For this case we have the following dialogue:
 Elena: ¿De dónde eres Carlos?
 Carlos: Soy de Cuba y mis compañeros son de Estados Unidos. ____________________ son (They are) de Texas.
 We note that we must translate the expression in parentheses to fill in the blank.
 The expression in parentheses represents the third person of the plural.
 For this case, the third person in the plural is male.

 Elena: ¿De dónde eres Carlos?
 Carlos: Soy de Cuba y mis compañeros son de Estados Unidos. Ellos son (They are) de Texas.
