Hi all! I'm consistently getting 179-180 on BR but in the mid/high 160s on AT. Any advice on closing the gap? I understand speed is likely a big part of this, but I'm curious what has worked for others in closing this gap? Is it doing drills where you gradually give yourself less and less time? I particularly feel that the timing on RC is really tough.
@dedolence Same here. C felt "weaker" and thus more appropriate for a necessary assumption question, but C is actually more broad -- it tells us we would need to assume a "likely decrease," which is much broader than the absence of a "significant increase" that would replace the departure of day-care workers to better-paying jobs in other fields.
@PhoebeHopp For the student response, I do not think AC B is saying that the "increase can't be big enough to account for all the new demand." In fact, as you point out, all AC B gives us is that the number of new day-care workers will not be "significant" -- we know nothing about how this number relates to the number of new parents demanding day-care.
I actually think the more specific language of AC B makes it more necessary to assume than AC C. If we negate the idea that there is not a "significant" replacement for the day-care workers who have left, the argument falls apart much more than it does if we negate the idea that there is a "likely" decrease in the number of day-care workers.
@7SageTutor You acknowledge here that (C) is a sufficient assumption. But the question prompt asks for an assumption on which the argument "depends." Please explain how we should approach such questions that ask for a necessary assumption but the correct answer is sufficient and not strictly necessary.
I'm not convinced that (C) is necessary. In fact, I see it as more of a sufficient assumption. If no one incompetent makes it through the evaluation program, this guarantees that any one who has passed the evaluation program (and is a recognized medical specialist) is competent.
I also think the language in C makes it more like a sufficient, rather than a necessary assumption. It discusses a "particular specialty" and "the evaluation program for that specialty." This is not like the stimulus' conclusion, which discusses "recognized medical specialists." It's not necessary that all types of specialists be competent for all recognized medical specialists to be competent.
When I read C, I interpreted it as the kind of trap answer choice that attempts to reject a premise rather than weaken it as a "bridge" to the conclusion. We are told that there is an inverse correlation between depression and left frontal lobe activity. Doesn't that imply that they are subject to the same type of variation?
