1. The passage implies that achieving energy sustainability requires...

• A. solely relying on renewable energy sources for electricity generation.
• B. a combination of advancements in renewable energy production and management technologies.
• C. prioritizing economic benefits over environmental concerns when making energy choices.
• D. focusing solely on reducing energy consumption without addressing production sources.

Correct answer: B

Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.

2. Which of the following is NOT a type of epithelium

• A. Stratified squamous
• B. Simple cuboidal
• C. Stratified columnar
• D. Stratified columnar

Correct answer: D

Rationale: The correct answer is D, 'Stratified columnar.' Epithelial tissues are classified based on their structure and function. Stratified squamous epithelium consists of multiple layers of flattened cells and is found in areas that need protection, like the skin. Simple cuboidal epithelium is a single layer of cube-shaped cells that function in secretion and absorption, commonly found in kidney tubules. Stratified columnar epithelium is a rare type with multiple layers of column-shaped cells, primarily found in the male urethra. Since 'Stratified columnar' is a valid type of epithelium, it is NOT the correct answer for this question.

3. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?

• A. 60 cu cm
• B. 120 cu cm
• C. 150 cu cm
• D. 180 cu cm

Correct answer: C

Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.

4. When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), the resulting product is:

• A. Hydrogen gas and sodium chloride (NaCl)
• B. Chlorine gas and sodium oxide (Na2O)
• C. Sodium metal (Na) and water (H2O)
• D. No reaction occurs.

Correct answer: A

Rationale: This is a classic neutralization reaction, forming water and a salt (sodium chloride).

5. The phrase "a bold new world" is an example of

• A. Hyperbole
• B. Oxymoron
• C. Simile
• D. Metaphor

Correct answer: B

Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.

6. What mineral is essential for muscle function and nerve transmission?

• A. Calcium
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: A

Rationale: The correct answer is A: Calcium. Calcium is essential for muscle function and nerve transmission. Muscles require calcium to contract properly, and nerve cells use calcium ions to transmit signals throughout the body. Without an adequate amount of calcium, muscle cramps and nerve dysfunction can occur. Iron is important for oxygen transport in the blood, sodium and potassium are electrolytes important for fluid balance and nerve function, but they are not primarily responsible for muscle function and nerve transmission like calcium.
