Based on the code below answer the following questions (python):

• Show the source line that constructs the query we wish to send to the Knowledge Graph API.

• Show the source line that then executes the query and saves the response. What is the name of the method that sends the query to the Knowledge Graph API?

• What is the Python data type that is used to represent the formatted message?
