First, export your shapefile to a .KML or .KMZ file.
KML stands for Keyhole Markup Language. .KML files are file formats used to display geographic data in an Earth browser such as Google Earth. You will need to use a shapefile to add a map boundary to this question type. This can be done in software such as Google Earth or ArcGIS.
Next, from your project page, click the green "add question" button:
From this list of question types, select "Map Response"

In the pop-up field, enter a prompt or question.
From the question creation box, add your KML or KMZ file.
Your shapefile will appear as a layer on top of the map.
