How did empire building benefit farm production?
a. by reducing population pressure
b. by providing more labor resources
c. by expanding trade alliances
d. by making available fertile flatlands
(d my answer)

The answer from the given choices is "B", "Providing more labor Resources".

Empire building benefits farm production by providing more labor resources. As more labor resources means more hands on farm production which ultimately will make the process faster generating more benefits. An empire also allowed people to interact in better ways increasing mutual co-operation.

b) the confederacy had to pay all union war expenses.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
