Elias's response indicates that he has difficulty with hierarchical classification, which is the ability to understand that objects can be classified in multiple ways, and that one category can include another. In this case, cars are the superordinate category and red and blue cars are the subordinate categories. Elias erroneously thinks that red cars are a separate category, rather than a subset of the larger category of cars. This suggests a lack of understanding of hierarchical relationships.
