1. Which factor does not affect the reaction rate of a chemical reaction?

• A. Temperature
• B. Surface area
• C. Concentration of reactants
• D. Color of the reactants

Correct answer: D

Rationale: The color of reactants is not a factor that affects the rate of a chemical reaction. Temperature, surface area, and concentration of reactants are known factors that influence the reaction rate. Temperature plays a significant role in altering the reaction rate by affecting the kinetic energy of molecules. Surface area impacts the rate by providing more area for collisions to occur. Concentration affects the frequency of effective collisions. On the other hand, the color of reactants is a physical property that does not directly affect the speed of a chemical reaction.

2. Which word is not spelled correctly in the context of the sentence? Unfortunately, her absences were becoming a regular occurrence.

• A. Unfortunately
• B. absences
• C. regular
• D. occurrence

Correct answer: D

Rationale: The word 'ocurrence' is spelled incorrectly. The correct spelling is 'occurrence.' In this context, 'occurrence' refers to something happening or taking place, making it the appropriate term for the sentence. Choice A, 'Unfortunately,' is spelled correctly. Choice B, 'absences,' is spelled correctly. Choice C, 'regular,' is spelled correctly. Therefore, the incorrect spelling in the sentence is 'occurrence,' making it the right answer.

3. Select the word that means 'a violent seizure.'

• A. revelation
• B. nutrient
• C. contraption
• D. paroxysm

Correct answer: D

Rationale: 'Paroxysm' is the correct answer as it refers to a sudden, violent seizure or outburst. The other choices are incorrect because 'revelation' means a surprising and previously unknown fact, 'nutrient' refers to a substance that provides nourishment, and 'contraption' means a machine or device that is strange or unnecessarily complicated.

4. What does Labile mean?

• A. Stable
• B. Changing rapidly and often
• C. Unchanging
• D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

5. Which might be a good title for this passage?

• A. “Everyone Should Run Barefoot”
• B. “How to Prevent Running Injuries”
• C. “Modern Road Surfaces Versus Barefoot Running”
• D. “The Debate over Barefoot Running”

Correct answer: D

Rationale: The title "The Debate over Barefoot Running" encapsulates the central theme of the passage, which explores both the advantages and disadvantages of barefoot running. It effectively summarizes the discussions around differing opinions and the lack of consensus on this topic. Other titles do not accurately reflect the primary focus of the essay, making D the most suitable choice.
