1. What is the correct plural of century?

• A. Centurys
• B. Centures
• C. Centuries
• D. Centuryies

Correct answer: C

Rationale: The correct plural of 'century' is 'centuries'. In English, to form the plural of most nouns ending in -y, you change the -y to -ies. Choice A, 'Centurys', is incorrect because it does not follow this rule. Choice B, 'Centures', is also incorrect as it does not provide the correct plural form. Choice D, 'Centuryies', is a completely incorrect and non-standard plural form of 'century'. Therefore, the correct answer is 'Centuries'.

2. Which of the following is true regarding T cells?

• A. They are only seen in individuals with leukemia.
• B. They are a specialized type of white blood cell.
• C. They mature in the thymus.
• D. They play a role in the immune response.

Correct answer: D

Rationale: The correct answer is D: T cells are a specialized type of white blood cell that play a crucial role in the immune response. They are produced in the bone marrow and mature in the thymus gland. T cells help coordinate and regulate the immune response to pathogens and foreign substances by interacting with other immune cells. Choices A, B, and C are incorrect. T cells are not exclusively seen in individuals with leukemia; they are a normal component of the immune system found in healthy individuals. While it is true that T cells are a specialized type of white blood cell, the key characteristic being tested in this question is their role in the immune response. Lastly, T cells do mature in the thymus, but this alone does not encompass the full scope of their function in the immune system.

3. What is the mode of the set of numbers {4, 4, 5, 7, 8}?

• A. 4
• B. 5
• C. 7
• D. 8

Correct answer: A

Rationale: The mode of a set of numbers is the value that appears most frequently. In the given set {4, 4, 5, 7, 8}, the number 4 appears twice, which is more frequent than any other number. Therefore, the mode of this set is 4. Choice B, 5, is incorrect as it only appears once in the set. Choices C and D, 7 and 8 respectively, also appear only once each, making them less frequent than the number 4.

4. What is the primary function of nephrons?

• A. Store urine
• B. Filter blood and remove waste products
• C. Produce hormones
• D. Control blood pressure

Correct answer: B

Rationale: Nephrons are the functional units of the kidneys responsible for filtering blood to remove waste products, excess ions, and water. This process leads to the formation of urine, aiding in maintaining the body's fluid and electrolyte balance. The primary function of nephrons is not to store urine but to filter blood and eliminate waste products. Choice C, 'Produce hormones,' is incorrect as nephrons primarily focus on filtration rather than hormone production. Choice D, 'Control blood pressure,' is also incorrect as while the kidneys do play a role in regulating blood pressure, it is not the primary function of nephrons within the kidneys.

5. Based on the information provided, what is the most logical reason for the watering schedule having the same number for both Friday and Saturday?

• A. There are more addresses ending with these numbers than with the other numbers.
• B. All businesses have addresses ending in these numbers, and they consume the most water.
• C. The residents at these addresses are the most likely to consume more water.
• D. The city is more concerned about water usage in the latter part of the week.

Correct answer: C

Rationale: The most logical reason for the watering schedule having the same number for both Friday and Saturday is that the residents at addresses ending with these numbers are the most likely to consume more water. This indicates a trend in water consumption among residents at these specific addresses, leading to the need for consistent watering on both days. Choice A is incorrect as the number of addresses ending with specific numbers does not necessarily correlate with water consumption. Choice B is incorrect as there is no information suggesting that businesses consuming the most water have addresses ending with these numbers. Choice D is incorrect as there is no evidence to support that the city is more concerned about water usage specifically in the latter part of the week.
