Question Alteration

When writing my essay I've realised that the question I've been trying to answer is actually in two parts, and so my research and answers are still sounding too general. Trying to answer two questions in one is meaning that the essay isn't achieving much depth and I think I'm missing out on creating a more focused piece of writing.

How are children still being targeted by junk food marketing in the UK, despite regulations being introduced in order to limit this, and what more could potentially be done to reverse the current childhood obesity crisis?

Changed to :

In the current childhood obesity crisis, how have food companies, despite regulations, adapted their marketing strategies to continue to sell junk food to children?

This is more focused and I think my essay writing will be more successful if I'm answering this question only in depth, backing up with quotes and research.
