Question

read this part from the text and one from another source. both parts are about dr. rush. these two parts show you that dr. rush
a was infected but felt fine.
b left the city.
c made a mistake.
d was able to save everyone.
excerpt 1
most of the city’s 2,000 free african american residents stayed, too. rush believed, incorrectly, that they were immune to the disease. he enlisted the african american community to help nurse the city’s sick residents. in time, however, the african american volunteers became ill and died, too.

Explanation:

To solve this, we analyze each option with the excerpt:

• Option A: The excerpt doesn't mention Dr. Rush being infected, so A is wrong.
• Option B: The excerpt shows he enlisted the African American community to help, meaning he didn't leave the city, so B is wrong.
• Option C: The excerpt says "Rush believed, incorrectly, that they were immune to the disease" and later the volunteers got sick, so he made a mistake. This matches.
• Option D: The volunteers got sick and died, so he didn't save everyone. D is wrong.

Answer:

C. made a mistake.
