A. That isn't accurate, my questions read more like, e.g., "if Anna flies in plane 4 and Dave flies in plane 2, which of the following..." B. Even if that were the case, putting the word "is" in all-caps doesn't change the fact that it is absolutely possible and not in any way a stretch to say Anna IS on plane 4 and she IS on plane 3 during the airshow.
Just as you might say "B IS in the Customer Relations course and IS in the Marketing course during the business seminar." Or more similarly to our game "B TAKES the Customer Relations course and the Marketing course during the business seminar."
You seem to have a need to finish your posts with some meaningless "commonsense."
Neither "putting game pieces in their respective slots" or "what blocks fit in what holes" have any relevance to the game we're discussing or to most LSAT games for that matter. Games where the variables can fill more than one position in the same game aren't rare or "complex hypotheticals" nor do they require the "Blue Angels to show up" they are actually a pretty basic game type. You seem to be prepared only to deal with the most basic of game types which call for placing an even amount of variables in an even amount of positions 1 variable per position. The actual LSAT has far more complex games and if it's too much for you than maybe the LSAT isn't for you, but in any case you definitely shouldn't be offering advice on how to prepare.
