Passage Summary: Money is basically a tool for buying things. Just as a hammer is useless if you don't have anything to build, money is useless if there's nothing available to purchase.

Conclusion: Money is useless if there are no goods or services available for purchase.

Reasoning: The argument relies on an analogy where money is compared to a tool; since a tool's value depends entirely on having a task to perform, money's value must depend on having things to buy.

Analysis: This is a 'Complete the Argument' question based on a simple analogy. To find the right answer, you need to extend the logic of the tool metaphor to the concept of money. If the defining characteristic of a tool is its utility in a task, and money is 'like' a tool, then money's utility must be tied to its 'task'—which the stimulus identifies as purchasing things. Look for an answer that mirrors the 'useless without a task' condition for money.
