cwolfington Wrote:I also picked (D) at first. It's wrong because it creates a double-arrow where one doesn't exist, i.e: Primary goal <-->Ever-expanding regulations.
But the author's argument is: Primary goal+Appeal procedure->Ever-expanding regulations; so (D) ignores "appeal procedure", and it makes a double-arrow, which can be negated without weakening the argument.
You're on the right track,
cwolfington, but you should be careful about a few things in your dismissal of
(D). Let me break down the argument core:
PREMISE: IB goal = define/classify all problems, set regs for every situation
IB has appeal procedure for complaints
IF complaint raises unanticipated problem --> regs are expanded
CONCLUSION: IB will have "ever-expanding" regs
Interestingly, we don't actually need the first premise here. The goal of the ideal bureaucracy is more or less irrelevant to the argument. Things we NEED are: 1) there to be some complaints and 2) those complaints to raise unanticipated problems. And we need that to happen into infinity (to support "ever-expanding").
What we DON'T need is anything at all about the "primary goal", so the fact that
(D) invokes it is a huge red flag!
I must stress here, though, that the answer did not NEED to saying anything about the appeal procedure. Remember, we're looking for an assumption that NEEDS to be true - we're not looking for a sufficient assumption that would guarantee the argument.
You are absolutely correct, though, that the biconditional arrow is pretty darn suspect. Why in the world would we
need a biconditional arrow to support the conclusion? Assumption answers are often in a conditional format -
If [premise] --> then [conclusion], but it's a rare thing indeed for a Necessary Assumption to be a biconditional.
As an added bonus, the clause about the "primary goal"
(D) talks about whether the ideal bureaucracy "can reach" that primary goal. The stimulus only mentions what the primary goal
is.
