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.

Office Memo

To: Staff

From: CEO

Date: June 18, 2021

Subject: Naps

Employees,

In recent company-wide audits, many employees have reported fatigue at work. Combined with our acquisition of 10 major projects this year, I'm concerned about our employees' productivity and health.

According to a 2008 study, napping for 60 minutes helped improve verbal memory, motor skills, and perceptual learning better than caffeine. Many successful companies have adopted the practice of work naps, in Industries like tech, manufacturing - even NASA!

Starting today, we will be providing a designated nap room in each office building near the gym and cafeteria to help employees take care of their bodies and minds, so they can be happier, healthier, and more productive

Thank you.

Melinda Vasquez

Which of the following first prompted the CEO to consider implementing nap rooms?

Sometimes, your playful pooch might give a little nip to your hand or something else that shouldn't be bitten. To stop bad biting behaviors, you should attempt to redirect your dog's attention to an appropriate chew toy. You can do this by placing the toy in their mouth and praising them, causing your canine companion to associate chewing on the chew toy with positive emotions. Another step you can take to redirect biting behavior is to use biting deterrent spray. The spray can be homemade or store-bought. Just make sure that the ingredients won't make your puppy's tummy sick!

An Interesting Birthday Party

On Saturday afternoon, local eccentric Dr. Oliver Creekstone held a remarkable 90th birthday party at his countryside estate. Present were 3,000 guests, four zebras, two monster trucks, and a famous bagpipe player from Scotland. Though pleased with the entertainment, attendees reportedly were shocked that the complimentary buffet contained only boiled asparagus and pickled carrots. At nightfall, the party was treated to a stunning and seemingly endless fireworks display. According to our sources, Dr. Creekstone felt that next year's birthday party would have to be even bigger and more interesting. "We'll need at least seven more zebras," he said.

Lexington and Concord

The majority of history scholars agree that the open warfare portion of the American War for Independence began in two small Massachusetts towns: Lexington and Concord. To stop the British from discovering military supplies hidden in Concord, the American Minutemen attempted to stall or halt the British Regulars in Lexington Common.

While the opposing factions were facing off against one another, a shot was fired from an unknown source, causing hostilities to break into violence. After the skirmish at Lexington settled, multiple people from both sides lay dead and the British continued their way toward Concord.

On February 2 of each year, the United States observes the unusual holiday of Groundhog Day, a day of hope that winter is over and spring is beginning. This tradition has been officially observed in the US. since the 1800s, and is believed to have developed from European folk traditions in which a bear, fox, badger, or even hedgehog would serve as the symbolic meteorologist. Although other cultures and towns observe Groundhog Day (or something similar), the town of Punxsutawney, Pennsylvania takes special pride in being home to the one true forecasting groundhog Punxsutawney Phil. At the turn of the twentieth century, townspeople formed the Punxsutawney Groundhog Club to perpetuate the joyful rituals and events surrounding Groundhog Day. Over the years, these events have come to include a scavenger hunt, a talent show, and a ball.

Legend has it that on Groundhog Day the official weather-forecasting groundhog awakens from hibernation and comes out of his burrow to look for his shadow. If he sees his shadow, six more weeks of winter are to come, and Punxsutawney Phil goes back to bed. However, if he does not see his shadow, Punxsutawney Phil takes this as a sign that spring has arrived, and he remains above ground. Of course, common sense tells us that February 2 is too early for spring to begin and that while animals may be attuned to various elements of nature from which humans might learn, they are unlikely to act on their instincts based on a schedule set by a Gregorian calendar. Nevertheless, a visit to Pennsylvania to see Punxsutawney Phil and all of the fun he inspires each year might just provide the touch of hope needed to reach the end of winter

Which of the following evidence from the passage supports the inference that Groundhog Day is an entertaining tradition?
