Correct Answer: C

Rationale: The correct answer is C. The reference to sending a text message in the passage is a clear indication of the 21st century. This action of sending a text message is a modern communication method commonly associated with contemporary times. Choices A, B, and D do not provide any specific details or actions that distinctly tie them to the 21st century. Choice A focuses on the location of an office, which does not inherently place the passage in a specific time period. Choice B uses a metaphorical reference to Medusa, which is a mythological figure not limited to any particular era. Choice D describes a scene involving running to a parking garage, which could occur in various time periods without indicating a specific century.

Correct Answer: A

Rationale: The correct answer is A: 'Witty.' The tone of the passage is light-hearted and humorous, characterized by amusing details like the eccentric birthday party with zebras, monster trucks, and a limited buffet of boiled asparagus and pickled carrots. The mention of Dr. Creekstone planning an even bigger party with more zebras adds to the whimsical and humorous tone. Choices B, C, and D are incorrect as there is no indication of disbelief, hostility, or anxiety in the passage; instead, it conveys a sense of fun and amusement.

Correct Answer: A

Rationale: Choice A provides a comprehensive list of key points from the passage about Dr. Creekstone's 90th birthday party, including the number of guests, unique elements like zebras and monster trucks, the buffet contents, and the fireworks display. Choices B and C do not cover all the important details mentioned in the passage, making them incomplete and inaccurate. Choice D is a partial summary, missing essential details such as the unique elements and the limited buffet, so it is not the best option.

Correct Answer: A

Rationale: The correct answer is 'Predictable' because the author uses it in a negative context to imply something as uninspired or lacking creativity. In the passage, the author mentions that following rules can make writing difficult, contrasting writers who adhere to rules with those who break them to succeed. 'Predictable' reflects a derogatory tone as it suggests monotony or lack of originality. Choices B, C, and D do not convey a derogatory tone in the context of the passage. 'Noisy,' 'Delicate,' and 'Roar' are neutral or descriptive words that do not carry a negative connotation.

Correct Answer: A

Rationale: News articles and textbooks would provide the most relevant historical data on economic trade during World War 1. During significant events like World War 1, news articles would have reported on the economic aspects, such as trade disruptions and policies. Textbooks that cover the period would also delve into the economic impacts of the war. Choices B, C, and D are incorrect because social media, photographs, atlases, works of art, almanacs, and music are less likely to contain specific information about economic trade during World War 1. Social media did not exist during that time, photographs, atlases, works of art, almanacs, and music are more focused on visual, geographical, artistic, or general historical aspects rather than detailed economic data.
