Final answer:
Yasmin likely determined the meaning of "monocracy" as being related to "ruling" by connecting it to the similar word "monarchy."
Step-by-step explanation:
Yasmin likely determined the meaning of "monocracy" as being related to "ruling" by connecting it to the similar word "monarchy." A monarchy is a form of government where a single person (a monarch) holds political power. Since both words start with "mono-" and relate to governance, it is reasonable to infer that "monocracy" also involves ruling by a single person.
