Vocabulary scoring

The question was raised in class about the additive properties of one-point answers: Do two one-point answers equal two points?
The answer is: sometimes.
As per the class discussion, if the examinee says a bed is "something you relax on" as well as "furniture" (both 1 point answers), together they make a 2-point answer because of their additive properties.
However, if two 1-point answers are given that do not improve upon one another, only one point is given. For example, "Apple" : "Food" and "healthy" - although those are two correct one-point answers, they don't improve upon each other and therefore the score is one point.
