1. Which part of the neuron insulates and speeds up the transmission of nerve impulses along the axon?

• A. Dendrite
• B. Myelin sheath
• C. Synapse
• D. Cell body

Correct answer: B

Rationale: The myelin sheath is a fatty layer that surrounds the axon of a neuron, providing insulation and speeding up the transmission of nerve impulses. This insulation helps prevent the loss of electrical signals as they travel along the axon, allowing for faster and more efficient communication within the nervous system. Dendrites are branching extensions of a neuron that receive signals from other neurons, the synapse is the junction between two neurons where communication occurs, and the cell body contains the nucleus and organelles of the neuron, but none of these structures provide insulation for the transmission of nerve impulses along the axon.

2. When it gets warm in the spring, _______ and _______ like to go fishing at Cobbs Creek. Which of the following word pairs should be used in the blanks above?

• A. me, him
• B. he, I
• C. him, I
• D. he, me

Correct answer: C

Rationale: The correct word pair to use in this context is 'him, I.' This is because 'him' and 'I' are the correct pronouns to refer to two individuals in the third person (him) and first person (I). The sentence should indicate that when it gets warm in the spring, 'him' and 'I' like to go fishing at Cobbs Creek. Choice A, 'me, him,' is incorrect as 'me' should be replaced with 'I' to maintain proper subject-object agreement. Choice B, 'he, I,' is incorrect as 'he' should be replaced with 'him' to properly refer to the other person involved. Choice D, 'he, me,' is incorrect as 'me' should be replaced with 'I' to maintain the correct pronoun usage.

3. Which of the following terms means toward the front of the body?

• A. Superior
• B. Anterior
• C. Inferior
• D. Posterior

Correct answer: B

Rationale: The correct answer is B: Anterior. The term 'anterior' specifically refers to the front of the body. In anatomical terms, anterior is the opposite of posterior, which means toward the back of the body. Superior and inferior, choices A and C, respectively, refer to top and bottom directions, not front and back. Therefore, 'Anterior' is the most appropriate term for describing a position toward the front of the body.

4. Solve for x: 3(x + 4) = 18

• A. x = 2
• B. x = 4
• C. x = 6
• D. x = 8

Correct answer: C

Rationale: To solve the equation 3(x + 4) = 18, first distribute the 3 to both terms inside the parentheses: 3x + 12 = 18. Next, isolate the variable x by subtracting 12 from both sides: 3x = 6. Finally, divide by 3 to solve for x, giving x = 6. Choice A, x = 2, is incorrect as the correct solution is x = 6. Choices B (x = 4) and D (x = 8) are also incorrect as they do not satisfy the given equation.

5. In the sentence “Bess, who can draw beautifully, loves art; but Grace, who thinks very logically, prefers science,” what type of sentence structure is being used?

• A. Compound-complex
• B. Compound
• C. Complex
• D. Simple

Correct answer: C

Rationale: The correct answer is C, complex. This sentence contains an independent clause ('Bess loves art') and a dependent clause ('who can draw beautifully'). The dependent clause relies on the independent clause for context and cannot stand alone as a complete sentence. The connection between the clauses is established by the relative pronoun 'who.' Choices A, B, and D are incorrect. It is not a compound-complex sentence as it lacks multiple independent clauses and a dependent clause, respectively. It is not a compound sentence since it does not have two independent clauses joined by a coordinating conjunction. Lastly, it is not a simple sentence because it contains both an independent and a dependent clause, making it more complex than a simple sentence.
