There wil be a full explanation of this in your confuser and text books. I would strongly advise brushing up on that first.
Throughout the majority of the UK the Transition Altitude is set at 3000ft (QNH). The Transition Layer is 150ft and then you move into the Transition Level.
I learnt it by thinking: -
Transition
Altitude = Vertical Position reported as
Altitude.
Transition Layer = 150ft of space in between.
Transition
Level = Vertical Position reported as Flight
Level
Hope this helps but you really do need to read the explanation fully in the back of your confuser mate. It is basically a roundabout way of being asked to define the order of the three components. I understand what you mean though, the CAA papers are a pain in the arse to read. The exams would be half the length of time if someone with half a brain actually wrote the exams in a legible format that gets to the point rather than leading yuou down the garden path to get to the question.
