I do not understand what exactly your question is but,
The 3 branches are the <u><em>Executive</em></u> branch, <em><u>Legislative</u></em> branch, and <em><u>Judicial</u></em> branch.
The <em>Legislative</em> branch <em>makes the laws</em>.
The <em>Executive</em> branch <em>enforces laws or put them in action</em>.
The <em>Judicial</em> branch <em>passes the law</em>.
This separation is called <u><em>"The Separation of Powers"</em></u>.
The delegates did decide to revise them. They were ineffective and couldn't unite the country.
Answer:
<em>C. The US had a military base at Guantanamo Bay. </em>
<em>D. The US had many economic interests in Cuba</em>.
Explanation:
It's not A because let's be honest, that's a very dum answer
It's not B because that's an even more dum answer
So since there is more than one answer, it would be both C and D.
C because the US till this day has a military base in Cuba called Guantanamo Bay, where they send criminals.
D because Cuba was like "America's Playground" as it was controlled by them prior to their independence. Considering how close it was, it would be a good trading point.
Hope this helped m8!
