B2 CATs

I am really struggling with my biology b2 controlled assessments (edexcel)
it is on how does changing the concentration of food colouring affect the distance in which the food colouring has diffused? Can somebody please give me an exemplar A* or just tips and advice on how to complete it?

Thanks
