@MarianaMartins welcome to TCLA! Well done for making a post and engaging with the community 👏 👏 👏
For this question, if you haven't already, I'd suggest Google searching the biggest challenges for the legal sector and going through the recurring themes and topics. You can talk about any challenges, really, as long as you're able to show
- Why is it a challenge for the legal sector- what aspects of the sector is it impacting, how will it impact the business of a law firm etc.
- What makes it a challenge that law firms will have to prioritise in the short term i.e. the next year
- How should law firms react to the challenge so that they can overcome it and come out stronger
After looking at these factors, you'll see that writing about climate, sustainability or the SQE doesn't make the most sense as they present longer term challenges. You'll need to explore a bit deeper about what examples fit best here, but once you do this, writing your answer should flow naturally with the above structure!
