Correct Answer: D

Rationale: Jorgen should go to the 900 section of the library: History, geography, and biography to find one of the early maps created by Eratosthenes. Eratosthenes, an Ancient Greek mathematician and poet, is known for his contributions to geography and is considered the first person to calculate the circumference of the earth. Therefore, his works on early maps would be categorized under history and geography. Choices A, B, and C are incorrect as they correspond to Philosophy and psychology, Social sciences, and Technical and applied science respectively, which are not relevant to finding maps created by Eratosthenes.

Correct Answer: C

Rationale: The correct answer is C. A gene splicing study report with data is a primary source because it provides original research findings. In contrast, choice A is a secondary source as it involves a critic's interpretation of a book. Choice B, the table of contents of a peer-reviewed scientific journal, is not a primary source but a tertiary source, providing a summary of articles. Choice D, a news article quoting research, is a secondary source that presents information based on primary sources rather than the original research itself.

Correct Answer: B

Rationale: In the context provided, the word 'propagated' indicates that Xavier conveyed or expressed his belief to his friends. 'Expressed' is the most suitable synonym here as it aligns with the idea of communicating a belief clearly. The other options, 'shouted,' 'persuaded,' and 'whispered,' do not capture the essence of spreading or communicating an idea, making them incorrect choices.

Correct Answer: D

Rationale: An automobile with eighteen wheels contradicts the hypothesis that 'All automobiles have only four wheels.' This contradiction reduces the probability that the hypothesis is true. The hypothesis is not proven by the presence of an eighteen-wheel automobile, nor does it raise the probability of the hypothesis being true. Instead, it directly challenges the hypothesis, leading to a decrease in its probability of being correct.

Correct Answer: D

Rationale: The focus of the passage is on Malory and Tennyson and their interpretations of the Arthurian legends. The mention of Charles Dickens in choice D is irrelevant and distracts the reader from the main discussion. While the other choices discuss Malory's prose style, his focus on moral elements, and Tennyson's approach to the Arthurian stories, choice D brings in a comparison to Charles Dickens and his novels about lower-class children in Victorian England. This mention of Dickens does not directly relate to the main theme of the passage, making it the correct answer as the distracting sentence.
