Answer: 
Confirm?
Correct:
It helps you troubleshoot errors in your environment by displaying all of the information about your current SharePoint web requests. It includes the web addresses of the SharePoint sites you’re visiting, the results of those web requests, and even the ULS logging entries created that are related to your activities.
In terms of the ULS log entries, you’ll get to quickly view all ULS entries that are related to your current web requests, regardless of what server those entries actually live on. Since ULS logs are kept on each server in your farm, but each server keeps only the entries that are created by that server, having the overall view of the ULS entries that are related to the actions you’re performing is a really handy benefit.
