I always have the most difficulty with these questions because I'm never sure how to begin approaching them.

There is, however, a simple way to look at them, and that is to paraphrase them this way: which answer choice would you diagram exactly the same way as the rule you are getting rid of? The same representation, the same inferences, nothing left out and nothing new. Focus on how you would diagram the answer, and that often makes at least a few of the answers immediate losers.Thanks Adam. I'm excited to try this out. Is there an index where I can find the specific question type among past logic game question sets to practice with?
For example, take a look at question 7 in the September 2017 games section. We need a rule that will be diagrammed the same was as "S must be in the West Theater." We likely would have diagrammed that with a "not law" to the right of the row for the East Theater. Which of the answers would make us do the same?
Answer A is about sequencing. We would diagram it with a sequencing notation, not a not-law. That's out.
Answer B creates a not-block, not a not-law. That's out.
(so far I haven't actually diagrammed anything, I've just though about how I might diagram these answers and whether it might be the same as what I did with the original rule being replaced)
Answer C: This is a little different than the previous answer, because I know where U is - it's in the East Theater. So S cannot be in the East Theater. That was my prephrase! Contender.
Answer D: I would diagram this rule with a not-block, not a not-law. Loser.
Answer E: Another sequencing rule, which is not what I am replacing. Loser.
C must be correct, and no diagram needed! Just think about HOW to diagram the new answer, and pick the one that would be diagrammed the same way as what you are replacing. A much simpler way to conceptualize these questions, isn't it?
Give that a try and let us know if that helps you get your head around these otherwise challenging questions. Good luck!
