56 Game 3

Heck yes.
So is the first rule the reason that there can't be multiple types of trees in each park? That part went over my head and the number of possibilities paralyzed me :(
I'm not understanding your question: there are certainly multiple types of trees in each park. Rules Two and Three, for example, demand that two different types be planted together.
So this is the first binary grouping game I've seen where the notation for the right-hand column is not negated terms (the usual format being: G on the left and not-G on the right). This is helpful since, if we used the typical format, we might run into trouble applying rule 3 (mistakenly thinking that within group not-G, if we had not-T then we would have not-O).
So two questions: 1) Am I right in thinking that the usual right-hand negative notation format would get us into trouble? And more importantly, 2) in the interest of making games as mechanical as possible, what features of this game tipped you off that it would be more strategic to leave the right-hand column un-negated?
I think my reasoning was that here, you could have, for example, S on both the right and the left at the same time. So in this game, Not-S doesn't really mean not-S.
Think of that as opposed to the majority (perhaps every other?) of BG games, in which Not-S actually means that S is not on the left (because it's on the right).
That's what was going through my head.
Hope that helps!
Ah, totally! In other words, you spotted that group membership isn't mutually exclusive here.
Very helpful, thanks!
I see what bcarmack was saying—I made this one WAY more difficult than it needed to be because I didn't realize that "Each of the parks is planted with exactly three of the varieties" meant "Hey, there's only three on each side." I thought it meant you have to have AT LEAST three of the four, but you could have, I guess, an infinite number on either side.
What made it clear we were only dealing with three spaces on each side? Rule 1?
Well, it was precisely the language you've quoted from Rule 1. If we must have exactly three of the varieties, then we cannot have four varieties (that's not exactly three). The test writers are very precise with their language (like all good lawyers are!) and they intend for us to take the plain, denotative meaning of the words they use. So just take everything you're told at full face value, and you'll be fine.
Dave I don't understand question 14-(A). you drew (1) G: T/ S/ M L: S/ O /T and (2) G: T/ S/ M L: S/ M/ T. I did same thing concerning (1) but I don't know why the answer choice (a) also means (2). I thought the number of the parks planted with maples is 2 and the number of the parks planted with oaks is 0, so it's not equal.
