Purpose of the introductory context

I wanted to highlight this one part in upper left corner. It says

Impetus: What caused these sources to come together in this way? And for what reasons? This is partly the purpose of the introduction. But you should be aware of this for later.

This is context, context that explains the arrangement of the results section. But it is a different sort of context from our normal, everyday context. The same goes for the discussion. The purpose of the discussion section is to ask whether and how the results fit into the field, which is another context. There are, then, at least three different types of context. We'll worry about this more after spring break.
