Question

prior to the eighteenth century, doctors believed that a person suffering from a chronic illness had an imbalance of body fluids. as a result, they would remove some of the patient’s blood to even out the fluids in a process called bloodletting. which statement most likely describes a way that modern societal decisions were impacted by the scientific research of eighteenth - century doctors? bloodletting was proven to prevent illnesses and is widely used now. bloodletting was shown to be unhelpful and was discontinued. doctors used to believe that bloodletting was helpful. doctors continue to do much research on bloodletting.

Explanation:

The passage states 18th-century doctors used bloodletting because they believed it fixed fluid imbalances. Modern science would have shown this practice was not effective, so it was stopped. The other options are incorrect: bloodletting is not used now, doctors then thought it helpful (not that research proved it), and they did not research it in a modern scientific way.

Answer:

○ Bloodletting was shown to be unhelpful and was discontinued.
