The polio vaccine developed by Jonas Salk avoided hundreds of new polio cases in a country that had become used to the disease's ravages. Because children were vaccinated against the sickness, the invention was a tremendous breakthrough that impacted Americans throughout the country. Unfortunately, a tiny number of children were infected with polio due to Salk's vaccine; nevertheless, this impact was minor compared to the disease's near extinction in the United States. Even though Salk's approach to introducing the vaccine ruffled some of his scientist colleagues' feathers, it did not spark a considerable public debate about the media and science.
Cotton was elevated as a base of the Southern economy thanks to Eli Whitney's creation of the cotton gin, a system for quickly extracting cotton seeds from cotton fiber. Instead of smaller cotton plantations, the invention resulted in larger cotton plantations. The United States did not need to import cotton; rather, after the creation of the cotton gin, the country became a major cotton exporter. Larger plantations necessitated more enslaved people. Therefore the cotton gin expanded rather than decreased reliance on slave labor.
As the leader of the executive branch, the President has the power to veto legislation passed by Congress. It is a necessary check on the legislative branch's legislative power. Congress can overturn a presidential veto with a 2/3 majority vote in both the House and Senate.
The Federalist Party supported a pro-British foreign policy, unlike the War of 1812. Many Americans disliked the Federalists because of this, and this dislike grew when the war ended in victory for the United States. Although the Federalist Party supported a strong central government, this was not a major cause of the party's demise. In states such as Connecticut, Delaware, and Maryland, the Federalist Party created state political parties. As many members were well-to-do businesspeople, the Federalist Party was pro-trade and pro-business.

The state of Louisiana's constitutional authority to provide "separate but equal" accommodations on railway lines within the state was upheld by the United States Supreme Court in Plessy v. Ferguson. The judgment established a legal foundation for racial segregation in American culture, including segregation in schools and other government services. The ruling's main purpose was to confirm the alleged legitimacy of segregation, not to reinforce state rights. The decision had increasingly major ramifications as America's culture became more segregated. Poll taxes and railway strikes were not discussed in Plessy v. Ferguson.
The 1944 G.I. Bill provided several important advantages to American veterans. Economic aid for veterans attending education, housing subsidies, and unemployment compensation was among them. Over a million veterans took advantage of the opportunity to attend college, and the G.I. Bill helped many families build houses. The availability of higher education and the rise in homeownership contributed to the emergence of a new middle class. The Bill did not include special incentives for veterans to stay in the military after WWII. It did not provide veterans with free housing. Finally, the Bill did not give veterans preferential treatment in the workplace.
Although the president supervises the conduct of the war, only Congress can declare war. It is an example of the US Constitution's separation of powers clause.
Because scientific writings were produced and circulated throughout Europe, Johann Gutenberg's printing press increased scientific understanding and advancement. Because such texts were distributed outside of Germany. Gutenberg Bibles were produced using Gutenberg's press, hence his invention was most likely a factor in the Catholic Church's Reformation. In reality, the printing press was used to produce Martin Luther's Ninety-Five Theses (against the Catholic Church). On the other hand, this reformation occurred in tandem with scientific progress rather than in place.
