Answer choices

  1. A
    Future electrical needs will Remaining source text redacted.
    Why choice A is not credited
    Incorrect. If the stimulus established that there was no potential location for the creation of this natural gas station, then this answer might be supported. However, the stimulus only established that there aren't currently any locations fit for the station, so this answer is unsupported.
  2. B
    If a new natural-gas-powered Remaining source text redacted.
    Why choice B is not credited
    Incorrect. The stimulus only discusses opposition on the part of residents, not relocation.
  3. C
    No site would be Remaining source text redacted.
    Why choice C matches the stem
    Correct. Argument or Facts:
    Facts

    Question Type:
    Must Be True

    Stimulus Summary:
    Requirements for station: Located close to 1) natural gas pipeline, 2) large body of water, 3) transmission lines; and not opposed by citizens. Located close to 3 isn't a problem, but 1 and 2 overlap only where citizens will oppose construction.

    Answer Anticipation:
    The stimulus sets out a long list of requirements for the new natural-gas-powered electrical generation station. One of the requirements (transmission lines) is stated to not be a problem throughout the country, but there are currently no locations that conform to the rest of the requirements. Namely, there are no locations where natural gas pipelines by water are in areas that citizens wouldn't oppose construction.

    Since the stimulus establishes that there currently aren't any places that meet the requirements, the correct answer will likely reflect that inference—there are no acceptable locations unless something changes. And looking at the list of requirements, it's much more likely that the answer will focus on the construction of new natural gas pipelines, since you can't generally create new large bodies of water and the stimulus establishes that residents "would oppose" construction near the bodies of water the current pipelines run by.

    Answer Explanation:
    This answer highlights that there are no currently acceptable locations, but that there might be if new pipelines are built. This reflects the stimulus, where the current locations don't meet the requirements, but there's no note that new construction couldn't change that.

    Key Takeaway:
    Two takeaways. First, if there are no options that meet all requirements, then there's no option that works.

    Second, if there's no option that works, that doesn't mean there's no option that could work if some other changes are made. Don't get locked into a present-to-future flaw—just because something is true doesn't mean it will continue to be true (unless that's established by the argument).
  4. D
    There currently is no Remaining source text redacted.
    Why choice D is not credited
    Incorrect. The stimulus sets out requirements for any new station, not the existing ones, so this answer is unsupported. The requirements for the new stations might be different from the requirements applied when the old plants were constructed.
  5. E
    Many residents who would Remaining source text redacted.
    Why choice E is not credited
    Incorrect. There's no information that would allow us to make further inferences about what the residents would and would not protest outside of the new generation station.
