JY mentioned that a good way to approach RRE Questions would be to view them as weakening questions by negating the last premise / including a new conclusion and then finding the AC that most weakens the new argument.
While this works for regular RRE questions, i'm struggling to apply the method to EXCEPT questions and questions in which there isn't a paradox.
Any advice would be extremely appreciated as this is the question type I struggle with the most.
the way i understood this (no hard math like other explanations), hope it helps!
first off, always remember that percentage increase decrease does not necessarily impact total amount of money spent/present. JY's mapping out shows that there are three different directions that the total amount spent on the disease can go: either total spent increases, stays constant, or decreases.
Now, the stimulus tells us that in every single possible option, there IS a decrease in percent spent on standard treatments. The conclusion tells us that LESS money is spent on standard treatments. How can this conclusion be possible? Only if the amount of total money stays constant or decreases.
D is wrong because all it tells us is Total$ ‑m→ /Standard treatment (most of the total money was spent on nonstandard treatments). Why is this wrong? Because in every single condition of the total either getting larger, staying constant, or getting smaller, we already know this to be true because of the stimulus (just look at the mapped out version-- in every single circle, more is spent on nonstandard). So basically this does nothing but reaffirm a premise.
C indicates the opposite, more spent and not less
B we don't know this and there is frankly no way to know this
A "varieties" not discussed, quick cross out
