Hedy Lamarr, the Inventor Hedy Lamarr was a woman of many talents. She was first known as a European film actress in the 1930s. She began starring in American films with MGM Studios in the late 1930s and early 1940s. Some of her more popular films included Boom Town (1940) and White Cargo (1942); however, her roles generally did not include very many spoken lines and she became bored. To relieve this boredom, Lamarr took up inventing. Hedy Lamarr did not have any formal training, but she did not allow that to stop her from teaching herself in her spare time. Although she had a number of failed inventions, such as an improved traffic light and a carbonated drink, Lamarr did not stop coming up with ideas. She even spent time working with the science engineering team employed by Howard Hughes, the aviation tycoon. During World War I, Lamarr learned that one of the military's new technologies, radio-controlled torpedoes, were too easily jammed and redirected. She came up with a type of radio signal that changed, or "hopped, frequencies and was unable to be tracked or disrupted. With the assistance of her friend George Anthell, she was able to design the system and patent it in August 1942. Unfortunately, the United States Navy was not interested. The technology of the era wasn't quite good enough to easily implement Lamarr's system, and the Navy was not particularly interested in civilian inventions at the time. It wasn't until 20 years later, during the Cuban Missile Crisis, that a version of Lamarr's system began appearing on Navy ships. The work Lamarr and Antheil did creating this frequency-hopping system led to many technologies that are often taken for granted today. Their work led to the development of cell phones, Bluetooth, and Wi-Fi. Just think, we might not have any of those things if Hedy Lamarr had been given more interesting roles. Which of the following statements supports the claim that Hedy Lamarr made significant contributions to the advancement of technology?

A. She had many failed inventions, such as an improved traffic light and a carbonated drink

B. She spent time working with the science engineering team employed by Howard Hughes, the aviation tycoon.

C. Her work helped in the future development of cellular phones, Bluetooth, and Wi-Fi

D. The technology of the era wasn't good enough to easily implement Lamar’s system

Answer Explanation:

Her work helped in the future development of cellular phones, Bluetooth, and Wi-Fi clearly shows her significant contributions to the advancing of technology.

Therefore, the Correct Answer is C.

  • Q #2: Research shows that tipping in a restaurant has little to no effect on service. What tipping does do is enable restaurateurs to pay less than the federal minimum wage to servers and depend on customers to make up the difference between servers' salaries and the minimum wage. The U.S. federal minimum wage for servers is $2.13 per hour. Although minimum wage varies from state to state, it is safe to say that customers are paying the lion's share of servers' salaries. This practice leads to resentment on the part of customers, and it devalues servers. It's time to abolish tipping and pay employees a living wage. The result may well be happy servers who provide excellent service to grateful customers.   Which of the following is the writer's main argument?

    A. The custom of tipping should be abolished, and servers should be paid a living wage.

    B. The federal rate for servers is too low.

    C. Servers should provide excellent service no matter how much they make

    D. Customers are resentful of having to help pay the salaries of servers.

    Answer Explanation

    According to the paragraph, it’s time to abolish tipping and pay employees a living wage. The result may well be happy servers who provide excellent service to grateful customers.
