1. What is the relationship between mass and weight on Earth's surface?

• A. Mass and weight are equal
• B. Mass is greater than weight
• C. Weight is greater than mass
• D. Mass and weight are not related

Correct answer: a

Rationale: On Earth's surface, mass and weight are directly proportional but not equal, as weight is the force due to gravity acting on an object's mass.

2. If the mass of an object remains constant and its velocity doubles, how does its momentum change?

• A. Momentum doubles
• B. Momentum halves
• C. Momentum quadruples
• D. Momentum remains the same

Correct answer: a

Rationale: Momentum is directly proportional to velocity when mass is constant.

3. Which condition is characterized by inflammation of the inner lining of the stomach?

• A. Gastroesophageal reflux disease (GERD)
• B. Diverticulitis
• C. Ulcerative colitis
• D. Gastritis

Correct answer: D

Rationale: The correct answer is D, gastritis. Gastritis refers to the inflammation of the inner lining of the stomach, which can be caused by various factors such as excessive alcohol consumption, prolonged use of NSAIDs, or bacterial infections like H. pylori. Gastroesophageal reflux disease (GERD) is characterized by the backflow of stomach acid into the esophagus, not inflammation of the stomach lining. Diverticulitis is inflammation of small pouches that can develop in the colon, while ulcerative colitis is inflammation in the large intestine. Therefore, gastritis best fits the description of inflammation in the inner lining of the stomach.

4. Which of the following questions is NOT appropriate for scientific investigation?

• A. How can we reduce greenhouse gas emissions?
• B. Is there intelligent life beyond Earth?
• C. What is the meaning of life?
• D. Does free will exist?

Correct answer: C

Rationale: Science deals with observable, measurable phenomena using evidence-based methods. Questions about subjective experiences and abstract concepts like meaning fall outside the realm of scientific inquiry.

5. What is the term for the chemical reaction that involves the loss of electrons?

• A. Reduction
• B. Oxidation
• C. Neutralization
• D. Precipitation

Correct answer: b

Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.

6. A playground fence has a rectangular section (5m by 3m) attached to a semicircular section with a radius of 2m. What is the total perimeter?

• A. 13m
• B. 16m
• C. 19m
• D. 22m

Correct answer: D

Rationale: Calculate the semicircle perimeter (π * radius) and add it to the rectangular perimeter: perimeter = π * radius + 2 (length + width) ≈ 3.14 * 2m + 2 (5m + 3m) ≈ 6.28m + 16m ≈ 22.28m ≈ 22m (rounded).
