The discussion technique that Jennifer uses most clearly in this conversation is, challenging assumptions.
When we want to give a discussion a different approach, we use this technique through What if... questions, it is necessary to present another alternative to respond to things that we already established.
The other techniques are very different from this one, promoting participation would be mostly used by a moderator not a regular participant in the conversation, MAking an objective is to land the discussion into something real, and Asking for rhetorical questions does expect any kind of answer which we do have in here, therefore the other three options are incorrect.
So that the audience isn’t confused on the authors purpose. With a smaller area it leaves not much confusion and allows the reader to know what he/her is reading.
I believe it's have but don't take my word for it :)
A functional document, also known as functional specification, is a document that specifies the function that a system must perform, mostly regarded in systems engineering and software development. It typically describes what the system needs by the user, including the requested properties of inputs and outputs. It is somewhat similar to a matching requirements document.
