Question 34·Easy·Rhetorical Synthesis
While researching a topic, a student has taken the following notes:
- Induction cooktops use electromagnetic fields to heat compatible cookware directly.
- Because no gas is burned, induction cooktops do not produce combustion byproducts like nitrogen dioxide in the kitchen.
- Gas stoves can release nitrogen dioxide, which can irritate the lungs.
- Induction cooktops boil water faster and use energy more efficiently than gas stoves.
- Induction cooktops require magnetic cookware to operate.
The student wants to explain a health-related advantage of induction cooktops. Which choice most effectively uses relevant information from the notes to accomplish this goal?
For note-based rhetorical synthesis questions, start by underlining exactly what the question asks you to explain (for example, "health-related advantage," "environmental impact," or "cost benefit"). Then skim the notes and mark only the bullets that relate to that specific focus. Next, eliminate any answer choices that (1) use irrelevant notes, (2) leave out the key idea for the requested focus, or (3) add outside information not in the notes. The correct choice will be built from the relevant notes and will directly match the purpose stated in the question.
Hints
Focus on the task word in the question
Underline the phrase "health-related advantage" in the question. Eliminate any choices that do not clearly connect to health or effects on people’s bodies.
Locate health information in the notes
Look through the bullet points and find which ones mention things that can affect the lungs or breathing, not just how fast or efficiently something cooks.
Check which choices actually use that health information
Once you know which notes are health-related, choose the option that is built from those notes instead of from details about speed, technology, or cookware type.
Step-by-step Explanation
Identify what the question is asking for
The prompt says the student wants to explain a health-related advantage of induction cooktops. That means the correct answer must:
- Describe an advantage (a benefit), and
- Be about health, not just speed, efficiency, or how the stove works.
Find health-related information in the notes
Scan the notes for anything related to health or the body:
- One note says gas stoves can release nitrogen dioxide, which can irritate the lungs.
- Another note says that because no gas is burned, induction cooktops do not produce combustion byproducts like nitrogen dioxide. These two notes together point to a health advantage: avoiding a gas that can irritate lungs.
Match the correct idea to the answer choices
Now compare each choice to the health-focused idea from the notes:
- A talks about boiling water faster and using energy efficiently – that is about speed and efficiency, not health.
- C explains how induction cooktops work using electromagnetic fields – that is about the mechanism, not health.
- D states that induction cooktops require magnetic cookware – that is a requirement, not a health benefit.
- B explains that induction cooktops do not produce nitrogen dioxide and identifies it as a lung irritant associated with gas stoves, clearly stating a health-related advantage.
Therefore, the correct answer is: B) Because they do not burn gas, induction cooktops do not produce nitrogen dioxide in the kitchen, a lung irritant associated with gas stoves.
