I believe the answer to your question will be that it responds appropriately to the stress.
<span>In the story "Miss Evers' Boys", there is a proposed study to not give antibiotics to a man who could potentially benefit from its use. However, if the antibiotics do not work and the man dies, then others will not want to try it. Nurse Evers objects that there is no formal consent in this proposed study, but she then offers to give the men free rides and meals in exchange for their consent.</span>
I believe the answer is either B. or C.
Hope this helps!
