1. Which of the following values is the greatest?

• A. 2/11
• B. 5.4
• C. 13/3
• D. 6.25

Correct answer: D

Rationale: To determine the greatest value among the given options, convert the fractions to decimal form. 2/11 is approximately 0.1818, 5.4 is a decimal itself, 13/3 is approximately 4.333, and 6.25 is a decimal. Comparing these values, 6.25 is the largest among them. Therefore, option D, 6.25, is the correct answer. Choices A, B, and C are smaller values compared to 6.25, making them incorrect answers.

2. What is a recommended first step when generating ideas for a group presentation?

• A. Interview sources for your presentation.
• B. Brainstorm interesting topics and ideas.
• C. Develop an organized outline of the topic.
• D. Cite the sources in your presentation.

Correct answer: B

Rationale: The correct answer is B: Brainstorm interesting topics and ideas. Brainstorming is an essential initial step in the creative process of generating ideas for a group presentation. It allows team members to freely share thoughts, explore various angles, and come up with innovative concepts. Choice A, interviewing sources, typically comes after brainstorming to gather information. Choice C, developing an organized outline, usually follows brainstorming to structure the presentation content. Choice D, citing sources, is important but is not the first step in the idea generation process.

3. Which sentence uses the word 'literally' correctly?

• A. I literally died laughing at that joke.
• B. He literally climbed a mountain of paperwork.
• C. Her eyes were literally sparkling with excitement.
• D. The house was literally haunted by ghosts.

Correct answer: B

Rationale: The correct answer is B because it uses 'literally' to emphasize the magnitude of work, not to exaggerate a simple action. In this sentence, 'literally' is used to convey the idea that the person climbed a significant amount of paperwork, highlighting the challenging and overwhelming nature of the task. Choices A, C, and D use 'literally' inappropriately by exaggerating or using the word in a non-literal sense. In choice A, 'died laughing' is a common expression and not meant to be taken literally. Choice C describes a figurative expression, not a literal one. Choice D involves the supernatural, which is not a literal occurrence.

4. What is hydroxyapatite?

• A. A mixture of minerals such as calcium and phosphorus that strengthen the collagen matrix of bone.
• B. The structural unit of a bone that runs the length of the bone.
• C. The covering of bones at the point of articulation to prevent grinding.
• D. The lightest portion of a long bone and concentrated at the ends.

Correct answer: A

Rationale: Hydroxyapatite is a mineral compound composed of calcium and phosphorus that plays a crucial role in strengthening the collagen matrix of bones, contributing to their structural integrity and hardness. It is a key component of bone tissue and provides the mineralization necessary for bone strength and density. Choice B is incorrect because the structural unit of a bone is the osteon or Haversian system, not hydroxyapatite. Choice C is incorrect as it describes cartilage, not hydroxyapatite. Choice D is incorrect as it refers to the epiphysis, which is not synonymous with hydroxyapatite.

5. How can you distinguish between these three types of graphs - scatterplots: Quadratic, Exponential, Linear?

• A. Linear: straight line; Quadratic: U-shape; Exponential: rises or falls quickly in one direction
• B. Linear: curved line; Quadratic: straight line; Exponential: horizontal line
• C. Linear: zigzag line; Quadratic: U-shape; Exponential: flat line
• D. Linear: straight line; Quadratic: W-shape; Exponential: vertical line

Correct answer: A

Rationale: To differentiate between the three types of graphs - scatterplots, a linear graph will display a straight line, a quadratic graph will have a U-shape, and an exponential graph will show a rapid rise or fall in one direction. Choice B is incorrect because linear graphs are represented by straight lines, not curved lines. Choice C is incorrect as linear graphs do not exhibit zigzag patterns, and exponential graphs do not typically result in flat lines. Choice D is incorrect because quadratic graphs form a U-shape, not a W-shape, and exponential graphs do not represent vertical lines.
