1. Which type of cell secretes antibodies?

• A. Bacterial cells
• B. Viral cells
• C. Lymph cells
• D. Plasma cells

Correct answer: D

Rationale: The correct answer is D: Plasma cells. Plasma cells are a type of white blood cell that secretes antibodies. Antibodies are essential components of the immune system, as they help in identifying and neutralizing pathogens. Choice A, B, and C are incorrect as bacterial cells and viral cells do not secrete antibodies, and lymph cells are involved in the immune response but do not secrete antibodies like plasma cells.

2. What is the range in the number of flights made per month by the flight attendant?

• A. 20
• B. 25
• C. 29
• D. 32

Correct answer: C

Rationale: The range is calculated by finding the difference between the highest and lowest values. In this case, the highest number of flights made per month is 32, and the lowest is 3. Therefore, the range is 32 - 3 = 29. Choice C, '29', is the correct answer. Choice A, '20', Choice B, '25', and Choice D, '32', are incorrect as they are individual data points and do not represent the range, which is a measure of spread between the highest and lowest values.

3. Which of the following sentences correctly uses a second-person narrative voice?

• A. You go to the window because someone is knocking insistently on the front door.
• B. I go to the window because someone is knocking on the door.
• C. He goes to the window because someone is knocking.
• D. They go to the window because someone is knocking.

Correct answer: A

Rationale: The correct answer is A because it correctly uses the second-person narrative voice by addressing the reader as 'you,' directly involving them in the action. Choices B, C, and D use first-person ('I'), third-person singular ('he'), and third-person plural ('they') perspectives, respectively, which do not align with a second-person narrative voice. It is essential to identify the perspective being used in a sentence to determine if it matches the criteria specified in the question.

4. What is a major structure of the limbic system?

• A. Brainstem
• B. Spinal cord
• C. Hypothalamus
• D. Cerebral cortex

Correct answer: C

Rationale: The correct answer is C: Hypothalamus. The hypothalamus is a significant structure of the limbic system responsible for regulating various functions such as emotions, autonomic functions, and hormone production. It plays a crucial role in maintaining homeostasis and orchestrating responses to stress and emotional stimuli. Choices A, B, and D are incorrect. The brainstem, although a vital part of the brain, is not a major structure of the limbic system. The spinal cord is not part of the limbic system; it is primarily involved in transmitting sensory and motor information between the brain and the rest of the body. The cerebral cortex is responsible for higher cognitive functions but is not a major structure within the limbic system.

5. Which of the following values is the greatest?

• A. 2/11
• B. 5.4
• C. 13/3
• D. 6.25

Correct answer: D

Rationale: To determine the greatest value among the given options, convert the fractions to decimal form. 2/11 is approximately 0.1818, 5.4 is a decimal itself, 13/3 is approximately 4.333, and 6.25 is a decimal. Comparing these values, 6.25 is the largest among them. Therefore, option D, 6.25, is the correct answer. Choices A, B, and C are smaller values compared to 6.25, making them incorrect answers.
