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.

When discussing strategies for delivering effective oral presentations, a teacher should focus on how speaking slowly promotes which of the following?
- A. Clear articulation of words
- B. Audibility for the audience
- C. Appropriate emphasis of key ideas
- D. Interest in the topic for the audience
Correct Answer & Rationale
Correct Answer: A
Speaking slowly enhances clear articulation of words, allowing the speaker to pronounce each syllable distinctly, which aids in comprehension. This clarity is crucial for the audience to grasp the message being conveyed. While audibility (Option B) is important, it primarily relates to volume rather than the speed of speech. Similarly, appropriate emphasis of key ideas (Option C) can be achieved through varying tone and pace, but it does not directly stem from speaking slowly. Lastly, interest in the topic for the audience (Option D) depends more on the content and delivery style rather than the speed of speech.

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.

During an oral presentation, which of the following strategies will best help a speaker facilitate audience comprehension of the material presented?
- A. Varying vocal volume
- B. Articulating words clearly
- C. Wearing proper attire
- D. Using hand gestures
Correct Answer & Rationale
Correct Answer: B
Articulating words clearly directly enhances audience understanding, ensuring that key points are communicated effectively. This clarity is essential for comprehension, particularly in complex topics. Varying vocal volume (A) can engage the audience but may not significantly aid in comprehension if the words are not articulated clearly. Wearing proper attire (C) contributes to professionalism but does not impact the audience's understanding of the material. Using hand gestures (D) can support engagement and emphasize points but, without clear articulation, may lead to confusion rather than clarity.

Which of the following statements is true?
- A. In sentence 1, the word "knew" is functioning as an adverb.
- B. In sentence 1, the word "knew" is functioning as a verb.
- C. In sentence 3, the word "really" is functioning as an adjective.
- D. In sentence 3, the word "really" is functioning as a noun.
Correct Answer & Rationale
Correct Answer: B
In sentence 1, "knew" serves as a verb, indicating an action or state of being related to knowledge. This aligns with its grammatical role as a past tense verb, which expresses what someone understood or was aware of. Option A is incorrect as "knew" cannot function as an adverb; adverbs modify verbs, adjectives, or other adverbs, not serve as the main verb in a sentence. Option C misinterprets "really," which typically acts as an adverb to modify verbs or adjectives, not as an adjective itself. Option D is also incorrect since "really" does not function as a noun; it does not represent a person, place, thing, or idea.
