Q. How do I save selected pages from a PDF document?

You can extract the pages you want using Adobe Acrobat Pro.  To do this, be sure the Page Thumbnail view is open.  If it isn't, you can select it by clicking the icon that looks like multiple pages on the far left hand side of the screen.  Once the thumbnail view is available, right click on one of the thumbnail pages.  Select "Extract Pages."  You can then select a range of pages to be extracted.  The pages you select will by copied or moved to a new file.
