If I delete a page, does it delete all the questions on the page?

If I delete a page, does it delete all the questions on the page or just the page break?

If you delete a page, all of the related questions will remain and they will be moved to the previous page. All questions on the first page will be moved to the next page once you delete the first page. 

So, if you delete a page, you will just delete the page break.
