Question 203·Medium·Rhetorical Synthesis
While researching a topic, a student has taken the following notes:
- In 2021, researchers at the University of Melbourne examined the relationship between exposure to urban green spaces and mental health among 6,000 city residents.
- The researchers used satellite imagery and participant questionnaires to estimate each person’s weekly exposure to green space.
- Residents who spent at least 30 minutes per day in green spaces exhibited 7% lower levels of the stress hormone cortisol than residents who spent less time.
- Higher exposure to green space was also associated with a 12% lower incidence of mild depression.
The student wants to summarize the study. Which choice most effectively uses relevant information from the notes to accomplish this goal?
For questions asking you to summarize research from notes, first quickly identify the core: who was studied, what variable or relationship was examined, and what the main findings were. Label other details (methods, exact numbers) as secondary. Then scan the answer choices and eliminate any that only mention method, only one small result, or just the goal without reporting conclusions. Choose the sentence that captures the overall relationship and key outcomes in a single, clear statement using multiple pieces of the most important information from the notes.
Hints
Decide what a one-sentence summary should include
Ask yourself: If I had to explain this entire study in one sentence to a friend, what are the MOST important points I would mention? Focus on who was studied and what main relationship or conclusion was found.
Separate main findings from details
Look back at the notes and mark which bullets tell you the general relationship between green space exposure and mental health, and which bullets describe technical details (like tools used or exact percentages). A summary should focus on the general relationship and main outcomes.
Check each option for completeness
For each answer choice, ask: Does this sentence stand on its own as a summary of the whole study, or does it only describe methods, a single statistic, or just the goal? Eliminate any choice that leaves out major parts of what the researchers found.
Step-by-step Explanation
Understand what a good summary must do
The question asks for a sentence that will "summarize the study." A good summary of research in one sentence should:
- Identify the study and participants (who/when/where, if relevant).
- Capture the main purpose or relationship studied.
- Include the key overall findings.
It should NOT get lost in technical details (like specific tools or exact percentages) unless they are essential to the main point.
Pull out the central ideas from the notes
Look at the four bullet points and separate main ideas from details:
Main ideas:
- In 2021, University of Melbourne researchers studied 6,000 city residents.
- They examined the relationship between exposure to urban green spaces and mental health.
- Spending at least 30 minutes per day in green spaces was associated with lower stress.
- Higher exposure to green space was linked to a lower incidence of mild depression.
Details (supporting, not required for a one-sentence summary):
- The specific tools used to measure exposure (satellite imagery, questionnaires).
- The exact numbers 7% and 12% (exact effect sizes), unless the question specifically asks for them.
Eliminate answers that only focus on method or one detail
Now compare each option to those main ideas.
- One option talks only about how the researchers estimated time in green spaces (satellite images and questionnaires). That focuses on method, not the overall findings.
- Another option mentions just one numerical result about cortisol levels and says nothing about depression or the broader connection to mental health.
Neither of these can be a full summary of the study, because each mentions only a slice of the information.
Eliminate answers that lack the study’s main findings
Look at the remaining choice that describes the researchers’ goal and that they examined residents’ routines. While this gives some context (who did the study and what they wanted to find out), it does not state what they actually found about stress or depression.
A summary of a study must include the key result or conclusion, not just the purpose and procedure, so this option is incomplete as a summary.
Choose the option that combines context and main results
The correct choice is the one that:
- Identifies the study: a 2021 University of Melbourne study of 6,000 city residents.
- States the key exposure: spending at least 30 minutes a day in urban green spaces.
- Reports the main mental health outcomes together: lower stress levels and reduced mild depression.
This matches and condenses the central points of the notes into one clear sentence: "A 2021 University of Melbourne study of 6,000 city residents linked spending at least 30 minutes a day in urban green spaces with lower stress levels and reduced mild depression."
