Hi, I would interpret this to scatter 'why commercial law' throughout the cover letter.
For example, when talking about 'why
NRF' you could mention here why commercial law and then specifically why commercial law at
NRF.
'What excites you about our programme' also has scope for you to sprinkle in why commercial law. Why specifically does your interest in commercial law excite you about what
NRF offer on their programme and how you will use that passion and understanding of a commercial solicitor in the position you are applying to.
Finally, in terms of skills matching values, this could be a great opportunity to highlight your commercial awareness. Not simply stating you have commercial awareness but how using that skill of commercial awareness and your interest in commercial law fits with the firms values.
I know you will have limited words, however, this is the approach I would attempt to take. I have never applied to
NRF so someone else might have a better insight, but I think the fact that they have dropped the 'why commercial law' question means they will be looking for you to indicate through the other questions why commercial law and also indicate your commercial awareness of the firm and also their clients etc.
