1. Which of the following is not part of the central nervous system?

• A. Retina
• B. Spinal cord
• C. Brain
• D. Heart

Correct answer: B

Rationale: The central nervous system consists of the brain and spinal cord, which are responsible for processing and coordinating information. The retina is part of the eye, while the heart is part of the circulatory system. Therefore, the correct answer is 'Spinal cord' as it is not part of the central nervous system.

2. What is the primary function of the circulatory system?

• A. To produce hormones
• B. To transport oxygen and nutrients
• C. To fight infections
• D. To regulate body temperature

Correct answer: B

Rationale: The circulatory system's primary function is to transport oxygen, nutrients, and hormones to cells and remove waste products. Choice A is incorrect because hormone production is primarily carried out by endocrine glands. Choice C is incorrect as fighting infections is a role of the immune system. Choice D is incorrect as regulating body temperature is mainly controlled by the integumentary and nervous systems.

3. Which word is used incorrectly in the following sentence? Professor Turnbull will apprise us of the correct procedure for submitting our work.

• A. appraise
• B. correct
• C. procedure
• D. submitting

Correct answer: A

Rationale: The word 'apprise' is used incorrectly in the sentence. The correct word to use in this context is 'appraise,' which means to assess the value or quality of something, such as appraising the worth of an item. 'Apprise' means to inform or notify someone about something. Therefore, 'appraise' is the correct word choice. Choices B, C, and D are all used appropriately in the sentence and do not need to be changed.

4. Select the meaning of the word 'overt' in the sentence: 'Despite the absence of overt signs, Dr. Harris suspected Alicia might be suffering from the flu.'

• A. concealed
• B. apparent
• C. expert
• D. delectable

Correct answer: B

Rationale: The correct answer is B: 'apparent.' In the given sentence, 'overt' is used to describe signs that are evident or obvious. It indicates that Dr. Harris suspected Alicia might have the flu even though there were no clear or overt signs present. Choice A, 'concealed,' is incorrect as it means hidden or not easily visible, which is the opposite of 'overt.' Choices C and D, 'expert' and 'delectable,' are unrelated to the meaning of 'overt' in this context.

5. If Randy sells 8 times as many vacuum cleaners as Janice, and Janice sells 690 vacuum cleaners per year, on average, how many does Randy sell each month?

• A. 4,600
• B. 5,520
• C. 6,400
• D. 8,320

Correct answer: B

Rationale: If Janice sells 690 vacuum cleaners per year, Randy sells 8 times that amount, which is 690 x 8 = 5,520 vacuum cleaners per year. To find out how many Randy sells each month, you divide 5,520 by 12 (months), which equals 460 vacuum cleaners per month. Therefore, Randy sells 5,520 vacuum cleaners per year divided by 12 months, which equals 460 vacuum cleaners per month. Choices A, C, and D are incorrect as they do not reflect the correct calculation based on the information provided.
