Undermining the manager's argument: All the restaurants with sales increases were located in areas where almost all alternative restaurants had to close, causing sales to jump out of lack of options.

I'm also highly interested!

Wow this question made me mad, but the way JY explained it makes complete sense!

MOST ants leave pheromones to forage

ALL pheromones evaporate above 45*C

45+ is typical in afternoons in the Sahara

My original correct answer: C

C is a little less attractive at first because the first part of the sentence is fairly specific. It boils down to Saharan ants that only forage in the afternoon (when it tends to be 45+ degrees Celsius) generally don’t use pheromones to guide themselves whilst foraging.

We know that this must be the most supported answer because HOW could the opposite be true given the stimulus? Could ants use pheromones to navigate at that heat if ALL pheromones evaporate? No! Even if they tried to leave pheromones, they wouldn’t be able to GUIDE themselves because they’d evaporate! It’s the right answer because it presumes NOTHING about alternative methods to foraging, which is good because the stimulus says NOTHING about what happens when they don’t use pheromones.

My BR incorrect (tempting) answer: E

Tempting because the first part of the sentence is more straightforward. However, it’s attractive because it plays to our presumptions. We may incorrectly assume that when ants can’t use pheromones, they can’t navigate as well since it’s what MOST ants typically use. However, Saharan ants could be the exception. Perhaps they don’t rely on pheromones and have evolved to the heat to use a different method regardless of temperature, making it so that they always forage at the same efficiency. Perhaps they have evolved to use a different method in the heat, and that method is actually more efficient than the pheromone tactic. We know nothing, so we shouldn’t presume anything.

In order for this argument to hold up, the cost of installing during the night MUST be less than the cost of installing during the day. If the financial cost of productivity lost during the day surpasses the “savings” from installing during the night (the difference between daytime and nighttime cost of installation,) then installing during the day no longer saves money. That is why B is the necessary assumption.

Put in another way:

Fees for daytime installation = $200 + “productivity lost” cost

Fees for nighttime installation = $400

If “productivity lost” cost > $400-$200 then argument fails

If “productivity lost” cost = $250 for instance, daytime installation = $450, which is obviously greater than $400

#help

Why is answer choice B not a “sufficient assumption”? I overthought this question and incorrectly changed my answer from B to E during BR, but I still don’t get why B is necessary.

I thought another issue with answer choice E is that we have no idea if Einstein’s theories were equally successful to Newtonian physics. All we know is that so far it’s “enjoyed wide success.”

My shot at making myself understand this question through analogy:

Running is a powerful tool for improving cardiovascular health. In a clinical trial, those who ran once a week and meditated improved their cardiovascular health as much as those who swam once a week and meditated for the same amount of time.

Which is an assumption relied upon by the argument?

A) Meditating played absolutely no role in improving cardiovascular health among participants.

C) Swimming is a powerful tool for improving cardiovascular health.

Answer explanation: C must be correct. If we’re holding meditation constant, there must be some benefit to swimming for the argument to hold. Else, if swimming is not “a powerful tool” in improving cardiovascular health, then how can the argument claim that running is “a powerful tool” just like swimming? That would be like claiming, “Running can be great for your cardiovascular health, because it is just as helpful to cardiovascular health as swimming, an exercise that does nothing for cardiovascular health!”

Answer A is deceptive and tempting. It is wrong because meditating does not have to play zero role in bettering cardiovascular health for running to be a powerful tool. Even if meditating plays zero role and was a useless component of the trial, running can still be “a powerful tool” in improvement of health so long as swimming is ALSO “a powerful tool” in improving cardiovascular health. Thus, the argument does not rely on Answer A’s offered assumption. It does, however, rely on answer C’s assumption that swimming must be a powerful tool in order for running to be a powerful tool too.

I’m not sure how I would differentiate between picking answer A and answer C if the language wasn’t so extreme, i.e. if individual counseling was not entirely unhelpful

I also got the question wrong originally. The way I've explained answer B to myself is that if "meeting H.E.S. is primarily a matter of refraining" then that's not necessarily the same as "performing a notably ethical action." Maybe the business performed one notably ethical action, but it's been doing several other unethical actions (not refraining) thus failing HES and not deserving media coverage.

This Q was definitely tricky, however. The correct AC uses weak wording by saying that meeting HES is "primarily" a matter of refraining.

Thanks for the idea!

I assume it doesn't, but just to double check, does the first-time taker score preview apply for people who took the first 50% digital test last July, but cancelled their score?

My mistake: I went for weak + incorrect answer A because I missed C. I assumed C was telling us that

1) the cruel acts were plausible, because they were similar to other tyrants’ cruel acts

2) if anything, Caligula copied other rulers’ cruelty

My error was that I missed these key details in the stimulus: these were “SPECIFIC outrageous acts,” not just a generally similar act & that these were HISTORIES that came down to us. I also conflated “histories” and “little documentation” (thought the little documentation was what came down to us, i.e. primary source documents)

I bought a watch of a similar nature a little before the July test and ended up getting the digital test. I basically didn’t use it at all during the test, so I would say get used to the running time, but of course what works for one person might not for another! If anything, I wished I had gotten used to the digital timer more and could rapidly analyze my time left based on that, rather than my LSAT watch

Using the digital tester on an iPad Pro within the 7Sage app, I can't highlight or underline anything within the RC section (LR was fine).

I got the answer right, but I had trouble wrapping my head around D. This is my understanding:

-R leaves curl at under 0 degrees

-C blossoms at above 2 degrees

A person sees uncurled leaves (so we’re not under 0 => we’re 0+ degrees by the Rhododendron) + lack of blossoming (so we’re under 2 degrees)

The stimulus says that this gives us reason to believe the 1 degree thermometer reading is accurate by plus or minus 1, as the “real” temperature must be between 0 and 2.

D is correct because it points out an assumption (that the real air temperature should be approximately the same by both plants), when in reality the air temperature will differ by each plant by over 2 degrees. This means that, by the Rhododendron, it could hypothetically be 100 degrees & by the Crocus, it could be -40 degrees. Therefore, the thermometer may not be accurate by plus or minus one.
