Syllogisms and seating arrangements: how do you avoid the answer that is designed to look right?
Solve syllogisms by drawing the weakest diagram the statements allow and accepting a conclusion only if it holds in every diagram, remembering that "some" means at least one. Solve a seating arrangement by placing fixed clues first, branching on the rest and eliminating, never stopping at the first layout that fits.
Answer
Short answer
Decoy options win because they sound true. In syllogisms, a conclusion counts only if it is forced: draw the loosest diagram the statements permit and check whether the conclusion survives. In a seating arrangement, place the clues that fix an absolute position first, branch on the rest, and eliminate branches until one layout remains.
