The next day, in the sunday paper, i saw a pitiful closeup photograph of elizabeth, walking alone in front of central on that first day of integration. it pained my insides to see, once again, the twisted, scowling white faces with open mouths jeering, clustered about my friend's head like bouquets of grotesque flowers. it was an ad paid for by a white man from a small town in arkansas. "if you live in arkansas," the ad read, "study this picture and know shame. when hate is unleashed and bigotry finds a voice, god us all." i felt a kind of joy and hope in the thought that one white man was willing to use his own money to call attention to the injustice we were facing. maybe the picture would others realize that what they were doing was hurting everybody. what is the central idea of the excerpt?

She took up a scalpel and slit the monkey's abdomen, making a slow and gentle cut, keeping the blade well away from her gloved fingers. the spleen was puffed up and tough, leathery, like a globe of smoked salami. she did not see any bloody lesions inside this monkey. she had expected that the monkey's interior would be a lake of blood, but no, this monkey looked all right, it had not bled into itself. if the animal had died of ebola, this was not a clear case. she opened up the intestine. there was no blood inside it. the gut looked okay. then she examined the stomach. there she found a ring of bleeding spots at the junction between the stomach and the small intestine. this could be a sign of ebola, but it was not a clear sign. it could also be a sign of simian fever, not ebola. therefore, she could not confirm the presence of ebola virus in this animal based on a visual inspection of the internal organs during necropsy.
