I also have some notes on how to tackle this question from Simranjeet Kaur Mann's Instagram. I find her advice really helpful. Use the description below to make more sense of the picture attached.
BLUE- Here I describe the news story briefly - it's important to keep this brief to set the scene. Law firms want to know more about your personal take on the news story and how it relates to them, rather than a longwinded description of what's happened.
Yellow- go straight into answering the next part of the question - note I don't provide a vague reason for why this news story interested me; I provide two links to my personal experiences to exemplify my attraction to this story.
Green - provide a more in-depth analysis of the news story, together with my personal opinion and a further quotation from a Judge. This highlights I've gone out of my way to research this topic further, thus showing a genuine interest in the article.
Orange- Here I focus on the last part of the question. Admittedly, I could have maybe mentioned more. However, note what I did write was specifically targeted at the firm I was applying for and showed dedicated research, rather than vague reasoning.
