How did civil rights expand in the 20th century?

correct sequence:

a) soviet leader nikita khrushchev denied the existence of missiles in cuba.   (already in september, 1962, khrushchev warned the us against attacking any supply ships the ussr brought into cuba and denied the presence of any offensive weapons.)

c) a us reconnaissance plane discovered missiles being installed in cuba.   (the discovery was made october 15, 1962.)

e) us president john f. kennedy ordered the us navy to form a barrier around cuba.

f) us president john f. kennedy demanded an end of the secret operation.   (in an october 22, 1962, speech, kennedy announced to the nation the naval blockade he had ordered and announced to the soviet union his demand that they stop their operation and remove their missiles.)

d) us president john f. kennedy promised to not invade cuba and to dismantle us   missiles that were installed in turkey.

b) soviet leader nikita khrushchev offered to dismantle the missiles in cuba in exchange   for certain promises from the united states.

the cuban missile crisis was a tense face-off between america, led by president john f. kennedy and the soviet union, led by nikita khrushchev, in october of 1962, over the placement of soviet missiles on the island of cuba, close to the united states home territory.   it is often stated that this moment was the closest the usa and the ussr ever came to the eruption of an actual nuclear war between the two superpowers.

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."

an economic reason that the south needed a reconstruction plan is that plantations, factories, and other businesses were destroyed during the war.
