Question

using the information youve acquired, identify how advances in science led to a longer life expectancy during the industrial revolution. (1 point)
increased wages of factory workers meant that they could afford to pay for doctors and medicines if they became ill.
once it was proven that germs cause disease, governments began to pass laws to improve sanitation in industrial cities.
rapid urbanization stemming from scientific advances in factories led to an increase in hazardous living and working conditions.
people of all classes started to eat more food every day, leading to a longer life

Explanation:

The question is about how scientific advances during the Industrial Revolution led to longer life expectancy. The key here is understanding the role of germ theory. Once it was proven that germs cause disease (germ theory by Louis Pasteur etc.), governments took action. They passed laws to improve sanitation in industrial cities. Better sanitation reduces the spread of diseases, which is a major factor in increasing life expectancy. Other options: increased wages (workers could pay for doctors - but this is more economic, not directly science - led in the context of the core scientific discovery of germs causing disease). Rapid urbanization from factory advances led to hazards (negative for life expectancy). People eating more food (could be due to agricultural changes but not the science - disease - sanitation link as directly as the germ - sanitation - law - life expectancy link).

Answer:

Once it was proven that germs cause disease, governments began to pass laws to improve sanitation in industrial cities.
