This is what I know the USSS (United states secret services) is under the agency of the U.S department of homeland security. Until 2003, the service was part of the U.S department of the treasury. This is also what I know the secret service is unique among the federal law enforcement agencies because not only do it's agents provide protection for the President, vice, former presidents, presidential candidates and visiting heads of state and heads of the government.
Hopefully this is helpful.
<span>The correct answer is B. John C. Calhoun of South Carolina. Basically, he believed in nullification becasue he supported slavery, believing it was actually good. He claimed that states shuold have the right to have slaves even if the entire country and the federational government said that they shouldn't. He said that it was a minority right and that each individual state should be observed as a minority.</span>
Caesar Augustus was originally named Octavian, great nephew of Julius Caesar. He was the first emperor of the Rome and was named Augustus. Augustus during this time was known for placing Rome in the "Pax Romana" a state of amazing excellency during ancient Roman times. Since Augustus placed Rome into a period of greatness, it does not make sense that he sent Rome into a civil war, meaning it can't be a. For choice b., it is describing Nero, who supposed played his lyre while the city of Rome burned. Choice d is referring to Julius Caesar; well in partial. Julius Caesar created a calendar but I do not remember if he really referred to himself as a god. So this only leaves option c. He established an imperial government in place of the Roman Republic.
It was an agreement to treat christians nicely/fairly in the Roman Empire, rather than treating them poorly. It was later that christianity became the most popular religion there. Hope I helped :)
