Isaac Newton was creative in his use of prisms to show how white light is actually made up of multiple colors. He used logic in the way he presented his arguments rhetorically in order to convince readers of the correctness of his conclusions.
Newton was not the first to experiment with passing light through prisms to determine how light works. French philosopher Rene Descartes had done prism experiments of his own. But Descartes had thought that passing through a prism actually modified the light in order to produce the color spectrum. Newton correctly understood that when light refracted through the prism, it revealed the range of colors that were naturally in the light. He then used a second prism, blocking all but one color, to show that a single color passing through a prism was not modified in color. He also showed--by positioning the second prism differently--how the multiple colors of light could be recombined into white light again.
Newton's 1672 paper on light refracting through prisms established his reputation as a scientist. He continued to study light throughout his scientific career, publishing a larger work in 1704 on <em>Opticks </em>(as they spelled "optics" then).
Answer:
Instead of coming to terms with each other in a suitable fashion, sectionalism drove each person to be "a member of their state", instead of being a "american". This led to conflicting interests, which boiled down to war. Each person went to war for reasons of their state, instead of what Lincoln wanted, the preservation of the Union.

Option 1:
a.) The US policy of containment stated that they would contain communism to prevent it from spreading into the other countries. This can be seen in the Korean and Vietnam War because the US fought to stop the others from spreading the idea of communism.
b.) The agreements that ended the Cuban Missile Crisis was the idea of open skies. Each country would disarm their nukes and other atomic weapons and allow the skies to be open for “surveillance.” This, however, ended up failing as a US pilot was shot down after “surveying” the skies. The interesting thing about this is that the US president was already getting rid of all the atomic bombs in the US, but told the SU that they were not going to disarm. This scared the SU into disarming.
c.) in my opinion, I believe this containment policy failed. The US was unable to stop communism as it spread to china. The US tried hard to stop this spread but ultimately failed.
Option 2:
a.) The causes of the Korean War include the fear of spreading communism. North Korea were communist and South Korea were not. Just as the US were going through imperialism, North Korea was too. This caused them to want to spread the idea of communism. They attacked South Korea, so the US lead the counter attack and pushed the North Korean forces back.
b.) Due to the lack of support, the US lost the Vietnam war. There were many factors that contributed to this, making the Americans question the real intentions of the war. For example, the Tet Offensive was a turning point in the war. The war was almost over, and Johnson told the public they were winning, but when the US attacked Vietnam on the Vietnamese New year, they lost support. There was a request for 200,000 more troops and the US people saw this as an act of desperation. There was also the My Lai massacre where innocent Vietnamese citizens- mostly children and women- were killed by US soldiers for no reason. This was all covered up by the US government. The war eventually ended when Kissinger negotiated with north Vietnam. The US ended the longest known war and the last few troops leave Vietnam in 1973. South Vietnam surrendered in 1976, which is considered a loss because the US unsuccessfully helped them.
c.) same as option 1
D because it only pertains to animals. A, B, and C is about social pretraining stuff.<span />
The idea of democracy has survived war and oppression because is ideally based on a solid fundamental design. Democracy allows people to determine their political fate by giving them the opportunity to choose their leaders in an election. As such, it allows people to largely control themselves
