Question

which was most likely an effect on society that resulted from improvements in blood handling during world war i and world war ii?
○ more soldiers died as a result of incorrect blood typing.
○ more soldiers who had lost a limb returned home.
○ more donations were needed as a result of poor storage techniques.
○ more organizations spoke out against the war.

Explanation:

Improvements in blood handling (such as better blood - typing, storage, and transfusion techniques) during the World Wars would have led to better medical care for soldiers. This would mean that soldiers who might have died from blood - related issues (like incorrect blood typing leading to transfusion reactions) were saved. Also, better medical care in general (which blood handling improvements are a part of) could mean that soldiers who lost a limb (but survived due to better overall medical care including blood - related aspects) could return home. Incorrect blood typing deaths would decrease with improvements, not increase. Improvements in blood handling would imply better storage techniques, not more donations due to poor storage. And blood handling improvements are not directly related to organizations speaking out against the war.

Answer:

B. More soldiers who had lost a limb returned home.
