1. The final sentence suggests that the debate surrounding UBI necessitates

• A. Focusing on the potential cost savings for governments compared to existing welfare programs.
• B. Prioritizing the opinions of economists and financial experts over those of social scientists and philosophers.
• C. Engaging in thoughtful and informed discussions considering both the economic and ethical implications.
• D. Dismissing the concerns of critics and implementing UBI as a rapid solution to poverty and inequality.

Correct answer: C

Rationale: The emphasis on "complex interplay" and "careful consideration" suggests a call for nuanced and multifaceted discussions, aligning with C.

2. Which part of the brainstem controls heart rate and breathing?

• A. Medulla oblongata
• B. Pons
• C. Midbrain
• D. Thalamus

Correct answer: B

Rationale: The correct answer is B: Pons. The pons is a part of the brainstem located above the medulla oblongata and plays a crucial role in controlling vital functions such as heart rate and breathing. It contains neural circuits that regulate the rhythmic patterns of breathing and works in coordination with the medulla oblongata to ensure proper respiratory function. While the medulla oblongata is also involved in regulating these functions, the pons is more specifically responsible for fine-tuning and coordinating the activity of these essential processes.

3. In the female reproductive system, what structure produces eggs (ova)?

• A. Fallopian tubes
• B. Ovaries
• C. Uterus
• D. Vagina

Correct answer: A

Rationale: The correct answer is B: Ovaries. The ovaries are the primary reproductive organs in the female body responsible for producing eggs (ova) through a process called ovulation. The fallopian tubes serve as the passageway for the egg to travel from the ovary to the uterus for potential fertilization. The uterus is where a fertilized egg implants and develops into a fetus during pregnancy. The vagina is the muscular canal that connects the uterus to the outside of the body and serves as the birth canal during childbirth. Therefore, the ovaries are specifically responsible for the production of eggs in the female reproductive system.

4. How many moles of water are produced when 0.5 moles of methane (CH4) react with excess oxygen?

• A. 0.5 moles
• B. 1 mole
• C. 2 moles
• D. 3 moles

Correct answer: c

Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, indicating a 1:2 ratio between CH4 and H2O.

5. Imagine you have an element with atomic number 20 and mass number 40. How many neutrons does it have?

• A. 20
• B. 40
• C. 10
• D. 20

Correct answer: C

Rationale: Rationale: - The atomic number (Z) represents the number of protons in an atom. In this case, the atomic number is 20. - The mass number (A) represents the total number of protons and neutrons in an atom. In this case, the mass number is 40. - To find the number of neutrons, you subtract the atomic number from the mass number: Neutrons = Mass number - Atomic number. - Neutrons = 40 - 20 = 20. - Therefore, the element with atomic number 20 and mass number 40 has 20 neutrons.

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.
