- B. We chose this particular restaurant because of its outdoor seating.
- C. Finally, we were able to settle in to enjoy the movie.

Correct Answer: C
Rationale: The sentence 'Finally, we were able to settle in to enjoy the movie.' indicates the completion or conclusion of a sequence of events. The word 'finally' signals that something has been achieved or reached at the end of a series of actions or events. Choices A, B, and D do not indicate the end of a sequence but rather express different points within a series of events or actions.

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 senses do babies primarily rely on during their early development?
- A. vision
- B. hearing
- C. touch
- D. smell
Correct Answer: C
Rationale: Babies primarily rely on the sense of touch during their early development. Their sense of touch is one of the first senses to develop, allowing them to explore and understand the world around them. Touch helps babies bond with caregivers, provides comfort, and facilitates learning about different textures and sensations. While vision, hearing, and smell are also important, touch plays a crucial role in infants' early development and communication. The provided extract explains that babies initially rely on hearing and later on vision, with touch being essential for early bonding and exploration, making it the primary sense in infancy.
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 purpose of the passage?
- A. to inform
- B. to entertain
- C. to describe
- D. to persuade
Correct Answer: A
Rationale: The main purpose of this passage is to inform readers about the role of skin coloration and markings in snakes. It explains how these markings help snakes hide from predators and how they can also indicate venomousness. The passage also provides examples such as the scarlet kingsnake to illustrate how some nonvenomous snakes mimic the appearance of venomous snakes for protection. This informative content aims to educate readers about the survival strategies of snakes, rather than entertain, describe, or persuade them.
How to Plant Potatoes
Before Planting
Plant potatoes no later than 2 weeks after the last spring freeze.
Cut potatoes into pieces 1 to 2 days before planting.
Loosen soil using a tiller or hand trowel.
Mix fertilizer or compost into loosened soil.
Planting
Dig a 4-inch-deep trench and place potatoes 1 foot apart.
Cover potatoes loosely with soil.
After Planting
Water immediately after planting, and then regularly afterward to keep soil moist.
After 6 weeks, mound soil around the base of the plant to ensure roots stay covered.
What should be done after the soil has been loosened with a tiller or trowel?
- A. Mix fertilizer or compost into loosened soil.
- B. Dig a 4-inch-deep trench.
- C. Cut potatoes into pieces.
- D. Mound soil around the base of the plant.
Correct Answer: A
Rationale: After the soil has been loosened with a tiller or trowel, the next step should be to mix fertilizer or compost into the loosened soil. This action is crucial as it provides essential nutrients for plant growth, improves soil fertility, and promotes healthy plant development. Digging a trench, cutting potatoes, or mounding soil around the base of the plant are not tasks typically performed immediately after loosening the soil. Therefore, option A is the correct choice as it aligns with the standard practice of enhancing soil quality before planting.

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.

What can the reader conclude from the passage above?
- A. The kingsnake is dangerous to humans.
- B. The coral snake and the kingsnake are both hunted by the same predators.
- C. It's safe to handle snakes in the woods because you can easily tell whether they're poisonous.
- D. The kingsnake changes its markings when hawks or eagles are close by.
Correct Answer: B
Rationale: The correct answer is B. The passage explains that the kingsnake mimics the venomous coral snake's markings to deter predators, particularly hawks and eagles, which cannot differentiate between the two species. This implies that both the coral snake and the kingsnake face similar threats from predators in their shared habitat. Choice A is incorrect because the passage clearly states that the kingsnake is nonvenomous, so it is not dangerous to humans. Choice C is incorrect as the passage highlights that not all snakes with flashy markings are venomous, emphasizing the need for caution. Choice D is incorrect as there is no mention of the kingsnake changing its markings in response to the presence of hawks or eagles in the passage.
