Question 206·Hard·Rhetorical Synthesis
While researching a topic, a student has taken the following notes:
- Jupiter’s moon Europa has surface ice but might harbor an ocean beneath.
- The ocean’s salinity and depth remain unknown.
- NASA’s Europa Clipper mission, scheduled for launch in 2024, will carry ice-penetrating radar.
- The radar can map the thickness of Europa’s ice shell and detect potential water pockets.
- Understanding Europa’s ocean could inform the search for extraterrestrial life.
The student wants to emphasize the scientific significance of the Europa Clipper mission in a presentation to classmates. Which choice most effectively uses relevant information from the notes to accomplish this goal?
For rhetorical synthesis note questions, match your sentence to the stated goal. First, choose only information that is explicitly supported by the notes. Then, for a goal like “emphasize scientific significance,” include a broader impact statement (for example, informing the search for extraterrestrial life) while still naming the mission and what it will do.
Hints
Focus on the goal words in the question
Pay close attention to the phrase “emphasize the scientific significance.” The best option should communicate why the mission matters, not just what it will measure.
Find the note that explains why the research matters
Which note connects studying Europa’s ocean to a bigger scientific purpose (like the search for life)? The best sentence should include that connection.
Avoid statements that go beyond the notes
Be cautious with choices that claim the mission will determine the ocean’s salinity/depth. The notes say those properties are still unknown.
Step-by-step Explanation
Identify what the question is asking for
The student’s goal is to emphasize scientific significance. The best sentence should not only describe what Europa Clipper will do, but also explain why that work matters scientifically.
Pull the most relevant notes
Key note details to use are:
- The mission: NASA’s Europa Clipper, scheduled for launch in 2024
- The tool and what it does: ice-penetrating radar that can map ice thickness and detect potential water pockets
- The significance: understanding Europa’s ocean could inform the search for extraterrestrial life
Compare choices to the goal and the notes
Eliminate choices that either (a) only list technical capabilities without any broader importance, or (b) make claims the notes don’t support (for example, determining salinity/depth). Prefer a choice that accurately uses the radar details and links them to the search for extraterrestrial life.
Select the option that best emphasizes significance
The choice that combines accurate mission details (radar mapping ice and detecting potential water pockets) with the broader scientific purpose (informing the search for extraterrestrial life) is:
“Launching in 2024, NASA’s Europa Clipper will use ice-penetrating radar to map Europa’s ice shell and detect potential water pockets, findings that could inform the search for extraterrestrial life.”
