Passage Summary: Even though doctors are getting much better at treating people and helping them live longer, the number of people getting serious infections is actually going up.

Reasoning: Medical advances have improved diagnosis and treatment, leading to longer lives and better health, yet serious infection rates have risen significantly over the same period.

Analysis: This stimulus presents a classic tension between general medical progress and a specific negative health trend. To resolve this paradox, we need a factor that explains why better medicine might actually coexist with—or even cause—more infections. Look for an answer that introduces a third variable, such as the idea that longer-lived populations are more vulnerable to infection, or that medical environments themselves have become hotspots for new types of bacteria.
