A food chain is a diagram used by biologists to better understand ecosystems.
It represents the interrelationships between different plants and animals. The
energy is derived from the sun and converted into stored energy by plants
through photosynthesis, which travels up the food chain. The energy returns
to the ecosystem after the organisms die and decompose back into the Earth.
This process is an endless cycle.
In food chains, living organisms are grouped into categories called primary
producers and consumers, which come in multiple tiers. For example,
secondary consumers feed on primary consumers, while tertiary consumers
feed on secondary consumers. Apex predators are the animals at the top of the
food chain. They are the highest category consumer in an ecosystem, and apex
predators do not have natural predators.
What would a mongoose likely eat according to the food chain diagram?
- A. Shrub
- B. Aardvark
- C. Vulture
- D. Mouse
Correct Answer: D
Rationale: According to the food chain diagram, mongooses are consumers that feed on smaller animals like mice, making choice D the correct answer. Shrub (choice A) is a plant and not a typical food for mongooses. Aardvark (choice B) is a large mammal that is not a primary food source for mongooses. Vulture (choice C) is a scavenger bird that typically feeds on carrion, not a preferred food for mongooses.

Starting in 1856, Alfred, Lord Tennyson began publishing his compilation of Arthurian legends that became known as Idylls of the King. these poems were based on the earlier medieval collection Le More of Arthur, by Sir Thomas Malory, which dated to the middle of the 15th century. Malory's work, which is believed to be largely a translation of older French stories, was written in prose style. It combine date earlier tales into a single grouping for English readers. As the title suggests, Malory's focus was largely on the epic nature of Arthur's life. Malory also included chapters on knights such as Lancelot and Gareth, and he discussed the relationships between Tristan and Isolde, and Lancelot and Guinevere. Instead of embracing the romance angle, however, Malory focused more on the moral elements within these stories. Tennyson, though heavily influenced by Malory, took a different approach to the Arthurian stories. For one, he wrote them in poetry form, not prose. Additionally, Tennyson, as a Victorian poet, was more interested in the romantic qualities of the stories, and included the distinct elements of nature and elegy. Idylls of the King has a softer focus overall. For Instance, in Malory's work, Guinevere faces execution for her adultery, and is only spared when Lancelot rides in to rescue her. In Tennyson's work, Arthur chooses to forgive Guinevere, and she chooses to spend the rest of her days doing good works in a convent. some literary scholars believe that Tennyson was writing an allegory about social problems and the need for social justice that existed during Tennyson's own time. Charles Dickens is remembered for doing the same thing in his novels about the abuses of lower-class children in Victorian England.
Which of the following is not identified as a difference between the two authors?
- A. Malory wrote prose, while Tennyson wrote poetry.
- B. Malory wrote during the medieval era, while Tennyson wrote during the Victorian era.
- C. Malory was more focused on heroism and morality, while Tennyson was more focused on nature and elegy.
- D. Malory wrote stories about Gareth, Tristan, and Isolde, while Tennyson focused only on Arthur, Lancelot, and Guinevere.
Correct Answer: D
Rationale: The passage explicitly mentions that Malory included chapters on knights such as Lancelot and Gareth, and he discussed the relationships between Tristan and Isolde, and Lancelot and Guinevere. This shows that Malory did focus on a wider range of characters beyond just Arthur, Lancelot, and Guinevere. Therefore, the difference mentioned in option D is not accurate as it is identified in the passage that Malory did write stories about Gareth, Tristan, and Isolde. Choices A, B, and C are all correctly identified as differences between the two authors based on the passage provided.
Christopher Columbus is often credited for discovering America. This is
incorrect. First, it is impossible to "discover" something where people already
live; however, Christopher Columbus did explore places in the New World
that were previously untouched by Europe, so the term “explorer†would be
more accurate. Another correction must be made, as well: Christopher
Columbus was not the first European explorer to reach the present day
Americas! Rather, it was Leif Erikson who first came to the New World and
contacted the natives, nearly five hundred years before Christopher
Columbus.
