1. Identify the article in the following sentence: The delicious cake was enjoyed by everyone at the party.

• A. cake
• B. was
• C. the
• D. enjoyed

Correct answer: C

Rationale: The correct answer is 'C - the.' Articles ('a,' 'an,' and 'the') indicate specificity of a noun. In this sentence, 'the' specifies that there is one particular cake being discussed. Choice A ('cake') is incorrect as it is the noun being modified by the article. Choice B ('was') is a verb and not an article. Choice D ('enjoyed') is also a verb and not an article.

2. Which of the following is a strong acid?

• A. Acetic acid (CH₃COOH)
• B. Hydrochloric acid (HCl)
• C. Citric acid
• D. Carbonic acid (Hâ‚‚CO₃)

Correct answer: B

Rationale: Hydrochloric acid (HCl) is a strong acid because it completely ionizes in water to produce hydrogen ions, leading to a high concentration of H⁺ ions in solution. This characteristic makes it a strong acid. Acetic acid (CH₃COOH), citric acid, and carbonic acid (H₂CO₃) are weak acids as they only partially ionize in water, resulting in a lower concentration of H⁺ ions compared to strong acids. Therefore, hydrochloric acid is the correct choice as a strong acid.

3. Which level of protein structure is defined by the folds and coils of the protein's polypeptide backbone?

• A. Primary
• B. Secondary
• C. Tertiary
• D. Quaternary

Correct answer: B

Rationale: The correct answer is B: Secondary. The secondary structure of a protein is defined by the folding and coiling of the polypeptide backbone into structures like alpha helices and beta sheets. Secondary structure primarily involves interactions such as hydrogen bonding within the backbone. This level of protein structure is distinct from primary structure (A) which refers to the linear sequence of amino acids, tertiary structure (C) which involves the overall 3D arrangement of a single polypeptide chain, and quaternary structure (D) which pertains to the interaction between multiple polypeptide chains in a protein complex.

4. What is the formula to convert Celsius to Fahrenheit?

• A. (C × 9/5) + 32
• B. (C × 5/9) + 32
• C. (F × 9/5) - 32
• D. (F × 5/9) - 32

Correct answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is (C × 9/5) + 32. This formula involves multiplying the Celsius temperature by 9/5 and then adding 32 to get the Fahrenheit temperature. Choice B is incorrect as it suggests dividing by 5/9 instead of multiplying by 9/5. Choices C and D are both incorrect because they involve using the Fahrenheit temperature in the calculation, which is not the correct method for converting Celsius to Fahrenheit.

5. While researching Chomsky's Jewish heritage, Teddy wants to research traditional Judaism. Which section of the library would most likely contain the most relevant information?

• A. 100
• B. 200
• C. 300
• D. 900

Correct answer: B

Rationale: The correct answer is B: '200.' According to the Dewey Decimal System, religion falls under section 200. Traditional Judaism research aligns with religious studies, making section 200 the most suitable for finding relevant information. Choices A, C, and D do not directly relate to religious topics and are therefore less likely to contain information on traditional Judaism.
