Passage Summary: Since we can't win the arms race against rapidly evolving germs, we should switch our focus to teaching people how to avoid catching them in the first place.

Conclusion: The most sensible public health strategy would be to focus heavily on educating the public about how diseases are transmitted to reduce their occurrence.

Reasoning: Microorganisms reproduce so quickly that they evolve immunity to new medicines, making the goal of completely eradicating disease through biochemical research unrealistic.

Analysis: To identify the conclusion, look for the expert's final recommendation. The word 'therefore' acts as a clear indicator that the expert is pivoting from the evidence (germ evolution) to their main proposal (public education). The first two sentences provide the background and the reason why the old strategy is failing, but the heart of the argument is the call for a new strategy based on information and prevention.
