The correct answer is B) The power to ratify changes to the Constitution.
The federal government is given the ability to tax citizens multiple times. This includes Article 1 Section 8 of the US Constitution and the 16th amendment (which establishes the federal income tax).
The power to regulate interstate commerce is also in Article 1 Section 8 of the US Constitution. This was further reinforced by the Supreme Court case Gibbons vs. Ogden.
The US Constitution also explicitly gives the right to sign treaties to the federal government.
This is why B can be the only correct answer.
It can be said that society wants to punish the guilty;however, they are cautious when doing so. Society is afraid that the justice system is placing an innocent person behind bars for every ten people that are being set free. Our judicial system was put in place to protect the innocent and put the guilty behind bars; however, this is not so. We have a corrupt society that contradicts itself from the lowest court system to the highest government powers of Congress. When one political power takes control, it's like a gang or "mafia" take over with the people suffering without a voice.
