In 1932, the Australian government lost a war against the native emu population. The operation that has since become known as the Great Emu War began as an initiative to combat the overpopulation of the crop-destroying birds invading farmland around Chandler and Walgoolan.
The initial assault on the flightless avians began on November 2 and lasted six days before the military personnel withdrew. Efforts resumed on November 12, but by early December, the feathered foes had adopted guerrilla tactics against the targeted wheat fields, rendering military involvement largely ineffective. The Australian government declined further involvement with the ongoing conflict in 1934, 1943, and 1948, despite the repeated pleas for assistance by the farmers in the area.
Based on the author's support and evidence, which of the following is a valid evaluation of the paragraph?
- A. It is an entertaining piece based on personal opinion.
- B. It is part of a historical account of the Great Emu War in Australia.
- C. It is a detailed analysis of military strategies during the Great Emu War.
- D. It is a scientific report on the impact of emus on the Australian ecosystem.
Correct Answer: B
Rationale: The paragraph provides a historical account of the Great Emu War in Australia, outlining the events, dates, and outcomes of the conflict between the Australian government and the emu population. It does not focus on personal opinion, military strategies, or the scientific impact of emus, making choice B the most accurate evaluation. Choices A, C, and D are incorrect as they do not align with the content of the paragraph.

Studies suggest that more than 9 billion metric tons of plastic have been produced since 1950, more than four times the volume of Mt. Everest, and about 75% of its remains in landfills or has entered the environment as pollution. As a material, plastic has many advantages.
However, it is difficult to recycle because popular single-use and convenience items, such as packaging and water bottles, are low in quality and value when recycled. Part of the magic of plastic is that it seemingly lasts forever. But when it cannot be re-used efficiently, it leads to stark realities like an island of plastic, twice the size of Texas, floating in the Pacific Ocean. Plastic is consumed by fish and birds and is seeping into the air, water, and our food.
Which of the following conclusions can be drawn from the passage?
- A. Plastic pollution poses a significant environmental threat due to its lasting nature and difficulty in recycling.
- B. Plastic is an outdated material with no advantages.
- C. Recycling plastic significantly reduces environmental pollution.
- D. Plastic pollution has no impact on marine life.
Correct Answer: A
Rationale: The correct conclusion that can be drawn from the passage is that plastic pollution poses a significant environmental threat due to its lasting nature and difficulty in recycling. The passage highlights the challenges of recycling plastic due to its low quality when recycled, leading to pollution and environmental hazards. It mentions the presence of a large island of plastic in the Pacific Ocean, showing the severe impact of plastic pollution on the environment. Therefore, choice A is the most accurate conclusion. Choice B is incorrect as the passage mentions that plastic has many advantages despite its recycling challenges. Choice C is incorrect as the passage indicates that recycling plastic is difficult due to its low quality when recycled. Choice D is incorrect as the passage clearly states that plastic consumption by marine life like fish and birds is a reality, showing the impact of plastic pollution on marine ecosystems.
The office memo
To: Staff
From: CEO
Date; June 18, 2021
Subject: Naps Employees,
In the 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 Myles
What source would be most useful in determining the reliability of Punxsutawney Phil's predictions over a number of years?
- A. A memoir from a former president of the Groundhog Club
- B. A record of weather patterns over the past decade
- C. An article on groundhog behavior in the northeast U.S
- D. A historical account of Groundhog Day traditions
Correct Answer: B
Rationale: A record of weather patterns over the past decade would be the most useful source in determining the reliability of Punxsutawney Phil's predictions. By comparing Phil's forecasts with the actual weather outcomes, one can analyze the accuracy of his predictions. Choices A, C, and D do not directly provide the necessary data on weather patterns to evaluate Phil's reliability.
Hedy Lamar was a woman of many talents. She was first known as a European film
actress in the 1930s and early 1940s. Some of her 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, Lamar took up
inventing.
Hedy Lamar 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, Lamar 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 II, 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 Antheil, 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 WiFi. Just think, we might not have any
of those things if Hedy Lamarr had been given more interesting roles.
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.

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 a 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.
When should you redirect your dog's biting behavior?
- A. When your dog bites something inappropriate
- B. When your dog barks at strangers
- C. When your dog is lying down
