1. The term "unconditional" in the context of UBI signifies that

• A. The amount received would be based on individual income and living expenses.
• B. Recipients would be required to meet certain criteria to qualify for the program.
• C. The money would be provided without any restrictions on how it is spent.
• D. The program would be temporary and subject to periodic review and renewal.

Correct answer: C

Rationale: The unconditional aspect of UBI refers to the lack of strings attached to its receipt, aligning with C.

2. What is the unit of measurement for momentum?

• A. Newton-second (N·s)
• B. Kilogram-meter (kg·m)
• C. Joule (J)
• D. Meter per second (m/s)

Correct answer: A

Rationale: Momentum is defined as the product of an object's mass and its velocity. The unit of mass is kilograms (kg) and the unit of velocity is meters per second (m/s). Therefore, the unit of momentum is kilogram-meter per second (kg·m/s). By Newton's second law of motion (F = ma), force is measured in Newtons (N), which is equivalent to kg·m/s². Therefore, multiplying the unit of force (N) by the unit of time (s) gives the unit of momentum as Newton-second (N·s).

3. 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.

4. The scientist discovered a new species of butterfly in the rainforest. What is the past tense of the verb "discover"?

• A. discovers
• B. discovered
• C. discovering
• D. discovery

Correct answer: B

Rationale: The past tense of a verb describes an action that happened in the past.

5. A bar graph shows the number of patients admitted to the ER each day for a week. How do you determine the day with the highest number of admissions?

• A. Find the tallest bar in the graph.
• B. Compare the heights of all bars.
• C. Calculate the average number of admissions per day.
• D. Subtract the lowest number of admissions from the highest.

Correct answer: A

Rationale: The best approach is to find the tallest bar

6. What is the main reason why elements in Group 18 (Noble gases) are generally unreactive?

• A. They have high atomic masses
• B. They lack valence electrons
• C. Their outermost electron shells are completely filled
• D. They exist as single atoms, not molecules

Correct answer: C

Rationale: Noble gases have their outermost electron shells filled with 8 electrons, achieving a stable configuration with minimal urge to gain or lose electrons, making them less prone to chemical reactions.
