Native American gambling comprises casinos, bingo halls, and other gambling operations on Indian reservations or other tribal land. Since these areas have tribal sovereignty, states have limited ability to forbid gambling there, as codified by the Indian Gaming Regulatory Act of 1988. In 2011 there ended up being 460 gambling operations run by 240 tribes with a total annual revenue of $27 billion
        
                    
             
        
        
        
“We the People of the United States, in Order to form a more perfect
Union, establish Justice, insure domestic Tranquility, provide for the
common defence, promote the general Welfare, and secure the Blessings of
Liberty to ourselves and our Posterity, do ordain and establish this
Constitution for the United States of America.”
Establish Justice:
This was a very important one because the American people wanted make sure they'd have justice under the Constitution.
Domestic Tranquility:
Shays' Rebellion was one of the main reason the Constitutional Convention was held. The people were worried about peace between the nations borders after the rebellion against having to repay war debts. 
Provide for the common defense:
This particular statement said that no individual state could defend itself against attack. It was the whole country's fight. This helped promote unity and a deep love for one's country.
Promote the general welfare: 
The statement said that the government would care for the people's well-being as much as possible.
<span>Secure the blessings of liberty to ourselves and our posterity:
This is one of the most important statements in the entire document. It means that they provide the promise of freedom to ourselves and for our children and their children and so forth.
</span>
<span>Ordain and establish this Constitution for the United States of America:</span>
This last statement of the preamble states that the people made this document as one body and they give the United States its power.
        
             
        
        
        
Answer:
(i) First, it is important to remember the context. America was in the midst of a bloody civil war. Union troops had only recently defeated Confederate troops at the Battle of Gettysburg. It was a the turning point in the war. The stated purpose of Lincoln’s speech was to dedicate a plot of land that would become Soldier’s National Cemetery. However, Lincoln realized that he also had to inspire the people to continue the fight.
Below is the text of the Gettysburg Address, interspersed with my thoughts on what made it so memorable.
Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal.
“Four score and seven” is much more poetic, much more elegant, much more noble than “Eighty-seven”. The United States had won its freedom from Britain 87 years earlier, embarking on the “Great Experiment”. 
(ii) The Emancipation Proclamation and Thirteenth Amendment brought about by the Civil War were important milestones in the long process of ending legal slavery in the United States. This essay describes the development of those documents through various drafts by Lincoln and others and shows both the evolution of Abraham Lincoln’s thinking and his efforts to operate within the constitutional boundaries of the presidency.
