Answer
Brief Explanations:
Economics studies how people make decisions regarding resources. The opening of a new mine increases supply, which along with the price - decrease, indicates a market situation where buying can be a good decision. Knowing diamonds are non - renewable and scarce helps in understanding long - term value. Popularity and high demand don't directly explain the timing of the purchase. Cost depends on both supply and demand, not just demand. Satisfaction of wants and needs is a general consumption concept, not specific to the economic decision here.
Answer:
She knew that diamonds are a nonrenewable resource, making them scarce.
