Hello friends,
Just curious when doing practice Preptests, you can filter to Legacy which includes 4 sections or "Current" which only includes 3 sections. I plan on taking the June 2024 LSAT. As far as I understand, there is still an experimental section on the actual LSAT so for practicing purposes are you guys doing the "Legacy" method of all 4 sections? For those doing PT's with the "Current" of 3 sections, what reasons do y'all have?
I initially thought the same way as you but through eliminating the other answer choices I was still left with AC B, except I reached it through a faulty way.
I initially thought, like you, that maybe the bats could simply smell one another or remember where in the cave they left their pup and because the argument only relies on "communication" as a means of the mother bat finding her pup, then that meant the author "excluded alternative explanations" (smell, location, etc.) which in turn made his reason of mom pups being able to distinguish valid.
However, the author did in fact consider alternative explanations and did tell us they are not possible. The argument clearly states "the bats calls are the only means of finding one another" so the author has already taken the possibility of smell, location, and all other explanations and stated that it was not possible (which we have to take as being true). This means either the pup can distinguish the calls of the mom, the mom can distinguish the calls of the pup, or both being able to distinguish separately. But again, the author eliminates the possibility of the pup being able to distinguish the calls of the mom (which by extension, eliminates the possibility of "both" being able to distinguish).
With all these considerations, that only leaves the possibility that the mom must be able to distinguish her pups call from others and hence AC B states" establish the validity of one explanation [that the mother bat can distinguish her pups call] by excluding alternative explanations [smell, location, etc. etc]" which is exactly what the author did through the reasoning stated above.
I managed to get this question right simply due to process of elimination but the logic part I am struggling with. The statement reads "unless they are NOT intended for the general audience" they "ought to include discussions of both the utility and aesthetic appeal of each of the buildings they consider".
I translated that as /U & /AA -> /GA and the contrapositive being GA -> U or AA. The statement "ought to include discussions...." I negated and made into the Sufficient (/U & /AA) and the statement "unless they are NOT intended for....." already has a negation in it and hence why I translated it into /GA. but according to JY (who took the contrapositive) it should have been GA - > /U or /AA.
Can someone please explain where I went wrong?
