#8 - Local, Must Be True

[Dave Killoran]

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?f=170&p=88166#p88166)

The correct answer choice is (D).

When R and S receive the same rating, they form a block that takes up one of the “2s” in the 2-2-1-1 Numerical Distribution. Because R is now paired with S, from the third rule we can infer that H and I must form a block, thus occupying the other “2” in the 2-2-1-1 Numerical Distribution. Therefore, the other two CDs—N and Q—must each be the only CD to receive their respective ratings. By applying the second rule, we have three block formations that encompass all six CDs, and that cannot overlap:

As previously determined, Q must receive either three or four stars. If Q were to receive three stars in this scenario, then only the RS block would be available to receive four stars, but this would cause a violation of the final rule. Thus, Q must receive four stars. Accordingly, answer choice (D) is correct.

With the other two blocks, there are two placement options:


RS receives one star:

RS receives three stars:

I'm lost on how to find out what must be true in this scenario. If it becomes RS then I can Infer HI and N must go before HI. Although, after that I am a bit lost. Its seems as if this RS, N, and HI, can move around within the first three ratings.

Hi KG!

Below is a rough diagram of the game pieces for this question, which represents the inferences you accurately identified in your post (so you were off to a perfect start!). The only rule these inferences (and this depiction) don't account for is the last rule about Q. We already know from the Global diagram to this game that Q gets either 3 or 4 stars. In this particular question, Q can't receive 3 stars. If it did, then RS would receive four stars (breaking the rule that at most one CD received more stars than Q did). So Q must receive 4 stars, our correct answer (answer choice D)!

I hope this helps!
