Thanks for the question, Marce, and it's very timely, as I was just having this discussion last night with my class and again this afternoon with one of my tutoring students.
First, when you are supposed to suspend or replace one of the global rules for a local question, they will tell you explicitly that they are doing so. If they don't make it clear from the question that you are to disregard or alter one of the original rules, then they all still apply. Typically, when they do this, it will only be on the last question of the game, and they will also explicitly tell you that all the remaining rules still apply. For example, look at Question 5 of Game 1 in Lesson 3, on page 3-20 and 3-21 of your course book. That question tells you to change one of the original rules (about G and H not being next to each other) but to leave all the other rules in place. That's the way they should work.
You'll see plenty more examples as you work through the course. Be patient, and your instructor will help you work through them. Remember, on all games you should assume nothing, but rely solely on what they tell you. If they don't tell you that a rule is suspended, it isn't!
The best way to attack local questions (those that start with "if" or "suppose", creating a temporary new restriction for that question only) is usually to draw a new, simplified version of your main diagram that incorporates the new restriction. We sometimes call that a "mini diagram". It should be a rough sketch of your main diagram, just to capture the new restriction and any inferences you can make based on the original rules and their interaction with the local rule. For example, if your game has a global rule that P is always immediately before W, and you get a local question that says "if P is 3rd, which of the following must be true", you would draw out the slots for your base, place P in the 3rd slot, and then place W in the 4th slot. Then see what else must be true based on other rules.
Be patient, all will be explained in time! Be sure to ask questions during your class. I know as an instructor that a class full of questions is much better, much more interesting and engaging and helpful, than a room full of quiet people!
Enjoy the course, and keep at it!
