#6 - Global, Could Be True

[Dave Killoran]

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=5761)

The correct answer choice is (D)

Since it has already been established that H, L, and P must each learn Yoruba, answer choices (A), (C), and (E) can be eliminated. Since we have established that G must at a minimum learn either Swahili or Tigrinya, and it is therefore known that neither L or P can learn both Swahili and Tigrinya, answer choice (B) (as well as answer choices (A) and (E)) can be eliminated. Thus, answer choice (D) is proven correct by process of elimination.

Thanks for your help so much. Just another question.

on page 246 #6. if G---->H am I correct that does not mean that H---->G so therefor H could learn R without G?

[Nikki Siclunov]

This is correct: you cannot make an inference by reversing a conditional statement without also negating both conditions. This is flawed logic (known as the Mistaken Reversal). So yes, indeed, H can learn Rundi without G: just like H can (in fact, must) learn Yoruba without G.

I'm having trouble ruling out E.

Why isn't this a valid->



R:P
S:PL
T:GH
Y:PLH

Everyone learns at least one language, no one learns more than 3 and GH still in the game?

Hi Diggity - the setup you listed would be valid! However, that's not the setup that answer choice (E) gives us. In your setup, the paleontologist learns 3 languages: R, S, and Y. But answer choice (E) tells us that the paleontologist learns 3 languages: R, S, and T. It's not possible for the paleontologist to learn both S and T, because that means that the geologist then can't learn either S or T (due to our Rule about the paleontologist).

Remember in the Setup of this Game we figured out that the geologist can't learn R since we know from our Rules that if the geologist learns R then the historian would have to learn R as well - so 2 people would learn R which violates our Rule about only one person learning R. Similarly, we figured out in the Setup that the geologist can't learn Y because three people need to learn Y, and the geologist learning Y would prevent both the paleontologist and the linguist from learning Y because of our Rule - which would only leave us with maximum two people to learn Y. So to sum up: we already know from our Setup to this Game that the geologist can never learn R or Y.

So if the paleontologist learns both S and T, then there's no languages left for the geologist to learn! This violates the portion of the setup that tells us each researcher must learn at least one language. So (E) is not possible.

Hope that helps!
