Question

an important development or discovery in science and medicine due to industrialization was
○ salks development of a vaccine that could prevent polio.
○ pasteurs discovery that disease is spread by bacteria.
○ curies development of the process of pasteurization.
○ jenners discovery of a medium for growing and identifying bacteria.

Explanation:

1. Salk's polio vaccine was developed in the 1950s, after the peak of early industrialization, and not directly driven by industrialization.
2. Louis Pasteur's germ theory (that disease is spread by bacteria) emerged in the mid-19th century, a period of intense industrialization. Industrial growth led to overcrowded urban centers with poor sanitation, creating urgent need to understand disease transmission, making this discovery tied to industrialization.
3. Pasteurization was developed by Louis Pasteur, not Marie Curie; this option contains a factual error.
4. The medium for growing bacteria (agar) and related techniques were developed by Robert Koch, not Edward Jenner (who created the smallpox vaccine); this option contains a factual error.

Answer:

Pasteur's discovery that disease is spread by bacteria.
