Anthrax is a rare bacterial disease spread by animals, insects, and mosquitoes. Victims may feel ill or have skin ulcers and difficulty breathing. I believe that you can find how it was used in a (story I believe in your case) by trying to find its significance of it to the story. Try to imagine what the story would be like without it? Does it change the ending?
Hope this helps!
<span>The correct answer is B. Pulmonary. The answers C. Cerebral and D. Extremity, are baseless regarding this question; A. Systemic could be a good alternative, as the blood flows from the systemic to the pulmonary circulation in the right side of the heart; but the systemic circulation is in fact mostly handled in the left side of the heart, while the right side handles the pulmonary one. </span>
