How is Maria's purchase of first-edition books categorized?

Maria's purchase of first-edition books is categorized as investing in an asset because it involves acquiring tangible items that hold value. First-edition books can appreciate over time due to their rarity, historical significance, and condition, making them a form of collectible investment. This type of investment is characterized by the expectation that its value will grow, allowing for potential profit if sold in the future.

In contrast, investing by loaning funds typically involves giving money to someone else for a return, such as through bonds, but does not apply to the acquisition of physical collectibles. Commodities, on the other hand, refer to basic goods used in commerce that are interchangeable with other goods of the same type, such as oil or gold, rather than unique items like first-edition books. Lastly, investing in stocks involves purchasing shares of publicly traded companies and does not relate to collectible or tangible assets like books. Thus, categorizing Maria's purchase as investing in an asset accurately reflects the nature of her investment choice.
