German paper marks rapidly lost value between 1918 and 1923

Explanation:

Between the period 1918 ans 1923, the German economy crumbled rapidly and it had enormous inflation, resulting in large scale poverty in the country. This can be seen very well from the presented graph, as at 1918 one paper Mark was almost equivalent to one gold Mark. Then as the years pass by the paper Mark starts to lose on value, and by 1921 it is almost 1,000 paper Marks that were the equivalent of one golden Mark. From 1922 we have a sharp loss of value of the paper Mark continuing in the next 1923, with the end result being one billion paper Marks to be equivalent to one gold Mark.

overtime, the civil rights movement changed in a way that not only it benefited african-americans, but benefited other ethnicity's such as latinos, asians, or women too! that's why the results of the movement be called mixed.

the civil rights movement brought about tremendous changes. no longer were blacks denied the right to vote, to eat, shop, and swim where they , and more importantly, to attend integrated schools. despite its many accomplishments, however, the civil rights movement had its shortcomings. for example, many people, both young and old, lost their lives, homes, jobs, and families. still other individuals were so damaged by psychological trauma that they ceased being productive members of the community. the movement left intact the economic inequities that had contributed to the maintenance of segregation. and finally, racism remained alive and well long after the movement's end. like most movements of its kind, the civil rights movement left behind a mixed legacy of triumph and tragedy.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
