In one paragraph, argue whether U.S. citizens should be required to pass a civil service exam before working in the U.S. government. Support your argument with facts or examples.

American citizens are humans which means that they have different skills and competencies. This means that even though they have the right as citizens to join the government as civil servants, it is imperative that they join the service in a manner that would be most beneficial to the country. This is why Civil Service exams are important. They gauge the skills of the applicants to determine if they would be good fits for the service they would like to join. For example, Shannon is no good at math and financials but applies to the Securities and Exchange Commission (SEC). If there were no civil service exams to test his competence, he might be hired and put in a position he would not be able to contribute to the government's efforts effectively.

Off the coast north Vietnam in the gulf of tonkin;if my memory serves me correct they were about 15 miles off the coast (international waters) 

(an american ship was "attacked";(they claim but no one was sure) off the coast of north Vietnam they think they fired a torpedo at the ship but missed. This enabled the president to take full control of the military and thus putting the U.S into war with Vietnam)
sorry for the long explanation, just trying to help :)
