The answer is B. The Dust Bowl, otherwise called the Dirty Thirties, was a time of serious tidy tempests that enormously harmed the nature and horticulture of the American and Canadian prairies amid the 1930s; extreme dry spell and an inability to apply dryland cultivating strategies to avoid wind disintegration.
D. Demonstrations supporting freedom
The Tiananmen Square was a protest in support of political and economic reform.
The fall of the Berlin Wall symbolized the end of communism in Europe and unification.
Nelson Mandela sought out to end apartheid in South Africa.
The US had many attempts at compromise with varying levels of sucess before the Civil War. However, when Lincoln was elected president (on the platform of stopping the expansion of slavery), the South lost hope and seceded.
There is always a solution other than war, however, in this case, war had been a looming possibility for quite some time, and compromise probably would've only pushed the war back a year or two.
Hope this helps :)
