1. You need to paint a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m. Considering only the interior walls and floor (not the top), how much paint do you need (assume one can of paint covers 10 sq m)?

• A. 56 sq m
• B. 72 sq m
• C. 88 sq m
• D. 104 sq m

Correct answer: C

Rationale: Calculate the areas of each wall and the floor, sum them up, and subtract the area of the water surface (top). Divide the final area by the coverage area per can to determine the number of cans needed.

2. Which word completes the sentence "He was ____ by the unexpected turn of events."

• A. elated (joyful)
• B. bewildered (confused)
• C. vindicated (justified)
• D. apathetic (uninterested)

Correct answer: B

Rationale: "Bewildered" best describes the confusion caused by the unexpected events.

3. Which of the following factors would increase the solubility of a gas in a liquid?

• A. Decreasing temperature
• B. Increasing pressure
• C. Decreasing surface area
• D. Increasing particle size

Correct answer: b

Rationale: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The other choices would typically decrease solubility.

4. What is a mutation?

• A. A change in the DNA sequence
• B. A type of protein
• C. A normal part of the DNA replication process
• D. A harmless variation in DNA

Correct answer: A

Rationale: Rationale: A mutation is defined as a change in the DNA sequence. Mutations can occur due to various factors such as errors during DNA replication, exposure to mutagens (e.g., chemicals, radiation), or spontaneous changes. These changes can result in alterations to the genetic information carried by an organism, which can have different effects ranging from harmless variations to causing genetic disorders or diseases. Mutations are a fundamental aspect of genetic diversity and evolution. Options B, C, and D do not accurately describe what a mutation is.

5. Which of the following statements is true regarding a supersaturated solution?

• A. It is unstable and tends to crystallize
• B. It contains less solute than it could dissolve
• C. It has a lower concentration than a saturated solution
• D. It is rarely encountered in everyday solutions

Correct answer: a

Rationale: Supersaturated solutions are unstable and tend to crystallize if disturbed. The other choices do not accurately describe supersaturated solutions.

6. Which sentence uses strong verbs to create a more vivid image?

• A. The car moved slowly down the street.
• B. The car drove sluggishly down the road.
• C. The car inched down the avenue.
• D. The car traveled down the thoroughfare.

Correct answer: C

Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."