Leif Erikson, the son of Erik the Red (a famous Viking outlaw and explorer in
his own right), was born in either 970 or 980, depending on which historian you seek. His own family, though, did not raise Leif, which was a Viking
tradition. Instead, one of Erik's prisoners taught Leif reading and writing,
languages, sailing, and weaponry. At age 12, Leif was considered a man and
returned to his family. He killed a man during a dispute shortly after his
return, and the council banished the Erikson clan to Greenland.
In 999, Leif left Greenland and traveled to Norway where he would serve as a
guard to King Olaf Tryggvason. It was there that he became a convert to
Christianity. Leif later tried to return home with the intention of taking
supplies and spreading Christianity to Greenland, however his ship was blown
off course and he arrived in a strange new land: present day Newfoundland,
Canada.
When he finally returned to his adopted homeland Greenland, Leif consulted
with a merchant who had also seen the shores of this previously unknown
land we now know as Canada. The son of the legendary Viking explorer then
gathered a crew of 35 men and set sail. Leif became the first European to
touch foot in the New World as he explored present-day Baffin Island and
Labrador, Canada. His crew called the land Vinland since it was plentiful with
grapes.
During their time in present-day Newfoundland, Leif's expedition made
contact with the natives whom they referred to as Skraelings (which translates
to "wretched ones" in Norse). There are several secondhand accounts of their
meetings. Some contemporaries described trade between the peoples. Other
accounts describe clashes where the Skraelings defeated the Viking explorers
with long spears, while still others claim the Vikings dominated the natives.
Regardless of the circumstances, it seems that the Vikings made contact of
some kind. This happened around 1000, nearly five hundred years before
Columbus famously sailed the ocean blue.
Eventually, in 1003, Leif set sail for home and arrived at Greenland with a
ship full of timber.
In 1020, seventeen years later, the legendary Viking died. Many believe that
Leif Erikson should receive more credit for his contributions in exploring the
New World.
Which of the following battles occurred first?
- A. Cold Harbor
- B. Chancellorsville
- C. Atlanta
- D. Shiloh
Correct Answer: D
Rationale: Shiloh occurred earlier than the other battles listed. Shiloh took place in April 1862 during the American Civil War, making it the earliest battle among the options provided. Cold Harbor occurred in June 1864, Chancellorsville in May 1863, and Atlanta in July-September 1864. Therefore, Shiloh is the correct answer.
Choice A (Cold Harbor) is incorrect because it happened after Shiloh. Choice B (Chancellorsville) is incorrect because it occurred after Shiloh. Choice C (Atlanta) is also incorrect as it took place after Shiloh.
Tips for Eating Calcium Rich Foods Diary: Beverage - Include milk as a beverage at meals. * Consider choosing fat-free or low-fat milk. - Whole milk: consider a gradual shift to fat-free milk to lower saturated fat and calories. Start with reduced fat (2%), then low-fat (1%), and finally fat-free (skim). - Cappuccinos or lattes: ask for them with fat-free (skim) milk. Diary: Meals - Oatmeal and hot cereals: Try adding fat-free or low-fat milk instead of water - Use fat-free or low-fat milk when making condensed cream soups (e.g., cream of tomato) - Shredded low-fat cheese with casseroles, soups, stew, or vegetables - Fat-free or low-fat yogurt with a baked person Diary: Snack - Have fat-free or low-fat yogurt as a snack. * Make a dip for fruits or vegetable from yogurt. * Make fruit-yogurt smoothes in the blender. Diary: Dessert - Chocolate or butterscotch pudding with fat-free or low-fat milk. - Cut-up fruit with flavored yogurt for a quick dessert. Non-Diary Products: - Lactose Intolerance * Lactose-free alternatives within the milk group (e.g., cheese, yogurt, or lactose-free milk) * Consume the enzyme lactose before consuming milk products. - Personal choice to avoid diary: * Calcium fortified juices, cereals, breads, and soy or rice beverages * Canned fish (sardines, salmon with bones) soybeans and other soy products, some other dried beans, and some leafy greens.
