Stimulus

As part of a project to enhance the downtown area, the transit authority plans to build a majestic new subway station on the Longview line. However, the current design of the station does not include a connection to the nearby Waterfront line. Adding a tunnel from the station to the Waterfront line a more modest station should be built so that a tunnel can be included.

Which one of the following principles, if valid, most helps to justify the reasoning in

Answer choices

  1. Weak Impact4% picked this

    The transit authority should design a subway station that costs less than

    While the author's proposal of "more modest station w/ tunnel" would presumably stay within budget, so too could a plan where we just build the majestic station w/o the tunnel. So this answer isn't guiding us to pick the author's option over the current design w/o a tunnel.

  2. Weak Impact5% picked this

    The transit authority should consider all potential additions to the subway station that would make it

    The author's proposal of a more modest station with a tunnel connected is a "potential addition that would make it more convenient to commuters". But this answer is merely saying, "we should consider it". That's not a strong push in the direction of, "we should build the modest station w/ a tunnel".

  3. Correct88% picked this

    In the enhancement of the downtown area, convenience to commuters should be given priority

    Why this is right

    This Weighs the Tradeoffs in the way that favors the author's conclusion. The current design wins in terms of majesty. The author's plan wins in terms of commuter convenience. This new station is part of a project to enhance the downtown area. So according to this rule, we should give higher priority to convenience, and thus according to this rule, we should favor the author's plan over the current design.

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

  4. Bad Conclusion Match3% picked this

    Unless a subway station can be built within budget that is both convenient to commuters and in keeping with the new design, the transit

    This is a rule that would allow us to conclude "should abandon plans to build any station". The author doesn't want that. She's trying to convince us to build a station, just a more modest one than the current design.

  5. Unclear Impact0% picked this

    The new subway station should enhance the downtown area more than any other potential project that

    This Weighs the Tradeoffs in the way that doesn't clearly favor either plan over the other. The current design wins in terms of majesty. The author's plan wins in terms of commuter convenience. We aren't told that either of them wins in terms of "enhancing the downtown area more". So going by this rule, we wouldn't know whether to lean towards the current design or towards the author's more modest proposal.
