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. The energy absorbed during a chemical reaction is called:

• A. Kinetic energy
• B. Potential energy
• C. Heat energy
• D. Endothermic energy

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

3. What are isotopes?

• A. Atoms of the same element with different numbers of protons.
• B. Atoms of the same element with different numbers of neutrons.
• C. Atoms of different elements with the same number of protons.
• D. Atoms of different elements with the same number of electrons.

Correct answer: B

Rationale: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes have the same atomic number (Z) but different mass numbers (A). For example, carbon-12 (¹²C), carbon-13 (¹³C), and carbon-14 (¹⁴C) are all isotopes of carbon. They all have six protons in their nuclei, but they have different numbers of neutrons: carbon-12 has six neutrons, carbon-13 has seven neutrons, and carbon-14 has eight neutrons.

4. What phenomenon explains the bending of light as it passes around an obstacle or through an aperture?

• A. Refraction
• B. Reflection
• C. Diffraction
• D. Dispersion

Correct answer: c

Rationale: Diffraction refers to the bending of light waves as they encounter an obstacle or pass through an aperture, causing the light to spread out.

5. Which element is a good conductor of electricity but is not a metal?

• A. Copper
• B. Silver
• C. Graphite
• D. Gold

Correct answer: C

Rationale: While metals are known for their conductivity, some non-metals like graphite also exhibit this property due to their unique electronic structure

6. What is the formula for calculating density?

• A. Density = Volume / Mass
• B. Density = Mass × Volume
• C. Density = Mass / Volume
• D. Density = Volume - Mass

Correct answer: c

Rationale: Density is defined as the mass of a substance divided by its volume. The formula for density is Density = Mass / Volume.
