Reverse sort by date in FAQ block questions - latest questions by date first?

Question

XML

Hello.
Tell me how to do reverse sorting by date when displaying questions and answers in the FAQ
section This section is responsible for the output. Displays old questions first, and new ones on the last pages.
Thanks in advance.
