Answer Choices:
Correct Answer:
4.5.1.3.2
Rationale:
4️⃣ She was first known as a European film actress in the 1930s.
💎 This is where Hedy Lamarr’s story begins — her rise to fame as a European film actress in the 1930s before moving to Hollywood.
💎 She gained recognition for her beauty and talent, which eventually caught the attention of MGM Studios in the United States.
💎 Despite achieving fame through films like Boom Town (1940) and White Cargo (1942), Lamarr’s roles often lacked depth or many speaking lines, leaving her intellectually unfulfilled.
💎 This period is crucial because it introduces Lamarr’s boredom with acting, which motivated her to explore new creative outlets such as inventing.
💎 Her early acting career thus serves as the foundation for her later shift toward innovation and science.
5️⃣ During World War II, Lamarr learned that one of the military’s new technologies, radio-controlled torpedoes, were too easily jammed and redirected.
💎 This event represents the spark of her major scientific idea. While living in the U.S. during World War II, Lamarr became aware of a serious problem in military technology: radio-controlled torpedoes could be easily jammed or intercepted by the enemy.
💎 Her curiosity and problem-solving mindset led her to think of ways to make communication signals more secure.
💎 Although she had no formal scientific education, Lamarr taught herself the basics of engineering and radio frequency theory, showing her determination and self-learning ability.
💎 This step marks her transition from being an actress to becoming an inventor motivated by patriotism and innovation.
💎 It laid the groundwork for her most important invention — the frequency-hopping communication system.
1️⃣ She was able to design the system and patent it in August 1942.
💎 After identifying the issue, Lamarr worked with George Antheil, a musician and inventor, to design a frequency-hopping signal system that could prevent torpedo signals from being intercepted.
💎 The system involved rapidly switching communication frequencies, making it nearly impossible for enemies to track or jam the radio signal.
💎 Together, they created a design and officially received a U.S. patent in August 1942, demonstrating her success as a self-taught inventor.
💎 Although the U.S. Navy initially rejected the invention, citing limitations in available technology, Lamarr’s achievement was far ahead of its time.
💎 This marked her most significant contribution to both military communication and modern wireless technology.
3️⃣ It wasn't until 20 years later, during the Cuban Missile Crisis, that a version of Lamarr's system began appearing on Navy ships.
💎 Two decades after her patent, during the Cuban Missile Crisis (early 1960s), the U.S. military finally began to use a version of Lamarr’s frequency-hopping system.
💎 By this time, technological advancements had made her design feasible, allowing it to be implemented for secure naval communications.
💎 This event highlights that Lamarr’s invention was ahead of its time — its practical application had to wait for technology to catch up.
💎 It also underscores how her contributions were initially overlooked due to biases against civilian inventors and women in science.
💎 Nevertheless, her idea played a role in improving military defense systems during one of the most tense periods of the Cold War.
2️⃣ Their work led to the development of cell phones, Bluetooth, and Wi-Fi.
💎 Hedy Lamarr’s and George Antheil’s invention went on to inspire many modern communication technologies that we rely on daily.
💎 The frequency-hopping principle they developed evolved into spread spectrum technology, forming the backbone of Wi-Fi, Bluetooth, GPS, and mobile phone networks.
💎 Her early vision of secure, interference-free communication has shaped the digital age, influencing how information is transmitted globally.
💎 This demonstrates her lasting impact as a pioneer of wireless communication and innovation.
💎 Although she didn’t receive recognition during her lifetime, Lamarr’s contributions are now celebrated, earning her posthumous honors as a trailblazer for women in technology.

Answer Choices:
In 1943, the war in the Pacific raged on. First Lady Eleanor Roosevelt went to rally the troops' spirits, despite the disapproval of military command. Roosevelt planned a grueling itinerary. She visited several islands and hundreds of wounded in her first 6 days. The indefatigable First Lady inspected Navy hospitals, delivered a speech, attended receptions, and visited convalescing officers, all within 12 hours of her arrival. She lifted spirits among the wounded and morale among the troops. She continued her exhausting tour for a month, speaking to every patient in troop hospitals and taking down addresses to contact family members. Roosevelt traveled non-stop, risked her life, and greeted the last patient she saw with the same heartfelt sincerity as the first.Stimulus: 1 of 2Which of the following is a reasonable prediction from the passage?
