Misunderstanding

Hi, for a parallel reasoning question we need to find an argument that has the same structure. Let's look at the structure of the initial argument. Some Fj sell to LMs If SR then Not sell to LMs SO some SRs are not FJs I would maybe take this a step further and say Some Xs do Y If Z then Not Y So some Zs are not X. C matches this pattern. Some S prefer H If C then not prefer H So some C are not S
