You are preparing a speech on the importance of donating

blood. What types of sources would be the most useful and
what types would be the least useful?

What will be an ideal response?

I would probably steer clear of books because the information in them is often
outdated and it takes quite a while to read through to get the needed information.
Newspapers and magazines might be a good source to find examples and peer testimony. I
could go by the Red Cross and see if they have any newsletters or other information they
hand out. I could access the Red Cross online as well and look for facts, examples, and
various types of testimony. Although the information is often very technical, I might find
some useful information in medical journals such as facts and expert testimony.
