My approach would be to read as many related news stories as I can about the topic. For example, I would click through any links in existing articles and read all the prior articles on the topic, so you can see how the story has developed over time (if appropriate).
Ideally, I would also read multiple opinion pieces/forum discussions/comments sections as I could to get a sense of what other people think about the topic. You might also want to look for podcast interviews and YouTube discussions on the topic. I would be thinking about what is my opinion on the topic throughout.
Finally, I'd practise summarising the topic aloud under timed conditions. I'd also try to answer questions like:
- Do I agree with how the author has written their article?
- Why do I find this story interesting?
- How does this link to other stories I have read?
- What are the future implications of this story?
