A type of diagram used to classify objects that is usually composed of two or more overlapping circles representing different conditions. An item is placed or represented in the _______ in the appropriate position based on the conditions that the item meets. If an object meets one of two conditions, then the object is placed in region A or C but outside region B. If an object meets both conditions, then the object is placed in the intersection (B) of both circles. If an object does not meet either condition, then the object is placed outside of both circles (region D).
