Diagram and solution to problem # 4 attached.

[dan]

Attached is a full solution (setup and questions) that our San Francisco instructor, Kim, wrote up. It's a different approach that uses frames.

How long should it take to diagram this Q with frames? I missed the L--K inference when I did this during my timed PT. I was able to answer all questions during review but framing took some time.

Thanks!

On the work out diagram solutions in the student portal it says that in this game J and L are interchangeable and hence can't be linked. Does this mean in general that when we have rules where we don't know the precise ordering of two variables (if it's after or before) we should not attempt to make like a "relative ordering diagram "of trying to combine the rules together ? In other words, we should not be combining rules until we get to the question?

Yeah, that's a fair generalization (that may have some narrow exceptions here and there).

If you have reversible chunks, it's usually dangerous to
- link other rules to them
- try to base frames around them

That said, this game is one in which I might make an exception, since G, L, and J all show up in 2 rules.

I approached questions 5 and 6 using trial-and-error and found that to be quite time consuming, but it seemed as though the frames might take some time to set up as well, and so how should we decide when to frame in a case like this, when it's not just one either/or?

[ohthatpatrick]

There's not a correct answer, so just go for one of them and then live to regret it / be grateful for it later.

I am very frame-loving. I will routinely frame a chunk with four options. But I would counsel AGAINST framing on this game (and I only know that because I tried to frame it).

Part of being good at framing is understanding that most frames don't pan out and trigger anything. So I quickly survey for the ones where stuff starts clicking, and any of them that don't have an initial triggered response I quickly leave as is.

This game's frames become a bit of a quicksand pit, since you can ALMOST figure stuff out, but you would need to sub-frame some of these reversible chunks in order for something to be triggered.

The lesson I learned from this game (and another similar ordering game with two reversible chunks) is that framing with reversible chunks can be dicey. If it starts feeling too iffy, just get moving onto the questions.

Or ... fully commit and do the 8 frames you'd need:
J _ L in each of its four options
and
L _ J in each of its four options

Many of those would flesh out. At least one would blow up. But 8 frames is pretty crazy for 99% of test takers.
