Digital SATReading and Writing: Craft and StructureMedium
An environmental scientist is writing a report on the effects of climate change on polar bear populations. The report's conclusion section needs to summarize the findings and emphasize the urgency of mitigation efforts. To achieve this purpose, which of the following would be the most effective concluding statement?
- AWhile polar bear populations face challenges, their resilience in adapting to changing environments should not be underestimated.
- BThe data unequivocally demonstrates that declining sea ice directly impacts polar bear survival, necessitating immediate and concerted global action.
- CFurther research is required to fully understand the long-term implications of climate change on Arctic ecosystems.
- DPolar bears, as apex predators, play a crucial role in maintaining the balance of the Arctic food web.
Show answer & explanationAnswer & explanation
Correct answer: B. The data unequivocally demonstrates that declining sea ice directly impacts polar bear survival, necessitating immediate and concerted global action.
The conclusion needs to 'summarize findings' and 'emphasize urgency.' Option B directly states a clear finding ('data unequivocally demonstrates') and calls for 'immediate and concerted global action,' aligning perfectly with both requirements.
Why the other options are wrong
- A. This statement downplays urgency by focusing on resilience, contrary to the report's purpose.
- C. While true, calling for 'further research' does not convey the required sense of 'urgency' for 'mitigation efforts.'
- D. This is a factual statement about polar bears' role but does not summarize findings or emphasize the urgency of mitigation related to climate change.
Conclusion Purpose
The final section of a text that restates the thesis, summarizes main points, and offers a final thought or call to action.
- Provides a sense of closure.
- Reinforces the main argument.
- Can suggest implications or future directions.
Memory trick: Close the door, review the path, leave a lasting thought.
