I think that it is after the salutation or before the closing of the letter. If it were a letter, it would look like this:
Dear Dr. Doctor,
(Dear is the Salutation). Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter. Body of letter.
Sincerely,
Brainly
Ok let me see what I got here.
For number 1 the correct option is the second one. Jose Marti's writing and political theories defend democracy.
Now for the second question the answer is no one beacuse actually NO One lives on Cayo santa maria.
And for the third question the correct answer is the option number 1: He established relationships with other Cubans who dreamed of independence. I hope this can help you greatly
