Which stage of the dtm is the usa in? a) stage 1 b) stage 2 c) stage 3 d) stage 4

The correct answer is D) stage 4

Stage four is defined by both low birth and death rates due to advances in the production of food, medical advances  and economic prosperity which allows individuals and couples to decide when and if they want to have children. The population increases but only gradually and remains generally stable. Of course, because of immigration from countries which are in a different stage, such statistics vary according to area, social level and ethnic group among other factors.

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.
