As I see it, the Grab Bags can be the hardest to complete but also count for 8 correctly answered questions towards the 50 question and title achievements so this guide can be used for most not just this achievement.
Here are the answers to all the Grab Bags I encountered completing this game.
*Sorry I do not have the categories specified for which each comes from.
*Some question titles may be vaguely accurate with rough misspelled answers but they are all easy enough to figure out with the in game options as reference. example: answer could be "How the Grinch Stole Christmas" while my answer given may only be "Grinch"
