Final answer:
An unlicensed assistant in Nevada can distribute promotional materials and schedule property showings but cannot draft real estate contracts as this requires a licensed professional and entails legal knowledge.
Step-by-step explanation:
An unlicensed assistant in the real estate industry in Nevada has limitations on the activities they can legally perform. While such assistants can engage in certain support tasks, they must avoid activities that require a real estate license. Drafting real estate contracts, negotiating commission rates, and other activities that involve the interpretation of law or represent the interests of a client in a transaction are prohibited. Among the options provided, an unlicensed assistant may distribute promotional materials and schedule property showings as these activities do not require a license. The one activity they may NOT perform is drafting real estate contracts. This is because drafting contracts involves legal knowledge and acting in a capacity that requires a licensed professional.
