Final answer:
The output method for estimating progress may ignore typos or irrelevant information, leading to inaccurate results.
Step-by-step explanation:
A shortcoming of the output method for estimating progress toward completion is that it may ignore any typos or irrelevant parts of the questions being asked. This can lead to inaccurate results and misrepresentation of the actual progress. For example, if a student makes multiple typos or includes irrelevant information in their response, the output method may overlook these errors and provide a false indication of completion.
