Question 207·Medium·Rhetorical Synthesis
While preparing a class presentation, a student has collected the following facts about NASA's Perseverance rover:
- Perseverance launched in July 2020 and landed in Jezero Crater on February 18, 2021.
- The rover is equipped with a drill that stores rock cores for a future sample-return mission.
- Its primary science goal is to search for evidence of past microbial life on Mars.
- Perseverance carried the helicopter Ingenuity, which completed the first powered flight on another planet.
The student wants to open the presentation with a sentence that emphasizes the rover’s scientific goals.
Which choice most effectively uses relevant information from the notes to accomplish this purpose?
For rhetorical synthesis questions with notes, first underline the purpose in the question (here, emphasizing scientific goals). Then identify which notes directly match that purpose. As you scan the choices, eliminate options that focus on less relevant details (dates, locations, or side achievements) or add unrelated information, and choose the sentence that most directly and completely fulfills the stated purpose using the notes.
Hints
Focus on the stated purpose
The question says the student wants to emphasize the rover’s scientific goals. Which notes explain what Perseverance is trying to find or do on Mars?
Separate goals from background details
Which bullet points describe the rover’s objectives (its investigation and collection work) rather than dates, locations, or Ingenuity?
Check that the sentence is built from the goal notes
Eliminate choices that mainly repeat background details (launch/landing/Ingenuity). Pick the option that clearly states Perseverance’s mission objectives from the notes.
Step-by-step Explanation
Identify the purpose
The student wants an opening sentence that emphasizes Perseverance’s scientific goals. So the best option should focus on what the rover is trying to discover and collect, not primarily on dates or on Ingenuity’s achievement.
Pull the goal-related notes
From the notes, the mission’s key science goals are:
- searching for evidence of past microbial life on Mars
- using a drill to store rock cores for a future sample-return mission
A strong opening should center these ideas.
Eliminate choices that don’t foreground the goals
Choices that mainly emphasize launch/landing details or Ingenuity’s flight do not highlight Perseverance’s scientific goals. The best choice will directly mention the life-search objective and the sample-caching objective.
Choose the option that best matches the purpose
The option that most effectively emphasizes Perseverance’s scientific goals is:
NASA's Perseverance rover is searching for evidence of past microbial life on Mars and storing rock cores for a future sample-return mission.
