1. To which section of the library should Jorgen go to learn more about the letters of the Greek alphabet and the meaning of the word 'beta'?

• A. 200
• B. 400
• C. 700
• D. 900

Correct answer: B

Rationale: Jorgen should go to section 400 in the library to learn more about the Greek alphabet and the meaning of the word 'beta'. Section 400 is dedicated to languages, which makes it the most appropriate place for this specific inquiry. Choices A, C, and D are incorrect because section 200 is dedicated to religion, section 700 covers arts and recreation, and section 900 focuses on history, geography, and biography, none of which would provide information about the Greek alphabet or the word 'beta'.

2. What is the molarity of a solution made by dissolving 4.0 grams of NaCl into enough water to make 120 mL of solution? The atomic mass of Na is 23.0 g/mol, and Cl is 35.5 g/mol.

• A. 0.34 M
• B. 0.57 M
• C. 0.034 M
• D. 0.057 M

Correct answer: B

Rationale: To find the molarity, first calculate the moles of NaCl. Moles of NaCl = 4.0 g / (23.0 g/mol + 35.5 g/mol) = 0.068 mol. Next, use the formula for molarity: Molarity = moles of solute / liters of solution. Molarity = 0.068 mol / 0.120 L = 0.57 M. Therefore, the molarity of the solution is 0.57 M. Choice A, 0.34 M, is incorrect as it does not match the calculated molarity. Choice C, 0.034 M, is incorrect as it is a decimal point off from the correct molarity. Choice D, 0.057 M, is incorrect as it does not match the calculated molarity of 0.57 M.

3. Which of the following is a concise summary of the passage?

• A. Babies focus on their caregivers' faces due to their lack of depth perception until 12 months.
• B. Babies recognize their mothers' voices at birth, relying primarily on hearing initially.
• C. Babies have adult-like senses except for vision, which fully develops by 12 months.
• D. Babies' senses undergo significant changes in their first year of life.

Correct answer: D

Rationale: Option D is the most concise summary of the passage as it encapsulates the main idea that the passage focuses on the changes in babies' senses during their first year of life. The passage explains how babies are born with sensory abilities similar to adults but highlights the significant changes that occur during the first year, particularly in vision development. While the other options touch on specific aspects mentioned in the passage, they do not capture the overall essence of the passage, which emphasizes the dynamic and transformative nature of babies' sensory experiences in their first year.

4. What is the name for the smallest amount of an element that can exist independently and retain its chemical properties?

• A. Atom
• B. Molecule
• C. Compound
• D. Mixture

Correct answer: A

Rationale: The correct answer is 'Atom.' An atom is the fundamental unit of an element that can exist independently and retain its unique chemical properties. It consists of a nucleus containing protons and neutrons, surrounded by electrons. Choice B, 'Molecule,' is incorrect because a molecule is a combination of two or more atoms bonded together. Choice C, 'Compound,' is incorrect as a compound is a substance formed by the chemical combination of two or more different elements. Choice D, 'Mixture,' is incorrect since a mixture is a blend of two or more substances physically combined, but the individual components retain their properties.

5. Which of the following is NOT an example of a phrase that might be found within the transition sentence of a paragraph?

• A. In the same way
• B. Research proves that
• C. Another reason for this is
• D. As a result

Correct answer: B

Rationale: In academic writing, transition sentences are used to connect ideas within a paragraph. Phrases like 'In the same way,' 'Another reason for this is,' and 'As a result' are commonly used to transition between different points. However, 'Research proves that' is more indicative of a factual statement rather than a transitional phrase. It presents information rather than smoothly transitioning between ideas, making it the correct choice as it does not fit the typical structure and function of a transition sentence.
