At different times in history the national security council has acted as both a line and a staff agency give evidence to support this statement

The National Security Council was created by the National Security Act of 1947 and started functioning in September 1947.

Line agency is when the Congress and the president set goals and to accomplish the agencies help them. Staff agency is when the council offers advice and assistance to the chief executive and other administrators.

An example of the use of the NSC as a line agency is the fight against terror after the attacks of September 11, 2001, when the agency had the authorization to kill individuals who were suspected terrorists.

An example of the use of the NSC as a staff agency is when they advice the president and help him manage international crisis, such as declarations of war.

brainliest is someone you pick by simply clicking a button. it only shows up if there are two people that answered your question, then you decide who answer more accurately with detail and explanation and you give that person the title "brainliest".

i hope this your understandings.

athenian democracy developed around the fifth century bc in the greek city-state (known as a polis) of athens, comprising the city of athens and the surrounding territory of attica, and is often described as the first known democracy in the world. other greek cities set up democracies, most following the athenian model, but none are as well documented as athens'.

it was a political system of direct democracy, in which participating citizens voted directly on legislation and executive bills. participation was not open to all residents: to vote one had to be an adult, male citizen, i.e., not a foreign resident, a submissive or a woman, and the number of these was "probably no more than 30 percent of the total adult population."[1]

the longest-lasting democratic leader was pericles. after his death, athenian democracy was twice briefly interrupted by oligarchic revolutions towards the end of the peloponnesian war. it was modified somewhat after it was restored under eucleides; the most detailed accounts of the system are of this fourth-century modification rather than the periclean system. democracy was suppressed by the macedonians in 322 bc. the athenian institutions were later revived, but how close they were to a real democracy is debatable. solon (594 bc), cleisthenes (508/7 bc), and ephialtes (462 bc) contributed to the development of athenian democracy. cleisthenes broke up the power of the nobility by organizing citizens into ten groups based on where they lived rather than on their wealth.

hope this !
