To determine which of the sentences would be considered plagiarism without citing Isaacson's work, we need to analyze how each sentence relates to the original passage and whether it presents unique ideas or commonly known facts.
A. "When you first see the walls and pyramid at Saqqara, you may think they are a mirage. But they are not."
- This paraphrases Isaacson's idea about the visual impression of the pyramid and walls but does not use his exact wording. However, it closely follows the structure and concept of the original passage, which makes it potentially problematic without a citation.
B. "The great pyramid of Saqqara was built by the Egyptian king Zoser."
- This statement includes unique information about the construction of the pyramid and the identity of the king, Zoser. It is derived directly from Isaacson's text, so it would also be considered plagiarism if not cited.
C. "The pyramid at Saqqara was built over 4,600 years ago."
- This information is specific and was directly taken from Isaacson’s work, making it not common knowledge. Thus, it would also be considered plagiarism without proper citation.
D. "Saqqara is about an hour outside of Cairo."
- While this statement presents location information, it is general enough to be considered common knowledge that could be easily verified in various sources. Therefore, it would not necessarily be considered plagiarism without citation.
In summary, sentences A, B, and C would be considered plagiarism if Isaacson's work was not cited, while sentence D likely would not.
