Opening .pub files using libre office

My son has started getting his homework online, he downloaded a .pub file that needed to be printed off for revision, as he doesn’t have microsoft on his lap top he opened it using Libre office 4.0, this only allowd the header text to be visible & not the main part of the homework, any ideas, thank you
