Correct Answer: D

Rationale: The event that occurred fourth on the timeline was starting a school for the deaf. Looking at the provided extract, we can see that the order is significant when discussing a timeline. Out of the given events, founding a school for the deaf would come fourth in chronological order. 'Helped found National Geographic Society,' 'Developed a metal detector,' and 'Moved to Canada' would precede starting a school for the deaf in a chronological timeline, making them incorrect choices.

Correct Answer: C

Rationale: The announcement states that the university polled the various departments about schedules to determine a recommended roster for each department to visit the canteen for lunch. This indicates that the university checked to see when the most faculty members from each department would be entering the canteen to offset the crowding issue. Therefore, the correct choice is C. Choices A, B, and D are incorrect because there is no mention of arranging the schedule alphabetically, checking with departments in advance for agreement, or simply establishing different times without considering faculty members' schedules in the announcement. The university's approach was to tailor the lunch schedule based on each department's peak entry times to manage the crowding problem effectively.

Correct Answer: D

Rationale: A fable is a short story that typically features animals, fantastic creatures, or other forces within nature as characters. These characters often possess human-like qualities and behavior, and the story is intended to convey a moral lesson or message to the reader. The use of animals or other natural elements is a common characteristic of fables, distinguishing them from other types of stories or literary works. Options A, B, and C are incorrect because they do not accurately describe the defining characteristics of a fable.

Correct Answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.

Correct Answer: D

Rationale: The correct answer is D. Frost's poem emphasizes that opting for less conventional paths in life adds depth and meaning.
