I want to know how should I answer this question? what would be the structure of the essay (essay plan)?

Question: Critically discuss the following claim:

'Law is necessarily moral. It becomes moral any time content is injected into otherwise hollow concepts, like reasonableness and the reasonable person. Hence legal positivism is, necessarily, false.'

Markers note: what relationship does law have to other normative systems, and most importantly, morality?
