Passage Summary: The author argues that because aspartame is more potent than sugar, drinks made with it are sweeter, leading drinkers to crave high levels of sweetness.

Conclusion: People who drink aspartame-sweetened soft drinks will eventually prefer products that are extremely sweet.

Reasoning: Aspartame is sweeter than sugar by weight, and since sugar-sweetened drinks are sweet, aspartame-sweetened ones must be even sweeter.

Analysis: The argument suffers from a classic part-to-whole flaw, assuming that because an ingredient is more intense per gram, the final product must also be more intense. It fails to consider that manufacturers might simply use much less aspartame to achieve the same level of sweetness as sugar. When looking for a parallel, seek out an argument that assumes a concentrated component necessarily results in a more concentrated final mixture, regardless of the quantity used. It's like saying a drop of ghost pepper sauce makes a gallon of soup spicier than a cup of mild salsa—it depends entirely on the proportions.
