1. Which of the following statements best summarizes the central purpose of this text?

• A. Gulliver details his experiences and interactions with the natives of the new land.
• B. Gulliver observes the unique customs and traditions of the society he encounters.
• C. Gulliver becomes acquainted with the people and practices of his new surroundings.
• D. Gulliver reflects on the cultural differences between his homeland and the new land.

Correct answer: C

Rationale: The correct answer is C because the text describes how Gulliver becomes familiar with the customs and practices of the new society he finds himself in. He interacts with the natives, learns their language, and participates in their shows, indicating his growing understanding and acceptance of the new culture. Choice A is incorrect because the text goes beyond detailing his experiences to focus on his growing familiarity with the society. Choice B is incorrect because Gulliver not only observes but actively engages with the customs. Choice D is incorrect as the focus is on Gulliver's adaptation rather than reflecting on cultural differences.

2. To begin making her soup, Jennifer added four containers of chicken broth with 1 liter of water into the pot. Each container of chicken broth contains 410 milliliters. How much liquid is in the pot?

• A. 1.64 liters
• B. 2.64 liters
• C. 5.44 liters
• D. 6.12 liters

Correct answer: B

Rationale: Each container of chicken broth contains 410 milliliters. Jennifer added four containers, which totals 4 * 410 = 1640 milliliters of chicken broth. She then added 1 liter of water, equivalent to 1000 milliliters. Combining all the liquids, we get 1640 + 1000 = 2640 milliliters, which equals 2.64 liters. Choice A is incorrect because it miscalculates the total liquid volume. Choice C is incorrect as it greatly overestimates the liquid amount. Choice D is incorrect as it also overestimates the liquid content in the pot.

3. Which of the following is an opinion, rather than a historical fact, expressed by the author?

• A. Leif Erikson was definitely the son of Erik the Red.
• B. Leif Erikson's crew called the land Vinland.
• C. Leif Erikson deserves more credit for his accomplishments.
• D. Leif Erikson explored the Americas nearly five hundred years before Columbus.

Correct answer: C

Rationale: The statement 'Leif Erikson deserves more credit for his accomplishments' is an opinion rather than a historical fact. Historical facts can be verified through evidence and documentation, while opinions are subjective viewpoints. Choices A, B, and D provide historical facts about Leif Erikson's lineage, the name given to the land he discovered, and his exploration, respectively, which can be supported by historical records and research.

4. What property of matter explains why ice floats on water?

• A. Viscosity
• B. Density
• C. Buoyancy
• D. Surface tension

Correct answer: C

Rationale: The correct answer is C, buoyancy. Ice floats on water due to buoyancy, a property of matter. When water freezes into ice, it becomes less dense than liquid water, causing it to float. This phenomenon occurs because the molecules in ice are more spread out compared to liquid water, resulting in ice being less dense and able to float on the surface. Choice A, viscosity, is incorrect because viscosity refers to a fluid's resistance to flow, not its ability to float. Choice B, density, is incorrect because while ice being less dense than water is the reason it floats, this choice does not explain the specific property that causes this phenomenon. Choice D, surface tension, is incorrect as it pertains to the cohesive forces between molecules at the surface of a liquid, not the reason why ice floats on water.

5. What are the differences between RNA and DNA?

• A. Both have the same structure and function.
• B. RNA is single-stranded, while DNA is double-stranded.
• C. RNA contains ribose sugar, while DNA contains deoxyribose sugar.
• D. RNA has adenine and guanine, while DNA has thymine and cytosine.

Correct answer: B

Rationale: A) This statement is incorrect. RNA and DNA have different structures and functions. RNA is involved in protein synthesis and other cellular processes, while DNA stores genetic information. B) This statement is correct. RNA is typically single-stranded, while DNA is double-stranded, forming a double helix structure. C) This statement is correct. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. D) This statement is incorrect. RNA contains adenine, guanine, cytosine, and uracil, while DNA contains adenine, guanine, cytosine, and thymine. Choice B is the correct answer as it accurately describes one of the key differences between RNA and DNA, emphasizing their structural disparity in terms of single-strandedness for RNA and double-strandedness for DNA. Choices A, C, and D contain inaccuracies regarding the structural and compositional distinctions between RNA and DNA, making them incorrect choices.
