Final answer:
The claim that the individual in question became deaf from ear infections, worked in hospitals helping wounded soldiers, and later died of breast cancer is false. Nursing Sister Margaret Lowe served bravely in WWI and died from shrapnel wounds during a German air raid.
Step-by-step explanation:
The statement in the question is false. The description given seems to combine the experiences and unfortunate ends of several individuals. Nursing Sister Margaret Lowe indeed served in the Canadian Army Medical Corps during the Great War and died from shrapnel wounds received during a German air raid in France in May 1918. Her contribution, among many others, was pivotal during WWI, and their sacrifices came at a critical moment in history as Canadian women received the right to vote partly in recognition of women's contributions to the war effort.
Throughout WWI, many nurses like Margaret Lowe served bravely and faced adversity, with at least forty-six dying due to various causes including drowning, disease, and injuries from air raids. After the war, some nurses continued to build careers in medicine, leveraging their invaluable experiences from the war. Others like the acclaimed Elizabeth Smellie continued to serve in military and civilian nursing capacities even into WWII, demonstrating the lasting impact of their wartime service.
