The questions Miriam should ask to evaluate whether she has successfully followed the procedure for conducting research described in <em>Don MacLeod's How to Find Out Anything</em> are:
Do I have all the information that I need?
Have I found an answer to each of my questions?
By answering these two questions, she would know for sure if she reached the objective or not because in a successful research those items, having all the information and having all the answers, are indispensable.
The other questions can be done or not, and it will not define the success of the investigation.
