1. Which component of the nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles?

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

Correct answer: C

Rationale: The correct answer is C: Somatic nervous system. The somatic nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles. This system consists of motor neurons that send signals from the central nervous system to the skeletal muscles, allowing for conscious control over movement. The autonomic nervous system (A) controls involuntary functions like heart rate and digestion, the peripheral nervous system (B) includes all nerves outside the central nervous system, and the sympathetic nervous system (D) is a division of the autonomic nervous system responsible for the fight-or-flight response. Therefore, choices A, B, and D are incorrect as they do not specifically regulate voluntary movements of skeletal muscles, which is a function of the somatic nervous system.

2. Which of the following is not an example of something the author of Passage 1 claims travels from place to place through human environment?

• A. Fairy tales
• B. Language
• C. Ideas
• D. Foods

Correct answer: D

Rationale: The correct answer is D: Foods. The author of Passage 1 mentions language, ideas, and goods as examples of things that travel from place to place through the movement of peoples. There is no mention of food in the passage as something that is spread through human interaction. Fairy tales, language, and ideas are specifically highlighted in the text as elements that are transmitted through human interaction. While foods can be exchanged between cultures, the passage does not discuss them in the context of spreading through human interaction, making it the correct answer. Choice A (Fairy tales), B (Language), and C (Ideas) are all supported by the text as examples of things that travel through human environments, unlike food.

3. What is the dermis composed of?

• A. Adipose tissue
• B. Epithelial cells
• C. Connective tissue
• D. Muscle tissue

Correct answer: C

Rationale: The correct answer is C: Connective tissue. The dermis is primarily composed of connective tissue, which includes collagen and elastin fibers that provide strength and elasticity to the skin. It houses blood vessels, nerve endings, hair follicles, and glands, playing a crucial role in supporting the skin structure and function. Adipose tissue (choice A) is found in the subcutaneous layer beneath the dermis, providing insulation and energy storage. Epithelial cells (choice B) form the outermost layer of the skin called the epidermis. Muscle tissue (choice D) is not a significant component of the dermis but is found deeper in the body associated with movement and support.

4. Which of the following words does the author use to express a derogatory tone?

• A. Predictable
• B. Noisy
• C. Delicate
• D. Roar

Correct answer: A

Rationale: The correct answer is 'Predictable' because the author uses it in a negative context to imply something as uninspired or lacking creativity. In the passage, the author mentions that following rules can make writing difficult, contrasting writers who adhere to rules with those who break them to succeed. 'Predictable' reflects a derogatory tone as it suggests monotony or lack of originality. Choices B, C, and D do not convey a derogatory tone in the context of the passage. 'Noisy,' 'Delicate,' and 'Roar' are neutral or descriptive words that do not carry a negative connotation.

5. What is the main target organ for insulin, the hormone produced by the pancreas?

• A. Liver
• B. Kidneys
• C. Muscles
• D. Brain

Correct answer: C

Rationale: The main target organ for insulin is muscles. Insulin plays a crucial role in regulating glucose metabolism by promoting the uptake of glucose into muscle cells. This glucose can then be utilized for energy production or stored for later use. Therefore, muscles are the primary site where insulin exerts its effects on glucose uptake and utilization. The liver primarily responds to insulin by regulating glucose storage and release, but the main target for insulin-mediated glucose uptake is muscles. Kidneys are not a target organ for insulin action in glucose metabolism. The brain does not heavily rely on insulin for glucose uptake as it primarily uses glucose independently of insulin for energy production.
