Which of the following is a logical conclusion that can be derived from the announcement above?

Correct Answer: C

Rationale: The correct answer is C. The fee imposed by the library is likely intended to discourage patrons from spending excessive time on the computers, ensuring fair usage of limited computer resources. This measure is implemented to promote equal access to all visitors. Choice A is incorrect because the purpose of the fee is not primarily to generate additional revenue but rather to regulate computer usage. Choice B is incorrect as the fee is not meant to encourage more efficient computer use but rather to limit the duration of use. Choice D is incorrect as the main goal of the fee is not to cover maintenance costs but to manage computer access.

Correct Answer: C

Rationale: The author's tone in the passage is matter-of-fact. The text provides practical suggestions and advice in a straightforward manner, focusing on actions without expressing emotions or bias. Choices A, B, and D are incorrect because the author does not show signs of being optimistic, pessimistic, or angry; instead, the author presents information objectively and neutrally.

Correct Answer: A

Rationale: The correct answer is A: '100.' Freud's theories fall under psychology, which is classified under the 100 section according to the Dewey Decimal Classification system. Section 200 is for Religion, 300 for Social sciences, and 900 for History, geography, and biography. Therefore, A is the most appropriate section for Lise to find research material related to Freud's psychological theories.

Correct Answer: C

Rationale: The correct answer is C: 800. Greek mythology and literature are typically found in section 800 of the library classification system, which includes works like Oedipus Rex by Sophocles. Choice A (300) pertains to social sciences, choice B (400) covers languages, and choice D (900) focuses on history, geography, and biography, making them incorrect for finding a play like Oedipus Rex.

Correct Answer: A

Rationale: The correct answer is A. Mara's data sample is biased because it only includes teachers who are immersed in the technology field, specifically those teaching a computer software course. This limits the perspectives gathered, leading to skewed results. Choice B is incorrect because the issue lies in the sample composition, not its size. Choice C is incorrect as a large sample size does not necessarily indicate bias. Choice D is incorrect as the sample's bias compromises the study's validity.
