The most necessary information is how it sank and what happened to the people on it.
Rome was a republic before it was an empire. Romans had the first Senate, elected by the people. The third option is also correct, because even the if the emperor did something that was against the law, he would be put on trial.

Answer:
The executive branch has changed greatly since adoption of the Constitution. Many changes have been the result of constitutional amendments. ... Congress can affect presidential power because while the executive branch enforces the laws, Congress makes the laws in the first place. The Constitution explicitly assigns to the president the power to sign or veto legislation, command the armed forces, ask for the written opinion of his Cabinet, convene or adjourn Congress, grant reprieves and pardons, and receive ambassadors .
