Question

when president franklin d. roosevelt showed little inclination to take action on the problem, randolph called for a march on washington by fifty thousand people. after repeated efforts to persuade randolph and his fellow leaders that the march would be inadvisable, roosevelt issued executive order 8802 in june 1941, forbidding discrimination by any defense contractors and establishing the fair employment practices committee (fepc) to investigate charges of racial discrimination. the march on washington was then canceled.
...
president john f. kennedy showed as little enthusiasm for the march as had roosevelt, but this time the black leaders would not be dissuaded.
based on this evidence, what is the meaning of the word \dissuaded\ in this excerpt? (1)

Explanation:

To determine the meaning of "dissuaded", we analyze the context. In the first passage, Roosevelt tried to persuade Randolph and others that the march was inadvisable, and they canceled the march. In the second passage, Kennedy was not enthusiastic about the march, but Black leaders "would not be dissuaded", meaning they were not persuaded to cancel the march. So "dissuaded" means to persuade someone not to do something (like cancel the march, as in the first case).

Answer:

To persuade (someone) not to take a particular course of action (in this context, to persuade the Black leaders not to proceed with the march).
