Re: Makes sense...
How do we know to look for the "number that's a multiple of 8, minus 1. Like, 7, 15, 23, etc..." Still not clear why we know to look for this portion of the solution. J I guess it just comes with experience with number properties. However, if you notice, the applicability of the 48 even n...

Having taken the LSAT and studied for it (I'm in law school right now), I can tell you that even though you get 2 minutes per question on GMAT as opposed to a little over a minute per question on the LSAT, the GMAT critical reasoning is substantially easier than the LSAT's equivalent (the upper eche...

OP, what's up with the answer choices? The link confirms Neo's method.
Neo - the term 6! * 7! is also equal to 10!. Any relationship or just coincidence?

Crap! i read the Q as 7men and 6 women So 7men can be arranged around a table in 6! ways and there are 7 places for 7women to sit between the men = 7! ways Your final answer has to be 6! x 7! This seems highly inaccurate given that the largest answer choice is 24. 6! x 7! = 720 * 5040 = a seven dig...

Agree with A - it doesn't strengthen or weaken. It's just extraneous information. D is incorrect - it strengthens the argument because it eliminates an alternate reason for declining amphibian populations. If their habitat was shrinking because of deforestation or pollution, then that could be a rea...

48 comes from the fact that every single even number works in this equation, and here's why. Take n=2. It'll end up being 2 * (3) * (4)... now if you factor this out, you'll see that you get 2^1 * 3 * 2^2 .... This leads to 2^3 = 8*3. Take n=4.... 4*5*6.... same thing as 2^2 * 5 * (2*3)...another 2^...

would go for C. the stimulus advocates teaching history by spending most class time recounting the lives of historical figures and very little on dates and statistics. it doesnt say the teaching has to be able to spend most class time recounting lives of historical figures without referring to the ...

I got D. E is irrelevant - packaging has nothing to do with anything - this answer relates price to package, not price or package to effectiveness. You need an element of effectiveness to weaken the conclusion - which is that SineEase is the most effective for the price. C - consulting a doctor does...

IMHO - C B states that "the previous estimate of the mass of Haley's comet was very low".. But this is not true as the main statement states that according to recent findings "haley's comet refelects lesser light than previously estimated". Previously they had estimated more lig...

I think C is incorrect also. I would have to go with B. Just because a hospital is able to buy it cheaper does not mean it's less effective. If it said something like, "Novex sells to hospitals at a price discount that undercuts the competitor's prices" then I would buy into C. But because...

I Pick A also. Here's the error in the stimulus that Odysseus points out: Priests say "acknowledge the power of the gods" based on premise X. Odysseus points out that this is anecdotal evidence that leaves out the alternative (Praying and Dying as opposed to Praying and Living). Answer A s...

IMO the person who posted answer C is incorrect. I think the answer should be B. The premise of the argument is that scientists estimate mass of comets based on its brightness / reflection. Given that, scientists know how bright a comet is because that's the independent variable. Mass is the depende...

The square root symbol is defined as a function: it only produces one answer. By definition, the square root symbol gives the *non-negative* square root of whatever's underneath the root. So if you see the square root symbol over the number 9, the answer is most certainly 3, and most certainly *not...
