There will be no question that asks you to identify a MC in an argument where this is none, or else it wouldn't be an argument. There will always be one idea/proposition/sentance being supported but not supporting. The correct AC usually just restates that MC in different but accurate wording. What your talking about sounds like MSS, hope that helps/makes sense

I don't understand how a subject can contain a verb ? #help (Added by admin)
