Diagram

[ManhattanPrepLSAT2]

Hi everyone,

Attached you will find a diagram and potential frames for Game 3. I've also posted diagrams and frames for Games 1, 2, and 4 in other parts of the forum.

These diagrams were originally created for the Review the December 2010 LSAT Workshop. If you are a student of Manhattan LSAT, you can access a recording of that workshop.

Much of the workshop focused on the use of framing techniques to diagram games. We've attached a traditional diagram, and a potential set of frames, for each of the games from the December exam.

Keep in mind that framing, and diagramming in general, is a highly subjective exercise. No two Manhattan LSAT instructors will diagram and solve a set of four games in the same way.

We hope these diagrams will help you gain a better understanding of what frames are, and how and when they can be useful. We'd love to hear from you if you see any additional inferences, or if you've got a different diagram or set of frames that you think work equally well--or better! Also, of course, post here if you have any questions about how to solve any of the problems using these diagrams.

Hi Mike. Thanks for the diagram. Two questions though.

1)On the third frame, is S not restricted to F and T restricted to H? Can there really be a dual option? The other T must come after the QT piece on G. There cannot be another QT piece of F due to rule #1.

So under what scenario can T go on F and S on H, with all other conditions true for the third frame?

2) Also, isn't there another frame like the following:

Code: Select All Code

S           Q   T
R   Q   S   T   R

I may be missing it, but I don't see this scenario covered under the three frames. But maybe it violates some rule that I missed (which wouldn't be a surprise; made a lot of stupid mistakes in this LG section overall).

edit: Oh, nevermind on my question 2 - I see it is captured in frame 2.

You are right w/#1 -- nice inference -- thanks! -- the post has been updated with a new diagram.

I would add another inference to the diagram: that one empty slot must be on H, because Q and R can't be there, and S and T cannot go together.

That's a terrific inference - thank you for your insight!

Is this a close grouping game?

I'm confused why the second R has to go to the I conference in the first frame?

[ohthatpatrick]

The placement of the two R's was the whole starting point for all the frames. That's why they're shown in blue.

We are saying the 2 R's will be either
F, I
F, L
or
I, L

So you're looking at the 1st frame, where we start by assigning the 2 R's to F and I, in order to see what, if anything, might get triggered.

Putting the 2nd R in column I was an arbitrary move, from which we wrote in all the necessary implications.


That's basically the spirit behind framing: arbitrarily create 2 or 3 worlds that collectively represent all the the options for a given idea within a game (we created 3 worlds that collectively represent all the options for the 2 R's in this game).

Then see if you can deduce anything from those starting points.
