Which of the following is an example of a secondary source that would be used in a documentary about World War I?
- A. an essay by a historian about the lasting effects of the war
- B. photographs of military equipment used in the war
- C. a recorded interview with a veteran who fought for the US Army
- D. letters written by soldiers to their families
Correct Answer: A
Rationale: An essay by a historian about the lasting effects of the war is an example of a secondary source as it provides analysis and interpretation of primary sources like official documents, photographs, and letters. It offers a perspective that is based on research and not directly involved in the events, making it a valuable resource for understanding the historical context of World War I. Choice B, photographs of military equipment, is a primary source as it provides direct visual evidence from the time period. Choice C, a recorded interview with a veteran, is also a primary source as it offers firsthand accounts from someone directly involved in the events. Choice D, letters written by soldiers, are primary sources that offer insights into the personal experiences of individuals during the war.

Skin coloration and markings have an important role to play in the world of snakes. Those intricate diamonds, stripes, and swirls help the animals hide from predators, but perhaps most importantly (for us humans, anyway), the markings can also indicate whether the snake is venomous. While it might seem counterintuitive for a venomous snake to stand out in bright red or blue, that fancy costume tells any nearby predator that approaching him would be a bad idea.
If you see a flashy-looking snake in the woods, though, those markings don't necessarily mean it's venomous: some snakes have found a way to ward off predators without the actual venom. The scarlet kingsnake, for example, has very similar markings to the venomous coral snake with whom it frequently shares a habitat. However, the kingsnake is actually nonvenomous; it's merely pretending to be dangerous to eat. A predatory hawk or eagle, usually hunting from high in the sky, can't tell the difference between the two species, and so the kingsnake gets passed over and lives another day.
What is the author's primary purpose in writing this essay?
- A. To explain how the markings on a snake are related to its venomous nature.
- B. To teach readers the difference between coral snakes and kingsnakes.
- C. To illustrate why snakes are dangerous.
- D. To demonstrate how animals adapt to difficult environments.
Correct Answer: B
Rationale: The correct answer is B. The author's primary purpose in writing this essay is to teach readers the difference between coral snakes and kingsnakes. The essay discusses how skin coloration and markings help snakes hide from predators and indicate whether a snake is venomous. By comparing the physical characteristics and behaviors of coral snakes and kingsnakes, the author helps readers understand how to distinguish between the two species to avoid potential dangers. Choice A is incorrect because the essay focuses more on distinguishing between snake species rather than solely on the relationship between markings and venom. Choice C is incorrect as the essay does not aim to illustrate why snakes are dangerous but rather to educate about the differences between specific snake types. Choice D is incorrect as the essay does not discuss how animals survive in difficult environments, but instead focuses on snake markings and behaviors.
The greatest changes in sensory, motor, and perceptual development happen in the first two years of life. When babies are first born, most of their senses operate in a similar way to those of adults. For example, babies are able to hear before they are born; studies show that babies turn toward the sound of their mothers' voices just minutes after being born, indicating they recognize the mother's voice from their time in the womb.
The exception to this rule is vision. A baby's vision changes significantly in its first year of life; initially it has a range of vision of only 8 - 12 inches and no depth perception. As a result, infants rely primarily on hearing; vision does not become the dominant sense until around the age of 12 months. Babies also prefer faces to other objects. This preference, along with their limited vision range, means that their sight is initially focused on their caregiver.
Which of the following best describes the mode of the passage?
- A. expository
- B. narrative
- C. persuasive
- D. descriptive
Correct Answer: A
Rationale: The passage is expository as it provides factual information about the sensory, motor, and perceptual development in babies during the first two years of life. It explains how babies' senses develop, focusing on hearing and vision in their early stages. The passage presents these developmental milestones in a straightforward and informative manner, making it expository.
Choice B (narrative) is incorrect because the passage does not tell a story or present a sequence of events involving characters. Choice C (persuasive) is incorrect as there is no attempt to convince or persuade the reader of a particular viewpoint. Choice D (descriptive) is incorrect because the passage does not aim to create a vivid picture or impression using sensory details; instead, it focuses on providing clear information about sensory development in infants.

