Hello. You forgot to mention that this question is about the article "The legacy of Charles R. Drew."
Answer:
Paragraphs 5 and 6 not only show that Drew created an efficient method of storing blood, but also created the possibility for blood to be stored and transported throughout Europe, to help injured soldiers during the fighting of the First World War.
Step-by-step explanation:
The article "The legacy of Charles R. Drew", shows how Charles R. Drew, in addition to being a great doctor, built a strong legacy in health related sciences. This is because the text shows how Drew was an exemplary student, able to graduate from medical school with little financial resources, in addition to showing his influence on techniques for storing blood.
This is because the text shows how important blood storage is, but it was very difficult for the stored blood to be used again.
Paragraphs 5 and 6 of the article show how Drew found that storing blood plasma was very efficient and could end storage problems, so he built a blood storage technique and even established a way to send blood from the USA to Europe, where blood could be used to save the lives of soldiers injured in the first world war.
