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:

• Option 1: Improvements in blood handling would likely reduce deaths from incorrect blood typing, not increase, so this is wrong.
• Option 2: Better blood handling (e.g., storage, typing, transfusion) would improve survival rates for injured soldiers, including those who lost limbs, allowing more to return home. This makes sense.
• Option 3: Improvements in blood handling should improve storage techniques, reducing the need for more donations due to poor storage, so this is incorrect.
• Option 4: Blood handling improvements are related to medical care for soldiers, not directly to organizations speaking against the war. This is irrelevant.

Answer:

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