1. Which form of energy is associated with the motion of an object?

• A. Kinetic energy
• B. Potential energy
• C. Thermal energy
• D. Electrical energy

Correct answer: a

Rationale: Kinetic energy is the energy of motion possessed by an object.

2. What is the name of a condition where the immune system mistakenly attacks healthy body tissues?

• A. Allergy
• B. Autoimmune disease
• C. Immunodeficiency
• D. Sepsis

Correct answer: B

Rationale: The correct answer is B: Autoimmune disease. This condition occurs when the immune system mistakenly targets and attacks healthy tissues in the body, leading to inflammation and tissue damage. Autoimmune diseases can affect various organs and systems in the body, such as rheumatoid arthritis, lupus, and multiple sclerosis. Allergies (A) involve the immune system overreacting to harmless substances, but they do not involve attacking healthy tissues. Immunodeficiency (C) refers to a weakened immune system that is less able to fight off infections. Sepsis (D) is a life-threatening condition caused by the body's response to an infection, not an autoimmune reaction.

3. Which word best describes the relationship between population growth and smart cities in the passage?

• A. Cause and effect
• B. Analogy
• C. Contrast
• D. Similarity

Correct answer: A

Rationale: The passage identifies rapid population growth as a challenge that smart cities are proposed to address, establishing a causal connection.

4. 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.

5. Which type of energy is possessed by an object in motion?

• A. Potential energy
• B. Kinetic energy
• C. Thermal energy
• D. Chemical energy

Correct answer: b

Rationale: Kinetic energy is the energy possessed by an object in motion.

6. What information can be obtained directly from the element's atomic number?

• A. Its atomic mass
• B. Its position on the periodic table
• C. Its position on the periodic table
• D. Its chemical properties

Correct answer: B

Rationale: The atomic number of an element represents the number of protons in the nucleus of an atom. This number determines the element's unique identity and its position on the periodic table. The atomic mass (option A) is not directly determined by the atomic number but is a weighted average of the isotopes of an element. The position on the periodic table (option C) is directly related to the atomic number, as elements are arranged in order of increasing atomic number. The chemical properties of an element (option D) are influenced by the number of protons in the nucleus, which is determined by the atomic number.
