1. What is the best definition of economy as it is used in this passage?

• A. Exchange of money, goods, and services
• B. Delegation of household affairs
• C. Efficient money management
• D. Less expensive

Correct answer: C

Rationale: The correct definition of 'economy' in this passage is 'efficient money management.' The passage emphasizes the importance of expending less than what is earned, which is a key aspect of efficient money management. Choice A, 'Exchange of money, goods, and services,' is too broad and does not capture the essence of the passage. Choice B, 'Delegation of household affairs,' is not directly related to the context of the passage. Choice D, 'Less expensive,' does not encompass the concept of managing money efficiently as discussed in the passage.

2. A bucket can hold 2500 mL. How many liters can the bucket hold?

• A. 0.25 L
• B. 25 L
• C. 2.5 L
• D. 250 L

Correct answer: C

Rationale: To convert milliliters (mL) to liters (L), you divide by 1000 since 1000 mL is equivalent to 1 liter. Therefore, 2500 mL is equal to 2.5 liters (2500 mL ÷ 1000 = 2.5 L). Choice A (0.25 L) is incorrect as it represents a conversion error by a factor of 10. Choice B (25 L) is incorrect as it incorrectly multiplies instead of dividing by 1000. Choice D (250 L) is incorrect as it overestimates the conversion by a factor of 100.

3. Which of the following statements regarding macrophages is incorrect?

• A. They are found abundantly in the blood
• B. They are larger than neutrophils
• C. They are long-lived
• D. They are made in the bone marrow as monocytes, called macrophages once they reach organs

Correct answer: A

Rationale: The correct answer is A. Macrophages are not found abundantly in the blood; they are present in tissues and organs. Macrophages are tissue-resident immune cells that play a key role in immune responses and are derived from monocytes produced in the bone marrow. Choice B is correct as macrophages are larger than neutrophils. Choice C is correct as macrophages are long-lived cells. Choice D is correct as macrophages originate in the bone marrow as monocytes and differentiate into macrophages once they migrate to various tissues and organs.

4. As the tour group approached the bottom of Chichen Itza, the prodigious Mayan pyramid, they became nervous about climbing its distant peak. Based on the context of the sentence, which of the following words shows the correct meaning of the word prodigious?

• A. Very large
• B. Famous
• C. Very old
• D. Fancy

Correct answer: A

Rationale: In this context, the word 'prodigious' is used to describe the Mayan pyramid at Chichen Itza. The tour group's nervousness about climbing its distant peak indicates that the pyramid is impressive in size and scale, invoking a sense of awe or grandeur. Therefore, the correct meaning of 'prodigious' in this context would be 'very large.' Choice B, 'Famous,' is incorrect as the sentence focuses on the size rather than the fame of the pyramid. Choice C, 'Very old,' and choice D, 'Fancy,' do not accurately capture the intended meaning of 'prodigious' as used in this context.

5. What are the fluid-filled sacs that cushion the brain within the skull called?

• A. Meninges
• B. Cerebrospinal fluid
• C. Dura mater
• D. Arachnoid mater

Correct answer: B

Rationale: The correct answer is B, cerebrospinal fluid. Cerebrospinal fluid acts as a shock absorber, protecting the brain from impact and providing nutrients to brain cells. Meninges are the three protective layers of tissue that surround the brain and spinal cord. Dura mater and arachnoid mater are specific layers of the meninges, not the fluid-filled sacs that cushion the brain.
