1. What is the author’s likely purpose in writing this passage about Queen Victoria?

• A. To persuade the reader to appreciate the accomplishments of Queen Victoria, especially when placed against the failures of her forebears.
• B. To introduce the historical impact of the Victorian Era by introducing to readers the queen who gave that era its name.
• C. To explain how small events in history placed an unlikely princess in line to become the queen of England.
• D. To indicate the role that King George III’s many sons played in changing the history of England.

Correct answer: C

Rationale: The correct answer is C. The author's purpose in writing this passage is to explain how small events in history led to an unlikely princess, Princess Alexandrina Victoria, becoming the queen of England. The passage discusses the family background of Queen Victoria and how a series of events, including the lack of legitimate heirs from King George III's sons, ultimately paved the way for her ascension to the throne. Choice A is incorrect because the passage is more focused on presenting historical events rather than persuading readers to appreciate Queen Victoria's accomplishments. Choice B is also incorrect as the passage does mention the Victorian Era but is primarily centered around Queen Victoria's personal journey to the throne. Choice D is incorrect as the passage does briefly mention King George III's sons, but it does not primarily focus on their role in changing the history of England.

2. Which of the following quantities do catalysts alter to control the rate of a chemical reaction?

• A. Substrate energy
• B. Activation energy
• C. Inhibitor energy
• D. Promoter energy

Correct answer: B

Rationale: The correct answer is B: Activation energy. Catalysts function by reducing the activation energy needed for a chemical reaction to proceed. By lowering the activation energy, catalysts facilitate the reaction without being consumed themselves. Substrate energy, inhibitors, and promoters are not directly altered by catalysts in the same way activation energy is. Substrate energy refers to the energy of the reactants, which is not altered by catalysts. Inhibitors increase the activation energy required for a reaction, while promoters enhance the effectiveness of a catalyst but do not represent a quantity altered by catalysts.

3. What is an electrically charged atom called?

• A. Ion
• B. Isotope
• C. Molecule
• D. Compound

Correct answer: A

Rationale: An ion is an atom that has gained or lost electrons, resulting in a positive or negative charge, making it electrically charged. This term specifically refers to atoms with a net electrical charge. Isotopes are atoms of the same element with different numbers of neutrons, not electrically charged. Molecules are formed when atoms bond together, but they are not necessarily charged. Compounds are substances composed of different elements bonded together, but they may not be electrically charged.

4. Which of the following statements is true about the dependent variable?

• A. A factor that remains constant during the experiment
• B. A factor with data typically plotted on the x-axis
• C. A factor that is measured during an experiment
• D. A factor with data typically plotted on the y-axis

Correct answer: C

Rationale: The correct answer is C. The dependent variable is the factor that is being measured or observed in an experiment. It is the outcome that is affected by changes in the independent variable. In graphical representations, the dependent variable is usually plotted on the y-axis, not the x-axis. Choice A is incorrect because a factor that remains constant is referred to as a constant, not a dependent variable. Choice B is incorrect as the independent variable's data is typically plotted on the x-axis. Choice D is incorrect because the dependent variable's data is usually plotted on the y-axis. Therefore, choice C accurately describes the dependent variable.

5. Solve |x| = 10.

• A. -10, 10
• B. -11, 11
• C. -12, 12
• D. -13, 13

Correct answer: A

Rationale: The absolute value of x is equal to 10 when x is either -10 or 10. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not satisfy the equation |x| = 10. For choice B, -11 and 11 do not satisfy the condition. Choices C and D also do not provide solutions that meet the equation's requirement.
