Diagramming "at least" statements Forum

[TunnelVision]

On PT30 Game 1, there are rules like "There are at least two kinds of loaves." And "If two or more of the loaves are unsliced, then at least one of the unsliced loaves is rye."

What is the best way to diagram statements like that? I found the questions to be rather easy, but the setup for this game took me too long and I ended up confusing some rules probably because my notations became too complicated.
