Answer:
B- Dr. Dowell will try to find out if the girl and her mother died of bird flu
Step-by-step explanation:
Dr. Dowell, as we see in the paragraphs, is an epidemiologist. This means that he does not have the skills or resources to keep the flu from reaching others.
This also means that he would do no good in seeing if the hospital did something wrong, as he (more than most) knows that there is not much known about this, and he couldn’t do much anyhow.
Option D may be considered, but trust me, it is not the answer. Dr. Dowell is not an ornithologist, and therefore would not be able to “study” the birds because he was not trained for that.
Option B makes the most sense because it is his job, and he can investigate the people rather than the birds or hospital.
