A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.
This is kind of an opinion based answer, so ill gove you my opinion. So, before world war 2 there were specific gender roles. After, all the men had to go to war which forced the women to get jibs and work, which wasnt very commin for women. They took on all the hard labor jobs that men had to do. This basically changdd the way women were seen, they are ni longer frail and weak. Also, this brought attention to war and how it is not safe. Esoecially for japanese ppl at the time
The statement that best describes Kennedy's domestic achievements during his time in office is the second one: Kennedy wasn’t able to get much done due to opposition from Republicans and conservative Democrats in Congress.
Kennedy had very progressive legislative programs and reforms in mind, but conservative members from his own party (most of them Southern senators) prevented him from implementing them. He proposed economic reforms, such as increasing the minimum wage and lower the taxes, as well as social reforms, such as providing medical assistance for the elderly and promoting racial integration in the schools, but unfortunately he lacked the support from Congress to fully carry them out - at least while living; after his death, a civil rights bill known as the Civil Right Act of 1964 was passed.
Thomas Jefferson’s belief that government can do only what the Constitution specifically says is known as "express powers".
I hope this helps :)
