Answer choices

  1. Too Weak12% picked this

    The factory at which the new welding process was first introduced has had several problems

    The only thing we care about is whether or not this proposed new welding process has been used safely for more than a year at another factory. If it hasn't, then we've proven the conclusion (i.e. justified the application). This is leaning a bit in that direction, because "this new welding process has been problematic at one factory" is heading in the direction of "this new welding process has not been used safety for more than a year at any other factory". But this is nowhere near strong enough to convince us that the process hasn't been used safely for more than a year at any other factory.

    Why this is right

    The only thing we care about is whether or not this proposed new welding process has been used safely for more than a year at another factory. If it hasn't, then we've proven the conclusion (i.e. justified the application). According to this answer, the new process has never been used at any other factory. If it's never been used elsewhere, then clearly it's never been "used safely for more than 1 year" elsewhere. Thus, we've proven the conclusion! Both parts of the Policy's trigger have been established and so the outcome, "should not approve", follows.

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

  5. Unclear Impact1% picked this

    The proposed new welding process has been used in only one

    The only thing we care about is whether or not this proposed new welding process has been used safely for more than a year at another factory. This answer tells us that the new process has only been used in one other factory. Okay ... don't keep us in suspense ... at that other factory, was it used safely for more than a year? Since this answer doesn't tell us whether it was or wasn't used safely for more than a year, this does nothing for us.
