1. Which operation should be completed first in the expression 8 + 5 * 3?

• A. Multiplication
• B. Addition
• C. Division
• D. Subtraction

Correct answer: A

Rationale: The correct answer is 'Multiplication.' In the expression 8 + 5 * 3, according to the order of operations (PEMDAS), multiplication should be done before addition. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Therefore, the multiplication operation should be completed first, making 5 * 3 equal to 15, and then the addition operation should be conducted to get the final result of 8 + 15, which equals 23. Choices B, C, and D are incorrect because in this expression, multiplication takes precedence over addition, division, and subtraction according to the order of operations.

2. Which of the statements reflect information that one could reasonably infer based on the author's tone?

• A. The author's tone is persuasive and attempts to call the audience to action.
• B. The author's tone is passionate due to excitement over the subject and personal narrative.
• C. The author's tone is informative and exhibits interest in the subject of the study.
• D. The author's tone is somber, depicting some anger at the state of insect larvae.

Correct answer: A

Rationale: The statement 'The author's tone is persuasive and attempts to call the audience to action' reflects information that one could reasonably infer based on the author's tone. The use of persuasive language and an attempt to call the audience to action suggests that the author is trying to convince or motivate the readers to take a specific course of action. This inference is based on the author's choice of words and the overall tone of the text. Choice B is incorrect as it introduces the idea of excitement and personal narrative, which are not clearly indicated in the author's tone. Choice C is incorrect as although the author may be informative, the focus is on persuasive language rather than merely providing information. Choice D is incorrect as it introduces emotions like anger and somberness, which are not explicitly conveyed in the author's tone.

3. 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.

4. The Black Panther Party (BPP) was another activist group that formed around the same time as and was similar in function to the NAACP. What revision best improves this sentence?

• A. NO CHANGE
• B. was another activist group that
• C. had a lot of members that
• D. was another school that

Correct answer: B

Rationale: Describing the BPP as 'another activist group' provides clarity and relevance. Choice B correctly identifies the Black Panther Party as an activist group, aligning with its historical context and function. Choices C and D introduce irrelevant or inaccurate information, making them incorrect. Choice A, 'NO CHANGE,' leaves the sentence vague and does not provide the necessary clarification about the nature of the Black Panther Party.

5. A patient's body is not properly filtering blood. Which of the following body parts is most likely malfunctioning?

• A. Medulla
• B. Heart
• C. Nephrons
• D. Renal cortex

Correct answer: C

Rationale: Nephrons are the functional units of the kidneys responsible for filtering blood and removing waste products to form urine. If a patient's body is not properly filtering blood, it is most likely due to dysfunction or impairment in the nephrons of the kidneys. The heart is responsible for pumping blood, not filtering it, making choice B incorrect. The medulla and renal cortex are specific parts of the kidney but do not directly perform the filtration function carried out by the nephrons, making choices A and D incorrect.
