Answer 1

John Dalton's importance essentially relates to atomic theory. This is a theory to answer the question of what makes up stuff? The question may sound silly, but it has characterized the study of science for thousands of years. Even today, while we 'know' that subatomic particles combine to form atoms which themselves combine to form more complex units, there are many questions that remain unanswered (for instance, what makes up a proton? a quark? etc). Prior to the Age of Enlightenment, there was a dominant theory was called miasma theory, and it posited that diseases were caused by 'bad airs.' This theory was essentially doctrine for the medical sciences until the 1880s when it was replaced by germ theory, the idea that disease is caused by microscopic organisms invading and infecting the body. Now, John Dalton was dead by the time germ theory gained notoriety, but the concepts in his work are largely the same: rather than stuff being made up of aether, soul, black bile, or whatever, Dalton's work led to an early understanding of the building blocks of physical matter. This story is further significant in the history of intellectual thought because it characterizes the shift that occurred during the Age of Enlightenment and Scientific Reason, the shift from trusting received knowledge to testing and experimenting using established scientific principles that can be recreated and retested to explore a hypothesis.

This leaves you with the task of synthesizing a response regarding Dalton's importance to the specific times and places mentioned, but it should give you a jumping off point to get started. I hope it helps!
