Explanation:
The aggregate demand curve is downward sloping. It implies price levels are falling and the quantity of output will increase as well as the domestic income. The theories that can explain why the aggregate demand curve is downward sloping: the Pigou's wealth effect, the Keynes's interest-rate effect, and the and Mundell-Fleming's exchange-rate effect.
The answer should me d if I’m not mistaken
A). Food and Drug Administration (FDA)
-The FDA was established around the early 1900s (06') after health problems between production and regulations of factory processed food [and drugs], mostly on the process of meat. (I remember learning this in US History, they blended rats along with human fingers in some of the meat, selling it to people. The book: "The Jungle" also caused this act to come in place)
-I didn't mean to go into history of this lol
The other answers would not make sense as their mission focuses on other regulations.
Hope this helps :)
