Solution:

#### 1. What color is blue?
- Answer: Blue is a primary color in the visible spectrum, characterized by short wavelengths of light. It is one of the colors humans can perceive distinctly.

#### 2. Why is it so rare?
- Answer: Blue is rare in nature because very few natural objects produce or reflect blue pigments. Most instances of blue in nature (e.g., the sky, water) are due to scattering or refraction of light rather than inherent blue pigmentation. This rarity makes blue stand out as a unique and special color.

#### 3. What do you notice about the first two words? Why do you think they are set out this way?
- Observation: The first two words, "Fast fact-finding," are bolded and centered at the top of the passage.
- Reasoning: These words are likely set out this way to indicate the purpose of the activity. They signal to the reader that the task involves quickly identifying key facts from the passage. This formatting helps draw attention to the instructional goal.

#### 4. What kind of sentences introduce the passage?
- Analysis: The passage begins with a declarative sentence: "Have you ever wondered why the color blue is something we take for granted?" This sentence introduces the topic and engages the reader by posing a question.
- Answer: The passage is introduced with a declarative sentence that poses a thought-provoking question.

#### 5. What does it do?
- Contextual Clue: The phrase "What does it do?" likely refers to the color blue or the concept being discussed.
- Answer: Blue is often associated with calmness, stability, and trust. In human culture, it is used symbolically to convey these qualities. Additionally, blue is frequently used in art, design, and technology to evoke feelings of reliability and professionalism.
