1. Which of the following would weaken the author's argument?

• A. a report revealing that the cited study was funded by a company that provides discounted tutoring through schools
• B. a study demonstrating differences in standardized test scores among students at schools in various neighborhoods
• C. a statement signed by local teachers affirming that they do not give preferential treatment in the classroom or during grading
• D. a study indicating that GPA has a weak correlation with success in college

Correct answer: A

Rationale: Choice A weakens the author's argument by highlighting a potential conflict of interest. If the cited study was funded by a company offering discounted tutoring, it could introduce bias and question the credibility of the study's findings. This revelation could cast doubt on the objectivity and reliability of the research, ultimately undermining the argument based on the cited study. Choices B, C, and D do not directly impact the credibility or objectivity of the cited study, so they would not significantly weaken the author's argument.

2. What is the primary function of the small intestine?

• A. To absorb water
• B. To absorb nutrients
• C. To store waste
• D. To produce enzymes

Correct answer: B

Rationale: The correct answer is B: "To absorb nutrients." The small intestine's primary function is to absorb nutrients from digested food. It plays a crucial role in the digestion and absorption of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals, which are essential for the body's functions and energy production. Choice A, "To absorb water," is incorrect because the absorption of water primarily occurs in the large intestine. Choice C, "To store waste," is incorrect as waste is stored in the large intestine before elimination. Choice D, "To produce enzymes," is incorrect because while the small intestine does receive enzymes from other organs to aid in digestion, its primary role is not enzyme production.

3. Which part of the brain is responsible for coordinating muscle movements, maintaining balance, and posture?

• A. Cerebrum
• B. Cerebellum
• C. Medulla oblongata
• D. Thalamus

Correct answer: B

Rationale: The correct answer is B, the cerebellum. The cerebellum plays a crucial role in coordinating muscle movements, maintaining balance, and posture. It receives inputs from sensory systems, the spinal cord, and other brain regions to fine-tune motor movements. The cerebrum, choice A, is primarily involved in higher brain functions like thinking and decision-making. The medulla oblongata, choice C, controls essential functions such as breathing and heart rate. The thalamus, choice D, serves as a relay center for sensory information but is not directly responsible for coordinating muscle movements, balance, or posture.

4. How many centimeters are in 4 meters?

• A. 40 cm
• B. 400 cm
• C. 4 cm
• D. 0.4 cm

Correct answer: B

Rationale: To convert meters to centimeters, you multiply by 100. In this case, 4 meters x 100 = 400 centimeters. Therefore, the correct answer is 400 cm. Choices A, C, and D are incorrect because they do not correctly convert meters to centimeters.

5. Which of the following is the outermost layer of the skin, providing protection against pathogens and the environment?

• A. Dermis
• B. Epidermis
• C. Hypodermis
• D. Stratum corneum (part of the epidermis)

Correct answer: B

Rationale: The epidermis is the correct answer as it is the outermost layer of the skin, providing protection against pathogens and the environment. It consists of multiple layers, including the stratum corneum, which is the outermost layer of the epidermis. The dermis is located beneath the epidermis, offering structural support and housing blood vessels, nerves, and glands. The hypodermis is the deepest layer of the skin, made up of fat and connective tissue that secures the skin to underlying structures. Choice A, Dermis, is incorrect as it is located beneath the epidermis. Choice C, Hypodermis, is incorrect as it is the deepest layer of the skin, not the outermost. Choice D, Stratum corneum (part of the epidermis), is not the correct answer as it is a specific layer within the epidermis and not the overall outermost layer of the skin.
