This drill is tough because it's asking us to really guess a lot in terms of what type of game we're even doing.
We can tell in Q28 that it's ordering.
And we can tell that while "ballad" is limited to one, because the language of "his ballad" is singular,
"rock songs" are not limited to one, because the language of "any of his rock songs" is plural.
So we could have written the rule as
B - all R's
that's saying "the ballad is before all rock songs"
They wrote a B = 1 to indicate that there will be only one B.
There's no great reason why they're writing "domino tile" rules characteristic of a 3D ordering game. The way they're writing the rule implies that this game wants us to keep track of a couple things:
for each song, who is the player (Marcus or someone else) and what type of song is it (ballad, rock, other)
But you wouldn't be able to glean that sort of thing from just the rule. It could be a game in which all the songs are from Marcus and we only need to keep track of what genre each song is.
So don't worry much about not being able to match what we wrote --- that was quite a stretch.
