In the context of inferring, the term micro-level refers to the inferring that takes place between the word and sentence level. For example, if when reading Hansel and Gretel you imagine the character are German, based on their names, this would be a backward micro-elaborative inference.
This inference is backward because it it involves an inference about something that has been read - the names. It is micro because is occurs at the word level. It is elaborative because it is not necessary to suppose that the children are German in order to understand the story.
Prompts are found in each of the supersets.
