Why was Lamarr's invention not of interest to the US?

A. Hollywood was known to have spies B. The navy preferred to use the work of military engineers C. The military was too preoccupied to consider new inventions D. They suspected her patent was invalid

Correct Answer: B

Rationale: The correct answer is B. The US Navy preferred to utilize technology developed by military engineers rather than consider Lamarr's invention. Choice A is incorrect because Hollywood containing spies is not relevant to why the US was not interested in Lamarr's invention. Choice C is incorrect as there is no mention of the military being too preoccupied to consider new inventions in the provided context. Choice D is incorrect as there is no indication that the US suspected Lamarr's patent to be invalid; rather, the focus was on the navy's preference for technology developed by military engineers.

Question 2 of 5

Which of the following lines from the passage supports the inference that Hedy Lamarr worked earnestly to achieve her goals?

A. She began starring in American films with MGM studios in the late 1930s and early 1940s B. She even spent time working with the science engineering team employed by Howard Hughes, the aviation tycoon C. Her roles generally did not include very many spoken lines and she became bored D. ... but she did not allow that to stop her from teaching herself in her spare time.

Correct Answer: D

Rationale: The correct answer is D, as it showcases Hedy Lamarr's determination and hard work towards achieving her goals. Despite facing challenges, such as not having many spoken lines in her roles, she persevered by teaching herself in her spare time. Choice A talks about her success in starring in American films but does not directly relate to her working earnestly. Choice B mentions her collaboration with Howard Hughes' science engineering team, which indicates involvement but not necessarily hard work towards personal goals. Choice C describes her becoming bored due to the lack of spoken lines in her roles and does not highlight her dedication and effort to achieve her aspirations.

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

A. The technology of the era wasn't advanced enough to easily implement Lamarr's system B. She collaborated with the science engineering team employed by Howard Hughes, the aviation tycoon C. She had several failed inventions, such as an improved traffic light and a carbonated drink D. Her work led to the future development of cellular phones, Bluetooth, and Wi-Fi.

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.

Question 5 of 5

Which of the following additional pieces of information supports the claim that napping during the workday will help employees 'be happier, healthier, and more productive'?

A. In 1999, National Napping Day was founded in response to Daylight Saving Time B. Rested people have better impulse control, so they are more likely to choose nutritious food over junk food C. Multiple companies have designed special seats or pods specifically for getting the optimal workplace nap D. A study showing that the best time of the day for a nap is between 2 and 3 p.m.

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.
