Before revision:  First, we formalize this form of disconnected reasoning and propose contrastive support sufficiency as a better test of multifact reasoning.
After revision:  First, we formalize such undesirable behavior as disconnected reasoning across subsets of supporting facts. This allows developing a model-agnostic probe for measuring how much any model can cheat via disconnected reasoning. Second, using a notion of contrastive support sufficiency as a better test of multifact reasoning.
