1. Which term refers to the surgical removal of an organ's contents?

• A. Excretion
• B. Evisceration
• C. Incision
• D. Reduction

Correct answer: B

Rationale: The correct answer is B, 'Evisceration.' Evisceration specifically means the surgical removal of an organ's contents. Choice A, 'Excretion,' is the process of eliminating waste products from the body and is not related to surgical procedures. Choice C, 'Incision,' refers to the act of cutting into the body, commonly done in surgeries but not specifically related to removing organ contents. Choice D, 'Reduction,' generally means to make something smaller or lessen its size, which is not the term used for the surgical removal of an organ's contents.

2. When a person finds ________________ in a stressful situation, it helps to breathe deeply.

• A. Oneself
• B. Yourself
• C. Themselves
• D. Itself

Correct answer: A

Rationale: In this sentence, 'Oneself' is the correct reflexive pronoun to use when referring back to the singular subject 'a person.' It is important to match the reflexive pronoun with the singular noun. 'Yourself' and 'Themselves' are plural forms and do not agree with the singular subject 'a person.' 'Itself' is used for inanimate objects, not for people. Therefore, 'Oneself' is the most suitable choice in this context.

3. Subtract: 15.7 - 9.8 =

• A. 6.1
• B. 8.96
• C. 5.9
• D. 4.30

Correct answer: C

Rationale: To find the difference between 15.7 and 9.8, you need to subtract 9.8 from 15.7. This operation results in 5.9. Therefore, the correct answer is 5.9. Choice A, 6.1, is incorrect as it represents the result of subtracting 9.8 from 15.9, not 15.7. Choice B, 8.96, is also incorrect as it is not the correct result of the subtraction provided. Choice D, 4.30, is incorrect as well, as it is not the result of subtracting 9.8 from 15.7.

4. A rock has a volume of 6 cm3 and a mass of 24 g. What is its density?

• A. 4 g/cm3
• B. 4 cm3/g
• C. 144 g/cm3
• D. 144 cm3/g

Correct answer: A

Rationale: Density is calculated by dividing the mass of an object by its volume. In this case, the mass of the rock is 24 g and its volume is 6 cm3. By dividing 24 g by 6 cm3, we find that the density of the rock is 4 g/cm3. Choice A is the correct answer because density is expressed in units of mass per unit volume (g/cm3). Choice B is incorrect as it represents the reciprocal of density. Choices C and D are significantly higher values and do not match the calculated density of the rock.

5. Which part of the brain controls voluntary movement?

• A. Cerebellum
• B. Cerebrum
• C. Brainstem
• D. Medulla oblongata

Correct answer: B

Rationale: The cerebrum, specifically the motor cortex located within it, is responsible for controlling voluntary movements such as walking, writing, and speaking. This region of the brain plays a crucial role in coordinating and executing voluntary muscle actions, making it the correct answer in this context. The cerebellum (Choice A) primarily coordinates balance, posture, and coordination of voluntary movements but does not control voluntary movement itself. The brainstem (Choice C) is responsible for basic life functions like breathing and heart rate, not voluntary movements. The medulla oblongata (Choice D) controls vital functions like blood pressure and breathing, not voluntary movement.
