Carbon is identified by the symbol "C" on the periodic table. Each carbon atom is made of six protons and six neutrons, giving it an atomic mass of twelve. The way the atoms are arranged gives carbon its form. Sometimes carbon is combined with other substances to create useful items, such as pencil lead. When mixed with oxygen, carbon forms carbon dioxide (CO2). People exhale carbon dioxide when they breathe, and carbon dioxide gives soda its bubbles.
The graphics add to the reading by serving which TWO of the following purposes?
- A. Reinforcing a real-world connection
- B. Summarizing key facts
- C. Providing a mnemonic device
- D. Contributing extra information
- E. Presenting an organizational framework
Correct Answer & Rationale
Correct Answer: A,D
Graphics enhance reading comprehension by reinforcing a real-world connection (A), helping readers relate content to familiar experiences. They also contribute extra information (D), offering visual context that deepens understanding. Option B, summarizing key facts, is typically the role of text rather than graphics. Option C, providing a mnemonic device, is more about memory aids than visual representation. Lastly, while option E, presenting an organizational framework, can be useful, it does not directly apply to the primary functions of graphics in enhancing reading. Thus, A and D best capture the essential roles of graphics.

The author supports the claim that satellites do not last forever through the use of which of the following?
- A. An anecdote about why satellites stop working when they do
- B. Examples of the ways satellites stop working over time
- C. A comparison of satellites to other common machines that stop working
- D. Suggestions for ways to keep satellites working over time
Correct Answer & Rationale
Correct Answer: C
The author effectively demonstrates that satellites do not last forever by comparing them to other common machines that also have limited lifespans. This comparison highlights the inevitability of wear and tear in technology, providing a relatable context for readers. Option A, an anecdote, may illustrate a specific instance but lacks the broader applicability needed to support the claim. Option B provides examples of satellite failures but does not frame them within a comparative context that strengthens the argument. Option D suggests preventive measures but does not address the inherent limitations of satellites, which is central to the claim.

Which of the following best describes a benefit of having students read both excerpts?
- A. Students can analyze the differences between a primary and a secondary source document.
- B. Students can compare the facts in the primary source to the emotions expressed in the secondary source.
- C. Students can understand different points of view when forming an opinion about an event.
- D. Students can learn to recognize whether sources are reliable.
Correct Answer & Rationale
Correct Answer: A
Analyzing both excerpts allows students to distinguish between primary and secondary sources, enhancing their understanding of historical context and perspective. Option B is misleading; while comparing facts and emotions is valuable, it does not specifically address the unique characteristics of primary versus secondary sources. Option C is also important, yet it focuses more on perspectives rather than the source types themselves. Option D, while relevant to evaluating reliability, does not emphasize the distinction between primary and secondary sources, which is central to the learning objective. Understanding these differences is crucial for critical analysis in historical studies.

When evaluating the student's writing, the teacher should highlight which of the following as a strength?
- A. A clear focus in paragraph 1
- B. Coherent development of ideas in paragraph 2
- C. A clear transition between the paragraphs
- D. Effective use of figurative language in both paragraphs
Correct Answer & Rationale
Correct Answer: B
Highlighting the coherent development of ideas in paragraph 2 emphasizes the student's ability to organize and elaborate on their thoughts effectively, which is crucial for persuasive and analytical writing. Option A, while important, only addresses focus in a single paragraph, lacking the depth of development seen in option B. Option C, though valuable, pertains to transitions, which are secondary to the overall idea development. Option D focuses on figurative language, which, while creative, may not contribute as significantly to the clarity and logic of the argument as the coherent development of ideas does.

Which of the following words would best be characterized as a Tier 3 vocabulary word?
- A. Family
- B. Gallop
- C. Peninsula
- D. Walk
Correct Answer & Rationale
Correct Answer: C
Tier 3 vocabulary words are specific, domain-related terms that are often used in particular contexts or subjects. "Peninsula" fits this category as it refers to a geographical feature, making it relevant in discussions about geography or earth sciences. In contrast, "Family" (A) is a common term used across various contexts, lacking the specificity of Tier 3 words. "Gallop" (B) and "Walk" (D) describe general actions and are more commonly used in everyday language, thus categorizing them as Tier 1 or Tier 2 vocabulary. Therefore, "Peninsula" is the most specialized term among the options.
