Answers

Answer 1

Answer:

Jonas Salk became well known in the early 1950s because he developed a vaccine that virtually eliminated polio from American society.

Explanation:

Jonas Salk was an American physiologist who developed the first polio vaccine.

In 1942 he was awarded a scholarship for the study of a vaccine against influenza that allowed him to collaborate with his former professor and prestigious virologist Thomas Francis, then at the University of Michigan. In 1947, as director of the laboratory for viral research at the University of Pittsburgh, the National Foundation for Infantile Paralysis proposed him to join the different teams that were looking for a remedy for polio. In 1952 he obtained a first result in the form of a trivalent vaccine, for which he used dead viruses by application of formalin.

After testing it with animals and a small population of children who had already developed polio, the good results obtained encouraged the Foundation to finance an extensive test campaign that aroused great public expectation. In 1955 he announced that his vaccine had been successfully tested and immediately became a celebrity, to the point of having to address the nation, at the behest of President Eisenhower, in a televised message.

The first free elections in argentina were held in what year

Answers

Answer:

1983!!!

Explanation:

Final answer:

The first free elections in Argentina took place in 1946 when Juan Perón was elected president, marking a significant shift in Argentine political history away from military coups and fraudulent regimes.

Explanation:The First Free Elections in Argentina

The first free elections in Argentina are widely regarded to have taken place in 1946, when General Juan Perón was elected as president. Before this, Argentina had experienced significant political instability. The elections marked a departure from a series of military coups and fraudulent political practices that had plagued the country. Perón's platform favored labor laws and the workers, gaining him substantial popularity among the urban masses, especially in Buenos Aires. His election followed the military coup in 1943 that overthrew a corrupt regime and during which Perón became the Minister of Labor. Notably, these elections were considered free despite the fact that political competition had been weakened by Perón's regime through various tactics, thus shaping the future of Argentine politics with a mix of populism and authoritarian elements.

Explanation:

what was the goal of trust-busting in the early 1900s?

Answers

To enforce laws to the united states.

Answer:

To impose a regulation on a certain amount of American businesses or definitely dissolve them.

Explanation:

In the last part of the 19th Century and first part of the 20th Century, a big part of the United States went through a process of industralization. As a result, big businesses emerged. Some industries turned to big companies which achieved superiority over their competition by associating with each other, becoming monopolies. This is what trusts are.

Reformers of the Progressive Era considered them to be detrimental for the American economy and its costumers. Since there was no competition, trusts could determine the prices at their own will. So, these Reformers appealed to the law to introduce what it would be known as "trust busting" in order to dissolve them.

Why was the spread of Christianity to non-Jews significant?

Answers

It helped Christianity emerge as a separate faith. :D

At the outset, the emergence of Christianity, preaching by the apostles was recorded only in Israel. Christians were considered a Jewish sect, as another in a series of teachings proclaimed by many prophets and self-taught teachers, healers, and so on. For one of them, Jesus Christ and his teaching were also considered, not as a messiah. According to the Book of Acts, when God appeared to Peter, he ordered him to go to the so-called non-believers, and to preach Christianity. Later, the Apostle Paul took over that role and remained known as the apostle of the non-believers. All this led to the spread of Christianity in much of the world, reaching even to Rome. In this way Christianity has become a separate new faith.

Which of the following people were involved in the Watergate burglary?

Answers

The Watergate burglary was conducted by a group known as the Plumbers, essentially former FBI and CIA agents. Key figures in President Nixon's administration were implicated, and the scandal led to Nixon's resignation.

The individuals involved in the Watergate burglary were part of a group called the "Plumbers". They included former FBI and CIA agents with connections to the Republican Party, aiming to aid the re-election of President Richard M. Nixon. Notably, James McCord, a former CIA operative, was among the burglars. He later became a significant figure in the unraveling of the cover-up.

The Committee to Reelect the President (CREEP), which had sanctioned the break-in, was directly linked to the president himself. Key figures in the Nixon administration knew of and approved the burglary, such as his attorney general John Mitchell, chief of staff H. R. Haldeman, chief domestic advisor John Ehrlichman, and Nixon himself.

The scandal eventually led to intense media scrutiny, the Senate Watergate hearings, and the conviction of several of Nixon's aides for obstruction of justice. This culminated in Nixon's resignation, making the Watergate scandal synonymous with political corruption and abuse of power.

Examples of primary sources would include _____.diaries, Fictional works, Artifacts, Human remains, Scholary work.

Answers

Final answer:

Primary sources are firsthand or original accounts providing factual evidence about an event, person, or period, and include diaries, artifacts, manuscripts among others. They are viewed as the best resources for historians due to the context and wealth of information they provide. Whether a document is a primary or secondary source can depend on its usage context.

Explanation:

Primary sources are original or firsthand accounts, and provide raw data or factual evidence about an event, person, or period. These can include a wide range of documents such as diaries, artifacts, manuscripts, poems, official certificates, speeches, and government documents among others. They are not interpretative but rather provide a direct insight or evidence.

An important point to note is that a document can be a primary source or secondary source depending on the context in which it's used. For example, if Scholar X wrote a biography about Artist Y, the biography would be a secondary source about Artist Y, but a primary source about Scholar X's perspective.

Historians tend to approach textual, or written primary sources with method and scrutiny. They evaluate the author, audience, intent, and context to accurately interpret a primary source document. These sources offer both context and a wealth of information about the period they originated from.
