#feedback I think it is really important that 7sage in the future is clear about which practice tests are used throughout the core curriculum for its "you try" and explanation questions. Some of them are from more recent tests which is annoying if you want to use those tests for clean PTs. For example, why use PrepTest 143 - Section 4 - Question 03 for lesson 2 of Most Strongly Supported Questions in the curriculum. Why not use a question from an older test. That is a pretty recent test and should be reserved for PTs. This means there are fewer PTs for students to use to gauge their true ability. If you need to use more recent questions then it should be clear which tests are being used and isolate the curriculum problems to just those few tests so that we don't waste valuable tests.

This is how I understood it. I'm pretty sure this is right but if I could end up confusing you more so sorry.

Think of it using Garfield and fat cats.

Where Garfield there will be a fat cat. Garfield → fat cat.

Then the counter positive: where there is not a fat cat, there is no Garfield. /FatCat→/Garfield

Independent judges are the subset and the good legal system is the superset. If you see an independent judge, then you know you are in a good legal system. But you can have a good legal system without independent judges, just as you can have fat cats that are not Garfield. While our intuition may say that independent judges is the superset for a good legal system, that is not what the phrase says. Here if you have independent judges, then you must already have met all the other prerequisites to have a good legal system. Independent judges is sufficient to have a good legal system and a good legal system is necessary for independent judges.
