Answer:
The comparative form (La forma comparativa)
Explanation:
The first sentence "yo tengo más dinero que Rafael" is a comparative form because speaker A is saying that he/she has more money than Rafael. So Rafael has less money than speaker A. The second sentence "yo tengo menos dinero que Rafael" is also a comparative form because speaker A is saying that he/she has less money than Rafael.
