1. When animals eat, insulin is released from the pancreas, stimulating glucose uptake by the liver. When glucose levels drop, the pancreas reduces insulin release. This is an example of which mechanism for maintaining homeostasis?

Correct answer: A

Rationale: This mechanism is an example of negative feedback. Negative feedback systems work to counteract changes in the body and maintain a stable internal environment (homeostasis). In this case, the release of insulin in response to high glucose levels is followed by a reduction in insulin release when glucose levels drop. This response helps regulate glucose levels and return them to a normal range, demonstrating the characteristic of negative feedback where the body's response opposes the initial stimulus to maintain equilibrium. Positive feedback would amplify the initial change rather than counteract it, so it is not the correct choice. Stress response and parasympathetic regulation are not directly involved in this glucose regulation process, making them incorrect choices.

2. Which of the following is a major factor influencing the distribution of organisms geographically?

Correct answer: D

Rationale: The distribution of organisms geographically is influenced by various factors. The availability of specific types of food sources is crucial as organisms need suitable food sources to survive and thrive in an area. Tolerance of organisms to different temperature ranges is also important, as temperature impacts where species can live. Organisms must withstand temperature conditions to survive. Competition for mates within the same species affects population sizes and dynamics in different areas. Therefore, all these factors collectively influence the distribution of organisms geographically. Choice D, 'All of the above,' is the correct answer because each of the factors mentioned (availability of food sources, tolerance to temperature ranges, and competition for mates) plays a significant role in determining the distribution of organisms in different geographical locations. Choices A, B, and C are incorrect because they each only represent one specific factor that influences distribution, whereas the correct answer encompasses all the major factors mentioned.

3. Which statement from the passage best supports the conclusion that taking notes and recording audio during an interview is a good practice for journalists?

Correct answer: D

Rationale: The statement about the dual-note method best supports the conclusion that taking notes and recording audio is a good practice. It highlights the advantage of having two resources - notes and audio recordings - which provide comprehensive coverage of the interview. Choice A simply mentions the use of a recording device but does not emphasize the benefits of combining it with note-taking. Choices B and C focus on the limitations or potential issues with using recording devices, which do not promote the practice as positively as Choice D.

4. A gift box has a length of 14 inches, a height of 8 inches, and a width of 6 inches. How many square inches of wrapping paper are needed to wrap the box?

Correct answer: C

Rationale: To find the surface area of a rectangular prism, you use the formula SA = 2lw + 2wh + 2hl, where l is the length, w is the width, and h is the height. Substituting the given dimensions, the calculation would be SA = 2(14)(6) + 2(6)(8) + 2(8)(14) = 168 + 96 + 224 = 488 square inches. Therefore, 488 square inches of wrapping paper are needed to wrap the box. Choice A (56), Choice B (244), and Choice D (672) are incorrect because they do not represent the correct surface area calculation for the given box dimensions.

5. An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she used?

Correct answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.
