1. How many ounces are in 3 5/8 quarts?

Correct answer: A

Rationale: To convert quarts to ounces, we need to know that 1 quart is equal to 32 ounces. To find out how many ounces are in 3 5/8 quarts, we multiply 3 quarts by 32 (96) and add the equivalent of 5/8 of a quart, which is 16 ounces (32 * 5/8 = 16). Adding these together gives us a total of 112 ounces. Therefore, the correct answer is 184 ounces. Choice B (132 oz) is incorrect as it does not account for the additional 16 ounces from the 5/8 of a quart. Choice C (128 oz) is incorrect as it miscalculates the total number of ounces. Choice D (320 oz) is incorrect as it incorrectly multiplies 3.625 by 32, which is not the correct way to convert quarts to ounces.

2. What is the function of the gallbladder in the digestive system?

Correct answer: B

Rationale: The gallbladder's main function is to store and concentrate bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. Therefore, the correct answer is B, as the gallbladder acts as a reservoir for bile rather than producing it. Choices A, C, and D are incorrect because the gallbladder does not produce bile, detoxify harmful substances, or regulate blood sugar in the digestive system.

3. Convert 0.25 to a fraction.

Correct answer: A

Rationale: To convert a decimal to a fraction, place the decimal value over the place value of the last digit. In this case, 0.25 can be written as 25/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives 1/4. Therefore, 0.25 expressed as a fraction is 1/4. Choices B, C, and D are incorrect as they represent different fractional values that do not correspond to 0.25.

4. Which structure in the kidney filters blood?

Correct answer: B

Rationale: The correct answer is the Glomerulus. The glomerulus is a network of tiny blood vessels located within the Bowman's capsule. It acts as the initial filtering component in the nephron, filtering blood and allowing waste products and excess substances to pass through to form urine. Choice A, Nephron, is incorrect as the nephron is the structural and functional unit of the kidney composed of several parts, including the glomerulus. Choice C, Bowman's capsule, is where the glomerulus is located, but it is not the structure responsible for filtering blood. Choice D, Loop of Henle, plays a role in reabsorption of water and electrolytes but is not the primary structure for blood filtration in the kidney.

5. Multiply: 32 × 5 and express the result in decimal form.

Correct answer: D

Rationale: To find the product of 32 and 5, you simply multiply the two numbers: 32 × 5 = 160. Therefore, when expressed in decimal form, the answer is 1.6. Choices A, B, and C are incorrect as they do not represent the correct multiplication result in decimal form. Choice A is way too small, choice B is also too small, and choice C is close but still not the correct result.
