1. What is the term for the process of breaking a large molecule into smaller fragments by applying heat?

• A. Polymerization
• B. Hydrogenation
• C. Isomerization
• D. Pyrolysis

Correct answer: D

Rationale: Pyrolysis is the process of breaking down large molecules into smaller fragments by applying heat. The other choices involve different chemical processes.

2. A decorative globe has a diameter of 25cm. What is its total surface area?

• A. 1570 sq cm
• B. 1963 sq cm
• C. 2513 sq cm
• D. 3142 sq cm

Correct answer: B

Rationale: Use the formula for surface area of a sphere: 4 * π * (radius)^2, where radius is half the diameter. Calculate the radius (12.5cm) and substitute: 4 * π * (12.5cm)^2 ≈ 1963 sq cm.

3. Which conjunction best joins the following sentence: "She loves animals, ____ she volunteers at the shelter."

• A. because
• B. therefore
• C. so
• D. and

Correct answer: D

Rationale: "And" simply adds information about her love for animals without implying cause or effect.

4. Aromatic compounds

• A. Contain a ring structure with alternating single and double bonds
• B. Readily undergo addition reactions
• C. Are easily broken down by water
• D. Do not contain any pi (Ï€) bonds

Correct answer: A

Rationale: The correct answer is A: 'Aromatic compounds contain a ring structure with alternating single and double bonds.' Aromatic compounds exhibit a special stability due to the delocalization of pi electrons within the ring, known as resonance. This resonance occurs because of the alternating single and double bonds in the ring structure, making them less reactive towards addition reactions compared to alkenes, which have only double bonds. This stability also makes aromatic compounds less likely to be easily broken down by water, as they are relatively inert in many chemical reactions. Therefore, aromatic compounds do contain pi (π) bonds due to the presence of the alternating single and double bonds in their ring structure.

5. Identify the incorrect usage of punctuation in the following sentence: "The children, eager to play, ran outside. It was a beautiful day."

• A. comma after "children"
• B. comma after "play"
• C. period after "outside"
• D. no errors

Correct answer: C

Rationale: The two sentences are independent clauses and should be separated by a semicolon or period, not a comma.

6. There are times when Katherine evaluates her staff as she makes her daily rounds. Which of

• A. The staff member is observed in natural setting.
• B. Incidental confrontation and collaboration is allowed.
• C. The evaluation is focused on objective data systematically.
• D. The evaluation may provide valid information for compilation of a formal report.

Correct answer: A

Rationale: The correct answer is A: 'The staff member is observed in a natural setting.' This option is the most appropriate because it aligns with the concept of naturalistic observation, where behavior is observed in its natural environment without interference or manipulation. In this scenario, Katherine is observing her staff during her daily rounds without any alterations to their behavior or environment. This allows for a more authentic and unbiased assessment of their performance. Options B, C, and D are not as relevant to the concept of naturalistic observation and do not accurately describe the situation presented in the question.
