1. Which types of glial cells are in the PNS?

• A. Schwann cells, satellite cells
• B. Astrocytes, oligodendrocytes
• C. Microglia, ependymal cells
• D. Satellite cells, oligodendrocytes

Correct answer: A

Rationale: The correct answer is A, which includes Schwann cells and satellite cells as the types of glial cells found in the peripheral nervous system. Schwann cells support neurons and myelinate axons, while satellite cells provide structural support and regulate the microenvironment around neurons in the PNS. Options B, C, and D are incorrect as they refer to glial cell types that are typically found in the central nervous system, not the peripheral nervous system. Astrocytes and oligodendrocytes are primarily located in the CNS, where they perform functions such as providing structural support and forming the blood-brain barrier. Microglia are immune cells found in the CNS responsible for immune defense and maintenance of neural environment, while ependymal cells line the cerebral ventricles and the central canal of the spinal cord, contributing to the production and circulation of cerebrospinal fluid.

2. Which of the following phrases is grammatically correct and uses parallel structure?

• A. He enjoys reading, writing, and playing sports.
• B. Walking, swimming, and cooking are his favorite hobbies.
• C. He likes to read, write, and play sports.
• D. Singing, dancing, and traveling are his passions.

Correct answer: B

Rationale: Option B is the correct answer as it uses the gerund (-ing) form for all three hobbies, achieving parallel structure. Parallel structure requires that elements in a sentence are grammatically balanced. In this case, all three activities are presented in the same form, making the sentence clear and consistent. Choices A, C, and D do not exhibit parallel structure as they mix verb forms or use infinitives, breaking the parallelism needed for correct grammar.

3. What is a typical characteristic of male cicadas?

• A. They have short antennae and wide-set eyes.
• B. They respond with a clicking sound when ready to mate.
• C. They make strident, high buzzing sounds by vibrating two membranes on their abdomen.
• D. They deposit eggs into the bark after mating.

Correct answer: C

Rationale: Male cicadas are known for making strident, high buzzing sounds by vibrating two membranes on their abdomen, reaching up to 80 to 100 decibels, similar to the roar of a loud engine. This behavior is distinct to male cicadas and serves as a way to attract females for mating. Choice A is incorrect because it describes physical characteristics of cicadas, not behavior. Choice B is incorrect as it describes the behavior of female cicadas, not males. Choice D is incorrect as it pertains to the behavior of female cicadas after mating, not males.

4. What is a primary function of red blood cells?

• A. To fight infection
• B. To carry oxygen
• C. To produce antibodies
• D. To transport waste

Correct answer: B

Rationale: The main function of red blood cells is to carry oxygen from the lungs to all the body's tissues and organs, where it is needed for cellular functions and metabolism. This process is essential for sustaining life and providing energy to cells. Choice A is incorrect because fighting infection is primarily done by white blood cells. Choice C is incorrect because antibody production is mainly carried out by specialized white blood cells. Choice D is incorrect as the primary role of red blood cells is not to transport waste, but rather to transport oxygen and some carbon dioxide.

5. The Black Panther Party (BPP) was another activist group that formed around the same time as and was similar in function to the NAACP. What revision best improves this sentence?

• A. NO CHANGE
• B. was another activist group that
• C. had a lot of members that
• D. was another school that

Correct answer: B

Rationale: Describing the BPP as 'another activist group' provides clarity and relevance. Choice B correctly identifies the Black Panther Party as an activist group, aligning with its historical context and function. Choices C and D introduce irrelevant or inaccurate information, making them incorrect. Choice A, 'NO CHANGE,' leaves the sentence vague and does not provide the necessary clarification about the nature of the Black Panther Party.
