ACT (Enhanced)ReadingMedium
A research paper analyzes the impact of climate change on polar bear populations. It cites multiple long-term studies detailing declines in sea ice extent and thickness, directly linking these changes to reduced hunting success for polar bears and subsequent declines in their body condition and reproductive rates. The paper concludes by stating that 'without significant global action to mitigate greenhouse gas emissions, the long-term survival of polar bears is severely threatened.' What is the author's primary purpose in writing this paper?
- ATo inform readers about the various species of polar bears.
- BTo compare the hunting strategies of different polar bear populations.
- CTo entertain readers with stories of polar bear resilience.
- DTo persuade readers of the urgency of addressing climate change for conservation.
Show answer & explanationAnswer & explanation
Correct answer: D. To persuade readers of the urgency of addressing climate change for conservation.
The paper presents evidence of climate change's negative impact on polar bears and concludes with a call to action ('without significant global action... severely threatened'). This structure, moving from evidence to a dire warning and implied necessity for change, indicates a primary purpose of persuasion.
Why the other options are wrong
- A. While information is provided, the focus is on the threat to *all* polar bears due to climate change, not a general overview of species.
- B. The text focuses on the *impact* on hunting success, not a comparison of hunting strategies.
- C. The tone and content are scientific and urgent, not entertaining.
Author's Purpose (Persuade)
The author's intention to convince the reader to agree with a particular viewpoint, take a specific action, or change their beliefs about a topic.
- Often uses emotional appeals, logical arguments, and calls to action.
- May present evidence selectively to support a claim.
- Distinguishable from merely informing or entertaining.
Memory trick: P.I.E.: Persuade, Inform, Entertain – know the author's aim, play the game.
