1. What is insulin, where is it produced, and what is its function?

• A. Produced in the liver, regulates fat storage
• B. Produced in the pancreas, regulates blood sugar
• C. Produced in the stomach, aids in digestion
• D. Produced in the kidneys, controls hydration

Correct answer: B

Rationale: Insulin is a hormone produced in the pancreas. Its primary function is to regulate blood sugar levels by facilitating the uptake of glucose by cells for energy. The other choices are incorrect as insulin is not produced in the liver (Choice A), stomach (Choice C), or kidneys (Choice D), and its function is not related to fat storage, digestion, or hydration. Therefore, the correct answer is B.

2. Based on a favorable performance review at work, Matt receives a 3/20 increase in his hourly wage. If his original hourly wage is represented by w, which of the following represents his new wage?

• A. 0.15w
• B. 0.85w
• C. 1.12w
• D. 1.15w

Correct answer: D

Rationale: To calculate Matt's new wage after a 3/20 increase, we need to add this percentage increase to his original wage. The increase in decimal form is 3/20 = 0.15. Therefore, the new wage is w + w(0.15) = w(1 + 0.15) = 1.15w. This means the correct answer is D. Choices A, B, and C are incorrect because they do not account for the full 3/20 increase in the wage. Choice A (0.15w) represents only the increase percentage, not the total new wage. Choice B (0.85w) and Choice C (1.12w) do not accurately calculate the new wage after the increase, leading to incorrect representations of the final wage.

3. Which of the following spellings is correct?

• A. Dependant
• B. Dependent
• C. Dependunt
• D. Dependent

Correct answer: D

Rationale: The correct spelling is 'dependent,' meaning someone who relies on another for support. Choice A, 'Dependant,' is a common misspelling. Choice B, 'Dependint,' is incorrect. Choice C, 'Dependunt,' is also incorrect. Therefore, the correct answer is 'Dependent.'

4. Lymph nodes, found along lymphatic vessels, are important for:

• A. Storing blood
• B. Producing antibodies
• C. Filtering lymph and trapping harmful substances
• D. All of the above

Correct answer: C

Rationale: Lymph nodes are essential for filtering lymph and trapping harmful substances. They are a vital part of the immune system as they remove pathogens and harmful substances from the lymph before it returns to the bloodstream. Lymph nodes do not store blood or produce antibodies, making choice C the correct answer. Choice A is incorrect because lymph nodes do not store blood; they primarily filter lymph. Choice B is incorrect as lymph nodes do not produce antibodies; that function is mainly carried out by specialized cells within the immune system. Choice D is incorrect as lymph nodes do not perform all the functions listed, making it an incorrect answer.

5. Why does the author say it is important to buy locally grown food?

• A. Buying locally grown food supports people in your community.
• B. Locally grown food travels the least distance to reach you and therefore uses fewer resources.
• C. Locally grown food uses less packaging.
• D. Locally grown food is healthier for you because it has been exposed to fewer pesticides.

Correct answer: B

Rationale: The author stresses the significance of buying locally grown food due to its minimal travel distance, which results in reduced resource utilization. This aligns with the passage's primary environmental theme of conserving resources for the future. Choice A is incorrect because although buying locally grown food can support the community, the main focus in the passage is on resource conservation. Choice C is incorrect as the passage emphasizes the importance of packaging but does not specifically mention that locally grown food uses less packaging. Choice D is incorrect as the health aspect related to fewer pesticides is not discussed in the passage regarding the importance of buying locally grown food.
