Sets, supersets, members practice problems?

Does anyone know if there's a filter to look for sets vs. supersets type questions? Or is there a place in the core curriculum that deals with these issues? I'm not talking about just the valid vs. invalid inferences from existential relationships, but more like the more recent PT questions that have stimuli like "most mammal species of ... are not, but most individual mammals are ..."

Does anyone have any advice on how to systematically (with a process) attack these problems? I usually do them based on my intuition, but I find that can just be very nerve-wracking. Sometimes, I draw circles/Venn diagrams, too, but I never quite know what to do with them/it's hard for me to infer anything from them.
