What do scientists do? o a. they use their knowledge to make public policy o b. they make sure all facts fit scientific theories. o c. they make ethical decisions for the government o d. they learn about the world through observation.

Considering there are different fields of science and many career involving the matter, I'd say that option D. They learn about the world through observation. makes the most sense in this scenario.

I hope this helps! :)
