The correct answer to this open question is the following.
One major difference between Ellis’s and Meacham’s historical interpretations of how Thomas Jefferson came to approve the Louisiana Purchase is the following.
For historian Joseph J. Ellis, the issue was the way President Thomas Jefferson proceeded to but the Lousiana territory to the French, knowing that he could have been going beyond his powers as the head of the executive branch. The question for historian Ellis is not that his decision over the territory was right, but the way he implemented that decision that challenged his powers as President. Thomas Jefferson had big hopes that the next step for the American government was in the conquest of the western part of the United States. 
For historian John Meacham, the way President Jefferson acted during the Louisiana purchase saga was decisive, trying to protect the Louisiana territory from the Europeans. Meacham thinks that Jefferson never hesitated to exert his power in this particular and special case to defend the sovereignty of the United States. Probably, in other kinds of decisions, Jefferson would have acted differently, more passively, but not in the case of the Louisiana purchase. 
 
        
             
        
        
        
Answer:
B. It becomes a push factor.
Explanation:
In the mid-1800’s, a large number of immigrants crossed the Atlantic Ocean to begin a new life in America from Europe. More than 3 million of these immigrants arrived from Ireland and Germany. Many of them were fleeing economic or political troubles in their native countries.    
During this time period, technology was developing rapidly. The Industrial Revolution had begun. Larger faster steamships brought people to America by the thousands. Railroads grew and expanded. People could travel quickly and efficiently. Factories were built to produce many new products only recently invented.  
With the rise of American industry, growth of the railroad system created thousands of jobs both in factories and in the construction trade.
