The correct answer is A) They had differing ideas about a powerful national government.
After the Revolutionary War, states were consistently worried about the power of the national (central) government. Considering that one of the biggest reasons for breaking away from England was a tyrannical central government, helps to understand why there were differing ideas about the structure of the American govenrment when the US became independent.
This is why the United States, under the Articles of Confederation, had a small and weak central government. Some states liked this while other states felt that this central govenrment was too weak to function effectively.
If you're talking about factories back in the day…
Think of the Industrial Revolution. ESPECIALLY in England. People were flocking to big cities where factories were so they could get jobs. This caused over population and a lot of struggle.
Factories were overcrowded, dirty, and very "harsh". Children were a big issue during this time because owners used them for work and they were so young. There were a lot of injuries, fires, and such because of just the lack of control in factories.
Now a days, we have learned from our mistakes and made factories cleaner and MORE ORGANIZED.
