Explanation
Given the SDR, the report that can be generated is Booking Completion Rate. This is a measure of how many visitors who started an appointment booking completed it. It can be calculated by dividing event2 (Booking Complete) by event1 (Start Appointment Booking). The other reports, Time to Book an Appointment and Length of Appointments, cannot be generated with the given SDR, as they require additional variables or data sources.

Explanation
In Analysis Workspace, segments and time are two types of components that can be used to filter the scope of the report to a specific section of the website. Segments are subsets of data based on certain criteria, such as page name, traffic source, device type, etc. Time is a component that allows you to specify a date range or granularity for your report. Dimensions and standard metrics are not components that can be used to filter the scope of the report, but rather to break down or measure the data.
