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.

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.
