Passage Summary: Money is everywhere, just like language. But since we aren't born with a 'money instinct' and had to invent it, it probably popped up in several different places on its own.

Conclusion: It is likely that the invention of money happened independently within multiple different societies.

Reasoning: Money is found in almost every society, but unlike language, which is an innate human ability, money is a deliberate human invention.

Analysis: The argument identifies a gap between something being 'universal' and it being 'invented multiple times.' The author ignores the possibility of 'diffusion'—the idea that one clever society invented money and then everyone else simply copied the idea. To make this conclusion follow logically, we need a premise that rules out this 'copycat' scenario. Look for an answer that guarantees that if an artificial invention is universal, it must have had multiple points of origin.
