1. The author's tone towards UBI can be described as

• A. Strongly supportive, advocating for its immediate implementation without reservations.
• B. Strongly critical, highlighting only the potential drawbacks and dismissing its benefits.
• C. Neutral and objective, presenting both sides of the argument without taking a stance.
• D. Cautiously optimistic, acknowledging both the potential and challenges while calling for further discussion.

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

2. Your hypothesis predicts that exposing plants to classical music will enhance their growth. How could you design an experiment to test this hypothesis?

• A. Play classical music to all plants in the greenhouse and compare their growth to a control group without music.
• B. Select plants with personal preferences for classical music and compare their growth to plants who dislike it.
• C. Play different genres of music to separate plants and analyze which genre promotes the most growth.
• D. Observe the behavior of plants listening to music and measure their happiness levels.

Correct answer: A

Rationale: To test the hypothesis that exposing plants to classical music enhances their growth, the most appropriate experimental design would be to play classical music to all plants in the greenhouse (experimental group) and compare their growth to a control group of plants that are not exposed to any music. This design allows for a direct comparison between the effects of classical music exposure on plant growth, eliminating confounding variables that may arise from individual plant preferences or different music genres.

3. Aromatic compounds

• A. Contain a ring structure with alternating single and double bonds
• B. Readily undergo addition reactions
• C. Are easily broken down by water
• D. Do not contain any pi (Ï€) bonds

Correct answer: A

Rationale: The correct answer is A: 'Aromatic compounds contain a ring structure with alternating single and double bonds.' Aromatic compounds exhibit a special stability due to the delocalization of pi electrons within the ring, known as resonance. This resonance occurs because of the alternating single and double bonds in the ring structure, making them less reactive towards addition reactions compared to alkenes, which have only double bonds. This stability also makes aromatic compounds less likely to be easily broken down by water, as they are relatively inert in many chemical reactions. Therefore, aromatic compounds do contain pi (π) bonds due to the presence of the alternating single and double bonds in their ring structure.

4. Imaginary unit multiples are used to represent numbers that cannot be obtained on the number line. Which of the following is equivalent to 5i?

• A. -5
• B. i^5
• C. 5√-1
• D. 1/5i

Correct answer: C

Rationale: Rationale: - The imaginary unit, denoted as "i," is defined as the square root of -1. - Therefore, 5i can be expressed as 5 times the square root of -1, which is equivalent to 5√-1. - Option A, -5, is a real number and not an imaginary unit multiple. - Option B, i^5, is equal to i because i raised to any power that is a multiple of 4 results in 1, and i^5 is equivalent to i. - Option D, 1/5i, is the reciprocal of 5i and not equivalent to 5i.

5. Which division of the nervous system is responsible for involuntary functions such as heart rate, digestion, and respiratory rate?

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

Correct answer: b

Rationale: The correct answer is B: Autonomic nervous system. The autonomic nervous system is responsible for regulating involuntary functions in the body, such as heart rate, digestion, respiratory rate, and other automatic processes. The somatic nervous system (A) controls voluntary muscle movements, the peripheral nervous system (C) consists of nerves outside the brain and spinal cord, and the central nervous system (D) includes the brain and spinal cord. Understanding the functions and divisions of the nervous system is crucial for grasping how different bodily processes are controlled and regulated.

6. Discern the INCORRECT function of the liver.

• A. Bile production, aiding digestion.
• B. Blood protein synthesis, such as albumin.
• C. Glucose storage for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.
