1. What is the protective fluid that surrounds the brain and spinal cord?

• A. Blood
• B. Cerebrospinal fluid
• C. Myelin sheath
• D. Insulin

Correct answer: B

Rationale: Cerebrospinal fluid is the protective fluid that surrounds the brain and spinal cord. It acts as a cushion to protect these vital organs from injury and provides nutrients and removes waste products. Blood, myelin sheath, and insulin do not serve as the protective fluid surrounding the brain and spinal cord. Blood carries nutrients and oxygen to cells, myelin sheath is a protective covering of nerve fibers, and insulin is a hormone involved in regulating blood sugar levels.

2. Which of the following demonstrates correct punctuation?

• A. Graham still needs the following items for his class: a sable brush, soft pastels, a sketchbook, and an easel.
• B. Graham still needs the following items for his class, a sable brush, soft pastels, a sketchbook, and an easel.
• C. Graham still needs the following items for his class: a sable brush; soft pastels; a sketchbook; and an easel.
• D. Graham still needs the following items for his class – a sable brush; soft pastels; a sketchbook; and an easel.

Correct answer: A

Rationale: Choice A demonstrates correct punctuation. The sentence uses a colon to introduce a list, which is the most appropriate punctuation in this context. A colon is typically used to signal that a list or explanation follows, making it the suitable choice here. Choices B, C, and D either use a comma, semi-colon, or dash incorrectly to introduce the list, deviating from the standard punctuation rule for listing items. Therefore, they are incorrect in the context of this sentence.

3. 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.

4. Which of the following prefixes means 'with'?

• A. bio-
• B. per-
• C. con-
• D. trans-

Correct answer: C

Rationale: The correct answer is C: 'con-'. The prefix 'con-' means 'with' or 'together,' as in words like 'convene' or 'connect.' Choice A, 'bio-', is a prefix that means 'life' or 'living organisms,' not 'with.' Choice B, 'per-', is a prefix that means 'through' or 'thoroughly,' not 'with.' Choice D, 'trans-', is a prefix that means 'across' or 'beyond,' not 'with.' Therefore, the correct choice that means 'with' is 'con-'.

5. Which of the following is a characteristic of an interneuron?

• A. Forms neural circuits
• B. Interacts with effectors
• C. Sends impulses to the CNS
• D. Functions as an efferent nerve cell

Correct answer: A

Rationale: The correct characteristic of an interneuron is that it forms neural circuits, connecting sensory and motor neurons within the central nervous system. Interneurons facilitate communication between different neurons in the central nervous system, helping in the processing and integration of signals. Choice B is incorrect as interneurons primarily interact with other neurons, not effectors. Choice C is incorrect as interneurons typically do not send impulses to the CNS; they operate within the CNS. Choice D is incorrect as interneurons are not efferent nerve cells; they are mainly involved in processing signals within the CNS rather than transmitting signals to effectors.
