The articles of confederation

did reflect the principle "separation of powers" because it made a legislative branch and a strong executive
did reflect the principle "separation of powers" because it made three separate branches of government
did not reflect the principle "separation of powers" because it did not create a separate judicial branch
did not reflect the principle "separation of powers" because it only created a single legislative branch

can someone me with this question:  

1) the end of the conflict between the north and the south didn’t just mark the end of a war; it marked the end of an entire way of life.” which statement best describes what this statement means?  

a) the southerners were no longer free and were controlled by the northern states.

b) the industrial economy in the north was not sustainable.

c) slavery became illegal, which changed completely the south’s labor force and the agricultural economy was destroyed.

d) the states decided to relinquish their independence and return to britain’s rule.    

i don't really understand the question
