Passage Summary: Since things like gold and feathers were jewelry before they were cash, it makes sense that beads followed that same pattern.

Conclusion: It is logical and expected that beads, which were first used for decoration, eventually became a form of currency.

Reasoning: Historically, many other items used as money—such as gold, silver, and feathers—were also used primarily for decoration before they were used as currency.

Analysis: The argument relies on an analogy: because X, Y, and Z followed a certain path, it is 'natural' for A to follow that same path. To justify this, we need a principle that turns this historical observation into a general rule. Look for a principle that connects 'initial decorative use' to 'suitability for currency.' The best answer will likely state that being valued for adornment is a sufficient condition or a standard precursor for an object to function as money, thereby bridging the gap between the examples and the conclusion about beads.
