Exercise 1

1. For the sentence below, identify the position, the reason, and the reason's basis, and map them in the appropriate kind of boxes:

NASA is an equal opportunity employer, since they employ female astronauts, for instance Roberta Bondar and Mae Jemison.

Drag and drop sections of the above text onto the workspace to proceed.  This works with any version of Rationale.



  • Look for indicator words to provide clues about argument structure
  • Identify and map the claims
  • Identify the basis which supports the reason
  • Select the proper basis icon and type in the necessary details

2. Check your work against the model.
