Are there any important inferences I needed to make? I tried to look over the possibilities based on whether U was in the same spoonful as Y or Z.
General Rules
T < U ≤ X
W < Y

Possibilities (Given that Z is Random)
WT < UY < X
T < W < UYX

WT < UZ < YX
W< TY < UZX

Z isn't really random here, LSAT20148, because it is in the rule about U having to be paired with something. Other than that, I think you're looking pretty good here! You've identified the numerical distributions of 2-2-2 or 3-2-1 (unfixed).

I think you will find that there are many more possibilities to this game, and I wouldn't chase them all down, especially since there are only 5 questions. Don't box yourself in by thinking that these are all there are, but instead use them as a jumping off point to help you understand the game overall a little better. I didn't see any major inferences in this game, and I only chose to do a single hypothetical before heading to the questions. I based it on the 2-2-2 distribution since I saw that it really boxed U in tightly:

T would have to be in the first spoonful, U in the second, X in the third. either Y or Z would go with U. W would have to go with T since it couldn't be in the last spoonful, and then the leftover of Y and Z would go with X in the last spoonful. So it looks like this:

TW - U Y/Z - X Z/Y

Two solutions, one template, and that covers the 2-2-2. For the 3-2-1 I could see that there were too many choices for which group was what size, so I just moved to the questions figuring I'll work those out when and if I need to. That happened, for example, on question 19, where I worked out a 2-1-3 and a 2-3-1 to see what could happen when Y was alone.

For this question, I started with figuring out which letters cannot go in the first or third spoonful. U,X, Y cannot go in first and W/T cannot go in third. this was my jumping off point. Did I miss any key inferences? I didn't want to spend too much time writing out scenarios and went straight to the questions after this.

menken,

I sketched a diagram out quickly myself on some paper and didn't really see any other inferences. Everything beyond what you said is very conditional, like "If U is not with Z, then W is before U," which is true, but why bother thinking of such a specific case? Most of the questions are local, which seems to bolster the case that minidiagrams for specific questions are going to be the way forward in this game, not an inference-heavy main diagram. The only other choice is a bunch of templates, but Adam showed earlier in this thread why templates are probably too numerous to be useful here.

Hi there,

This game is from PrepTest 50 from Sept 2006. It's now April 2021. Could Powerscore post an explanation and breakdown for this LG and its questions? Or if you already have, could you direct me to where I can find it? I can't find it in the course or the bibles. Please and thanks!

Hi 2020,

Thanks for the post! I have let an instructor know to explain this one for you!

We are working on transferring over our full explanations for all LSAT questions. But, as there are thousands of questions, this process will take some time yet. In the meantime, please let us know if there are any you have specific questions about and we are always happy to help!

Thanks!

Hi 2020,

Below is a basic write-up of the structure, rules, and inferences in the game, as well as a basic diagram of the same. Hopefully this helps!

1. The scenario makes clear that at least part of the task in the game is a grouping task. We must assign each of 6 letters to exactly one of 3 spoonfuls. This creates a Defined grouping scenario, in which we know that the total number of grouped variables (across the 3 spoonfuls) will equal 6.

2. The scenario does not fully define how many variables will appear in each spoonful, instead giving us a minimum (1) and maximum (3) for each spoonful. This creates a Distribution uncertainty in the game, and it is to our benefit to determine the distributional possibilities in advance. With 6 variables, and a minimum of 1 in each spoonful, there are two distributional possibilities: 2-2-2, and 3-2-1. The distribution is unfixed, because in the 3-2-1 distribution, we do not have sufficient information to determine which spoonful gets 3, which gets 2, and which gets 1 of the letters.

3. The rules clarify that there is also a sequencing component to the game, using language about which letters are "later" than other letters. These rules require us to use sequencing diagrams, and to pay attention to Not Laws.

4. The first rule places U in a later spoonful than T. This allows us to infer that T is not in the 3rd spoonful, and U is not in the 1st spoonful (see the Not Laws in the diagram).

5. The second rule is phrased negatively. Since U is not in a later spoonful than X, U is either before X, or U is in the same spoonful as X. This is represented diagrammatically using the "Double Dash" diagram. Since X will not be able to come before U in the diagram, this means we can add a Not Law for X underneath the 1st spoonful.

6. The third rules places Y in a later spoonful than W. This allows us to infer that W is not in the 3rd spoonful, and Y is not in the first spoonful. There are now only three possibilities for the 1st spoonful: T, W, and Z.

7. The fourth rule places U in the same spoonful as either Y or Z, but not both. Block diagramming represents this rule. Since it is uncertain which of Y or Z is with U, there are no additional Not Law inferences we can draw for Y or Z. The "not both" component of this rule is difficult to represent diagrammatically, so it would be advisable to highlight or underline this part of the rule so that it is not forgotten.

8. The diagram below depicts the rules, inferences, and a Template for the 2-2-2 distribution. The 3-2-1 distribution is far too open-ended to permit an efficient use of templates, so it is not advisable to pursue templates using that distribution.

Thank you @Stephanie and @Jeremy! Look forward to those explanations that Stephanie mentioned! I like the Powerscore method and have invested time and money into the Powerscore Bibles and the LSAT Course, but the one shortcoming is not having full explanations for each of the questions and answer choices. For example, I would love to have full Powerscore video-guided explanations (like 7Sage for an example of what I mean), where you go through each of the questions and answer choices using the Powerscore method and concepts. But even if it's not in video format, written format with diagrams would be awesome too -- similar to the full explanations in some of the homework practice sets!