What is the best summary of this passage?
- A. Humans can use coloration and markings on snakes to determine whether they're venomous.
- B. Animals use coloration to hide from predators.
- C. The scarlet kingsnake and the coral snake have nearly identical markings.
- D. Venomous snakes often have bright markings, although nonvenomous snakes can also mimic those colors.
Correct Answer: A
Rationale: The best summary of the passage is that humans can use coloration and markings on snakes to determine whether they're venomous. The passage discusses how snake markings serve the purpose of warning predators and helping humans identify venomous snakes by their bright coloration. Choice B is incorrect because the passage focuses on how coloration helps snakes evade predators rather than hide from them. Choice C is incorrect as it only mentions two specific snakes with similar markings, which is a minor detail compared to the main point of identifying venomous snakes. Choice D is incorrect because it only partially reflects the passage, focusing solely on the relationship between markings and venom in snakes, missing the crucial aspect of human ability to discern venomous snakes based on their coloration.
After looking at five houses, Robert and I have decided to buy the one on
Forest Road. The first two homes we visited didn't have the space we need —the first had only one bathroom, and the second did not have a guest bedroom. The third house, on Pine Street, had enough space inside but didn't have a big enough yard for our three dogs. The fourth house we looked at, on Rice Avenue, was stunning but well above our price range. The last home, on Forest Road, wasn't in the neighborhood we wanted to live in. However, it had the right amount of space for the right price.
What is the author's conclusion about the house on Pine Street?
- A. The house did not have enough bedrooms.
- B. The house did not have a big enough yard.
- C. The house was not in the right neighborhood.
- D. The house was too expensive.
Correct Answer: D
Rationale: The author's conclusion about the house on Pine Street is that it was too expensive. This can be inferred from the description provided in the text, where it is mentioned that although the house had enough space inside, it didn't have a big enough yard for their dogs, and the cost of the house was well above their price range. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not align with the evidence from the text, which clearly points to the cost being the main issue with the house on Pine Street.
It had been a long morning for Julia. She'd been woken up early by the sound of lawn mowers outside her window, and despite her best efforts, had been unable to get back to sleep. So, she'd reluctantly got out of bed, showered, and prepared her morning cup of coffee. At least, she tried to anyway. In the kitchen she'd discovered she was out of regular coffee and had to settle for a decaffeinated cup instead.
Once on the road, her caffeine-free mug of coffee didn't help make traffic less annoying. In fact, it seemed to Julia like the other drivers were sluggish and surly as well—it took her an extra fifteen minutes to get to work. And when she arrived, all the parking spots were full.
By the time she'd finally found a spot in the overflow lot, she was thirty minutes late for work. She'd hoped her boss would be too busy to notice, but he'd already put a pile of paperwork on her desk with a note that simply said “Rewrite.†She wondered if she should point out to her boss that she hadn't been the one to write the reports in the first place, but decided against it.
When the fire alarm went off an hour later, Julia decided she'd had enough. She grabbed her purse and headed outside with her coworkers. While everyone else stood around waiting for the alarm to quiet, Julia determinedly walked to her car, fired up the engine, and set a course for home.
Which of the following statements based on the passage should be considered an opinion?
- A. Julia's boss asked her to help one of her coworkers with work.
- B. Julia was late to work due to traffic.
- C. It was irresponsible for Julia to leave work early.
- D. Julia was tired because she'd been woken up early.
Correct Answer: C
Rationale: The statement 'It was irresponsible for Julia to leave work early' is an opinion because it reflects a judgment or evaluation of Julia's actions, rather than stating a fact. The other statements (A, B, D) provide factual information about events that occurred in the passage. Option A states a fact about Julia being asked by her boss; option B explains the reason for Julia being late; option D provides a reason for Julia feeling tired. These are not opinions but rather statements of events or circumstances.
