1. Which division of the nervous system is responsible for the 'fight or flight' response, preparing the body to respond to stressful situations?

• A. Somatic nervous system
• B. Autonomic nervous system
• C. Peripheral nervous system
• D. Central nervous system

Correct answer: B

Rationale: The autonomic nervous system is correctly identified as the division responsible for the 'fight or flight' response, which readies the body to react to stressful situations. This system regulates involuntary bodily functions, such as heart rate, pupil dilation, and adrenaline release during stress. The somatic nervous system controls voluntary movements and skeletal muscle activity, not the automatic responses seen in the 'fight or flight' reaction. The peripheral nervous system connects the central nervous system to the body's organs and limbs, facilitating communication, while the central nervous system, comprising the brain and spinal cord, serves as the primary control center of the body, integrating and processing information.

2. What is the median of the data set: 3, 5, 7, 9, 11?

• A. 3
• B. 7
• C. 9
• D. 5

Correct answer: B

Rationale: To find the median of a set of numbers, you arrange them in ascending order and then find the middle value. Given the data set 3, 5, 7, 9, 11, when arranged in ascending order, becomes 3, 5, 7, 9, 11. The middle value in this set is 7, making it the median. Choice A (3) is the smallest value, not the middle value. Choice C (9) and Choice D (5) are not the middle values of the set either. Therefore, the correct answer is B (7).

3. How many ounces are in 2 quarts?

• A. 8 ounces
• B. 32 ounces
• C. 16 ounces
• D. 64 ounces

Correct answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.

4. In experimental design, which variable is measured as a possible effect and is plotted on the y-axis?

• A. Independent, x
• B. Independent, y
• C. Dependent, x
• D. Dependent, y

Correct answer: D

Rationale: The correct answer is D: 'Dependent, y.' In experimental design, the dependent variable is the outcome that is being measured or observed as a result of changes in the independent variable. It is typically plotted on the y-axis of a graph to represent the effect or response to the changes in the independent variable. Choice A 'Independent, x' is incorrect because the independent variable is the variable manipulated by the experimenter and is usually plotted on the x-axis. Choice B 'Independent, y' is incorrect as the independent variable is not plotted on the y-axis. Choice C 'Dependent, x' is incorrect because the dependent variable is not typically plotted on the x-axis in experimental design.

5. Identify the type of clause in the sentence: 'I ate, and he drank.'

• A. Coordinate clause
• B. Dependent clause
• C. Subordinate clause
• D. Independent clause

Correct answer: A

Rationale: The correct answer is 'A: Coordinate clause.' In the sentence 'I ate, and he drank,' 'I ate' and 'he drank' are coordinate clauses. They are both independent clauses that are joined by the coordinating conjunction 'and.' A coordinate clause is a type of independent clause that is equally important and balanced within a sentence. A dependent clause cannot stand alone as a complete sentence and relies on an independent clause. A subordinate clause is a type of dependent clause that functions within a sentence to provide additional information but does not express a complete thought. An independent clause, on the other hand, can stand alone as a complete sentence.
