A national art exhibition features six different types of artwork: Abstract, Baroque, Cubist, Digital, Expressionist, and Folk. These artworks are divided among three galleries: Gallery A, Gallery B, and Gallery C. Each artwork type is displayed in exactly one gallery, and no gallery is empty.
The correct answer choices are Gallery A = Expressionist Only and Gallery C = Cubist & Folk
To figure out these answers, I listed out three galleries and started assigning the artwork type as I found out more information from the base question or the rules. I also defined that if Gallery B has 3 types, the other two Galleries add up to 3, and we just need to determine if each has 1 or 2. If those sources of information were not enough, I then looked at the answer choices and used each option to determine if that combination was feasible and each artwork type was used in a way that still fulfills the rules.
Gallery A - 1 or 2 types
Gallery B - if this needs Gallery needs 3 artwork types, 3 are leftover between Gallery A and C
Gallery C - 1 or 2 types
Types Breakdown
Folk - this is definitely in Gallery C so let's see which possible answers give us this
Cubist, Folk, and Digital only (this doesn't work because Gallery A + C need 3 types, only one cannot have all 3)
Cubist and Folk only (Possible Answer)
Cubist only (doesn't include Folk, which is a rule)
Baroque and Abstract only (doesn't include Folk, which is a rule)
Expressionist Only (doesn't include Folk, which is a rule)
Folk Only (Possible Answer)
Now that we know Gallery C has one of two answers only, we can determine Gallery A
Cubist and Folk only (Possible Answer - if correct, then Expressionist must be in A or B according to rule 3)
Folk Only (Possible Answer)
Digital Type - when we try to assign this, we see that it is not part of a reasonable answer for Gallery C (i.e. it is not combined with Folk, and it is also not an option as a single or pair for Gallery A, which cannot have 3 types). Therefore we know D is definitely found in Gallery B.
Baroque & Abstract - we know these go together as a pair. Since Gallery C already has Folk and needs 1 or 0 more, we know it cannot be in that Gallery. We also know Expressionist can only be in A or B, so if it is in B along with D, we don't have enough space for the pair and the 3rd in Gallery B cannot be Cubist since Expressionist and Cubist cannot be together. We also know Digital is in Gallery B, so placing the pair in the same gallery B could work out well for the figuring out Gallery A.
Expressionist - we know it needs to go in A or B but B is now full - so Expressionist has to go in gallery A. There is no option for it to go in Gallery C. Which means Cubist, which cannot be in the same Gallery, will be in Gallery C. That helps us determine that Folk + Cubist go in Gallery C and now both of our answer parts are clear.
