How did Hedy Lamarr contribute significantly to the advancement of technology?

Correct Answer: D

Rationale: The correct answer is D because Hedy Lamarr's invention of a frequency-hopping system, along with George Antheil, laid the foundation for technologies like cellular phones, Bluetooth, and Wi-Fi. This significant contribution revolutionized communication technology. Choice A is incorrect because it focuses on the limitations of the era's technology rather than Lamarr's contributions. Choice B is incorrect as it briefly mentions her collaboration but does not directly relate it to technological advancements. Choice C is incorrect as it highlights her failed inventions, which are not indicative of her significant contributions to technology.

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: C

Rationale: The correct answer is C. The passage does not mention anything about the author's emotional state or preference for concerts. However, it does discuss cicadas and their emergence, life cycle, and behavior. Therefore, the reader can conclude that the author is likely interested in cicadas and their natural history, indicating that they go to the theater as often as possible. Choice A is incorrect because there is no evidence regarding the author being overly emotional. Choice B is incorrect as there is no mention of the author's preference for concerts. Choice D is incorrect as the passage does not provide any information about the author enjoying theater decor.

Correct Answer: C

Rationale: 'After' is used to indicate that one event happened following another in time. In the context of a timeline, 'After' signifies the sequence of events, showing what occurred subsequent to a particular point in time. In the provided extract, events unfold in a specific order, with each event happening 'after' the previous one. Choices A, B, and D do not inherently convey the idea of chronological order and are not suitable for indicating the sequence of events in a timeline.

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.

Correct Answer: D

Rationale: The correct answer is D, an encyclopedia entry about the suspense genre. This choice would be the best source to understand the suspense genre better as it provides a comprehensive and detailed overview of the genre's history, characteristics, and key elements. Option A, a public library's digital catalog, may list suspense novels available but does not offer in-depth information about the genre itself. Option B, online reviews of the genre, are subjective opinions and may not provide a holistic view of the genre. Option C, a New York Times bestseller list, showcases popular titles but doesn't delve into the specifics of the suspense genre.

Correct Answer: B

Rationale: The statement that rested people have better impulse control supports the claim that napping during the workday can lead to employees being happier, healthier, and more productive. Improved impulse control can result in better decision-making, including choosing nutritious food over junk food, which contributes to overall well-being and productivity. Choices A, C, and D do not directly address the relationship between napping and improved well-being or productivity, making them less relevant to supporting the claim.

Correct Answer: B

Rationale: The correct answer is B: 'To inform about Clara Barton's life and achievements.' The passage provides a chronological account of Clara Barton's significant life events, from her birth to her philanthropic work during the Civil War and beyond. It aims to educate the reader about Barton's contributions and accomplishments rather than to express emotions, persuade readers to support a specific organization, or entertain with fictional tales. Therefore, choices A, C, and D are incorrect as they do not align with the informational content of the passage.

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.
