Praxis 5001 Practice Exams Practice Question
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 (COâ‚‚). 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
Correct Answer: A
Rationale: Graphics in the text serve to reinforce a real-world connection by illustrating how carbon is involved in everyday items like pencil lead and soda. This visual representation helps students relate the concept of carbon to familiar experiences, enhancing understanding.
Option B, summarizing key facts, is incorrect as the graphics do not condense information but rather complement it. Option C, providing a mnemonic device, is not applicable since the graphics do not aid in memory retention through association. Option D, contributing extra information, is misleading; while graphics may add context, their primary role here is connection, not additional facts. Option E, giving an organizational framework, does not fit as the graphics do not structure information but rather enhance engagement.
