1. Shawna buys 5 gallons of paint. If she uses 2/5 of it on the first day, how much paint does she have left?

• A. 3 gallons
• B. 2 gallons
• C. 1 gallon
• D. 0.5 gallons

Correct answer: A

Rationale: To find out how much paint Shawna uses on the first day, calculate 2/5 * 5 = 2 gallons. Subtracting the amount used from the total amount gives us 5 - 2 = 3 gallons remaining. Therefore, Shawna has 3 gallons of paint left after using 2 gallons on the first day. Choice A is correct. Choices B, C, and D are incorrect because she has more paint left than the options presented.

2. What does the phrase 'think outside the box' encourage individuals to do?

• A. Follow established procedures.
• B. Be creative and find new solutions.
• C. Accept traditional ideas.
• D. Avoid making mistakes.

Correct answer: B

Rationale: The expression 'think outside the box' promotes creativity and innovation by urging individuals to consider unconventional and original ideas to solve problems or tasks, rather than sticking to conventional or traditional methods. This phrase emphasizes the importance of exploring new perspectives and solutions that are not limited by existing boundaries or norms. Choice A is incorrect because 'think outside the box' encourages individuals to break away from established procedures. Choice C is incorrect as the phrase contradicts accepting traditional ideas. Choice D is incorrect because 'think outside the box' does not focus on avoiding mistakes but rather on exploring new and innovative solutions.

3. How does the amplitude of a wave relate to its intensity or loudness?

• A. They are inversely proportional.
• B. They are directly proportional.
• C. They have no relationship.
• D. Amplitude affects frequency, not intensity.

Correct answer: B

Rationale: The amplitude of a wave is directly related to its intensity or loudness. In general, the larger the amplitude of a wave, the greater its intensity or loudness. This relationship is due to the fact that the amplitude of a wave represents the maximum displacement of particles in the medium from their rest position. The greater the displacement, the more energy the wave carries, leading to higher intensity or louder sound. Choice A is incorrect because the relationship between amplitude and intensity is direct, not inverse. Choice C is incorrect as there is a clear relationship between amplitude and intensity. Choice D is incorrect as amplitude primarily affects intensity or loudness, not frequency.

4. Which term refers to the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: C

Rationale: Density is the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and volume is the amount of space an object occupies. In this context, density is the correct term for expressing the measure of mass per unit volume, making it the most appropriate choice among the options provided.

5. What are the small, finger-like projections in the small intestines called?

• A. Cilia
• B. Rugae
• C. Trachea
• D. Villi

Correct answer: D

Rationale: The correct answer is D: Villi. Villi are small, finger-like projections in the small intestine that increase the surface area for absorption, aiding in the absorption of nutrients. Cilia (Choice A) are tiny hair-like structures found in various parts of the body but are not present in the small intestine. Rugae (Choice B) are folds in the mucosa of the stomach that allow for its expansion during digestion. The trachea (Choice C) is part of the respiratory system, responsible for carrying air to and from the lungs, and is not related to the small intestine.
