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:

• Salk's vaccine: Developed in 1955 (post - industrialization peak in many countries).
• Pasteur's work: Louis Pasteur's germ theory (disease spread by bacteria) was during the Industrial Revolution (19th century). Industrialization led to urbanization, crowding, and need for understanding disease spread.
• Curie: Marie Curie was a physicist/chemist (radioactivity work). Pasteurization was developed by Pasteur.
• Jenner: Edward Jenner (1796) with smallpox vaccine. The medium for growing bacteria was developed by others (e.g., Robert Koch's agar - based media in the 1880s).

Answer:

Pasteur’s discovery that disease is spread by bacteria.
