Answer:
President
Explanation:
Here, George Washington is referred to as the first president of the United States—that is, the first in a number of presidents of the United States. Thus, in that example, president is a common noun.
A complex sentence has a main clause and a dependant or subordinate clause right after, joining the two is subordinate conjunction.
Example:
You should always contribute to society since it will improve the lives of many people.
(You should always contribute to society) main clause.
(Since) subordinate clause
(Since it will improve the lives of many people)
dependent clause
