diagramming

Hello @isabella, The problem with your diagram is not that you combined the two conditions. The problem is that you used "&" instead of "or." The correct diagram of the first sentence is this: SC or SH ---> not PS it is also acceptable to separate them. SC ---> not PS SH ---> not PS When we have an "or," it means that just one of these sufficient conditions will bring about the necessary. This is why we can write them separately. However, you cannot cannot do the same with an "and" statement. I understand your confusion, because the first sentence does include the word "and." However, you created a diagram of this sentence: "Any small country that is in the southern hemisphere does not have a permanent seat." This would be represented by: SC and SH ---> not PS it is not appropriate to separate this into two statements, because we can't make a conclusion based on one of these conditions alone.