What information should the author include to help clarify information in the passage?
- A. The fat content of yogurt.
- B. How much calcium is in fortified juice.
- C. Which leafy greens contain calcium.
- D. The definition of lactose intolerance.
Correct Answer: D
Rationale: The author should include information on the definition of lactose intolerance to help readers understand the need for lactose-free alternatives within the milk group. This clarification would provide context for why lactose-free options are recommended and help individuals make informed choices based on their dietary needs. Choices A, B, and C, although related to the topic of calcium-rich foods, do not directly address the issue of lactose intolerance and its implications for choosing suitable dairy alternatives.
The mother sun-fish, having now built or provided her "hatchery,"
deposits her spawn within the circular inclosure, and mounts guard at the
entrance until the fry are hatched out and are sufficiently large to take
charge of themselves.
What is the purpose of this passage?
- A. To describe the sun-fish's reproductive habits.
- B. To explain the ecosystem of the sun-fish.
- C. To persuade readers to protect aquatic ecosystems.
- D. To discuss the mating habits of sun-fish.
Correct Answer: A
Rationale: The correct answer is A. The passage describes the reproductive habits of the sun-fish, focusing on how the mother sun-fish provides and guards her spawn until they are ready to take care of themselves. Choice B is incorrect as the passage does not delve into the broader ecosystem of the sun-fish. Choice C is incorrect as there is no persuasive element in the passage about protecting aquatic ecosystems. Choice D is incorrect as the passage does not discuss the mating habits of sun-fish but rather the care provided by the mother sun-fish.
George Washington emerged out of the American Revolution as an unlikely
champion of liberty. On June 14, 1775, the Second Continental Congress
created the Continental Army, and John Adams, serving in the Congress,
nominated Washington to be its first commander. Washington fought under
the British during the French and Indian War, and his experience and prestige
proved instrumental to the American war effort. Washington provided
invaluable leadership, training, and strategy during the Revolutionary War. He
emerged from the war as the embodiment of liberty and freedom from
tyranny.
After vanquishing the heavily favored British forces, Washington could have
pronounced himself as the autocratic leader of the former colonies without
any opposition, but he famously refused and returned to his Mount Vernon
plantation. His restraint proved his commitment to the fledgling state's
republicanism. Washington was later unanimously elected as the first
American president. But it is Washington's farewell address that cemented his
legacy as a visionary worthy of study.
In 1796, President Washington issued his farewell address by public letter.
Washington enlisted his good friend, Alexander Hamilton, in drafting his
most famous address. The letter expressed Washington's faith in the
Constitution and rule of law. He encouraged his fellow Americans to put aside
partisan differences and establish a national union. Washington warned
Americans against meddling in foreign affairs and entering military alliances.
Additionally, he stated his opposition to national political parties, which he
considered partisan and counterproductive.
Americans would be wise to remember Washington's farewell, especially
during presidential elections when politics hits a fever pitch. They might want
to question the political institutions that were not planned by the Founding Fathers, such as the nomination process and political parties themselves.
What is one point on which the scientist and politician agree?
- A. Burning fossil fuels causes global temperatures to rise.
- B. Global temperatures are increasing.
- C. Countries must revisit their energy policies before it's too late.
- D. Earth's climate naturally goes through warming and cooling periods.
Correct Answer: B
Rationale: The correct answer is B: 'Global temperatures are increasing.' The scientist and politician both agree on this point based on the context provided. Choice A is incorrect because while it might be a common belief among scientists, the politician's agreement is not explicitly mentioned. Choice C is incorrect as it suggests a course of action rather than a point of agreement. Choice D is incorrect as it contradicts the consensus that global temperatures are currently increasing due to human activities, not just natural climate cycles.
