Explain why the writers of two (2) of the scenerios below were right or wrong in their decisions to cite or not to cite sources:

1. Shakespeare died over 400 years ago. So, Hiram inserted a quote by Shakespeare from the play Hamlet into an essay without using quotation marks or citing the reference.
2. Beattie noted in his history paper the fact that representatives from the 13 British colonies signed the United States Declaration of Independence in 1776, but he did not cite a source for the information.
3. When taking notes about the American Revolution, Sara found a quote of Benjamin Franklin’s words, which she paraphrased. She inserted it into her paper without quotation marks or a reference to Benjamin Franklin.
4. Jeffery wrote a paper on popular music in which he claimed that many songs came from earlier sources. He included the entire song lyrics from the Beatles and compared them to the lyrics of a song by a folk singer from the 1930s. He cited the Beatles. Although he included the lyrics from the 1930 song, he did not include a reference to the source.
