I was starting to make a blueprint of my first exam in Set Theory and I came across a question that describes the intersection of three sets and the student is to choose the Venn Diagram that represents that situation. 

This is what is stated in the Standards for Excellence. 

• solve problems that involve three sets

• explain the reasoning used in solving set theory problems that involve three sets

• identify and correct errors in a solution to a problem that involves at most three sets

Would that be considered a level of excellence since it has three sets or is it an acceptable standard?
