rivers, the electricity to charge three power sources produces considerable environmental damage. Thus, the electric car _______.

What this question is testing

Most Supported

Your task

Break the argument into its conclusion and evidence, then do exactly what the question stem asks with that structure.

Common trap

Answers that sound relevant to the topic but don't connect to the argument's actual reasoning.

Winning move

Predict what a right answer must do, then test each choice against the conclusion-evidence gap.

Which one of the following most logically completes

Answer choices

  1. Correct53% picked this

    will have worse environmental consequences than its proponents

    Why this is right

    This paraphrases the idea that the proponents of the electric car are wrong, while not going too far into how wrong the they are. It's technically not a great answer. The only environmental consequences we heard about proponents believing were that there would be less environmental damage from auto-emissions. The author doesn't dispute this, but just seems to be warning us that electric cars will still do environmental damage. The fact that this answer is phrased "worse consequences than proponents believe" is a sloppy fit. We're not entirely justified in picking that language, but it's our best available answer choice.

    Skill tested: Most Supported · how this choice captures the argument's function is the move to repeat next time.

  2. Out of Scope2% picked this

    will probably remain less popular than other types

    Popularity is not discussed in the argument.

  3. Unrelated to Goal5% picked this

    requires that purely technical problems be solved before it

    This is a very strong idea that is unrelated to our author saying, "Hey, electric cars are still going to cause considerable environmental damage". It doesn't sound like a conclusion built on the author's premises, which are the two claims after "But". Instead, it's taking the proponents Sufficient idea, "If technical problems solved, then electric car will succeed" and twisting it into a Necessary idea, "In order for electric car to succeed, the technical problems must be solved".

  4. Too Strong5% picked this

    will increase the total level of emissions rather than

    This is assumes that the environmental degradation caused by producing the electricity to charge electric cars would be greater than the degradation caused by auto emissions. That's an even harder comparison to justify than is the comparison in (A). This answer would also imply (E). If the electric car increases emissions, then clearly the electric car did not produce a net reduction in environmental damage. Since (D) and (E) can't both be right, that would tell us that this answer is wrong.

  5. Too Strong35% picked this

    will not produce a net reduction in

    This assumes that the environmental degradation caused by producing the electricity to charge electric cars would be as much or more than the degradation caused by auto emissions. We can't quantify or compare whether the switch to electric cars would still be a net positive or a net negative. The author has merely said that getting the electricity to power these cars will cause considerable damage.
