(a) In the Seeheim model: Treating the Application Interface model and Application together, there are three main layers:

(i) presentation/lexical
(ii) dialogue/syntactic
(iii) application/semantic

For each of these three layers list at least two different items of the description of the nuclear reactor control panel that is relevant to the level (that is at least six items in total, two for each level)

(b) There are no items in the description that relate to the switch (rapid feedback) part of the Seeheim model. Why do you think this is the case?
