Explain the results of americas improved transportation (trains, steam boats, steam engines)

They made these things to improve how they trade with others. ex. trains are made to export goods to another location

I dont know if that is good enough?

I know that the steam engine allowed transportation to be faster and more productive.

the right answer is the constitution

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life

hope this : )
