1. Acids are generally characterized by a sour taste and the ability to:

• A. Turn litmus paper blue
• B. Conduct electricity in solution
• C. Neutralize bases
• D. React explosively with metals

Correct answer: B

Rationale: Acids release hydrogen ions (H+) in solution, allowing electrical conductivity

2. Based on the passage, the author's stance on AI is likely to be

• A. Unconditionally enthusiastic, embracing all forms of AI development without reservations.
• B. Cautiously optimistic, acknowledging both the potential and risks while advocating for responsible use.
• C. Strongly critical, focusing solely on the potential dangers of AI and advocating for its complete halt.
• D. Apathetic and indifferent, lacking any strong opinion on the impact or future of AI.

Correct answer: B

Rationale: The emphasis on balancing benefits and risks suggests a cautious and balanced perspective, aligning with B.

3. The process of a gas changing into a liquid is called:

• A. Evaporation
• B. Boiling
• C. Condensation
• D. Sublimation

Correct answer: C

Rationale: Condensation happens when gas particles lose energy and slow down, transitioning into the liquid state.

4. he shimmering image of water seen on a hot road is a well-known example of:

• A. Reflection
• B. Refraction
• C. Interference
• D. Polarization

Correct answer: B

Rationale: The shimmering image of water seen on a hot road is a classic example of refraction. Refraction occurs when light waves pass from one medium to another, causing them to change direction due to the change in speed. In this scenario, the air above the road is hotter than the air closer to the ground, creating different densities of air which causes light to bend and distort, giving the illusion of water. Reflection, on the other hand, is the bouncing back of light waves from a surface, interference involves the superposition of two or more waves, and polarization is the orientation of light waves in a specific direction. Therefore, option B, refraction, is the correct answer in this case.

5. Which type of wave requires a medium to travel through?

• A. Electromagnetic waves
• B. Mechanical waves
• C. Sound waves
• D. Both a and c

Correct answer: d

Rationale: Both mechanical waves (such as sound waves) and electromagnetic waves (like light) have different requirements for propagation, but both can travel through a medium.

6. The axial skeleton consists of bones in the:

• A. Head, neck, and trunk
• B. Arms and legs
• C. Hands and feet
• D. All of the above

Correct answer: A

Rationale: The correct answer is A: 'Head, neck, and trunk.' The axial skeleton includes the bones along the body's central axis, comprising the skull, vertebral column, rib cage, and sternum. These bones provide structural support and protect vital organs. Choices B and C are incorrect as the arms, legs, hands, and feet are part of the appendicular skeleton. Therefore, the axial skeleton primarily encompasses the head, neck, and trunk, making option A the correct choice.
