Answer:
I am easy to waste and unstoppable. What am I?
I have no voice but I can teach you all there is to know. I have spines and hinges but I am not a door. Once I’ve told you all I cannot tell you more.
I have a head but never weeps. I have a bed but never sleeps. I can run but never walks. I have a bank but no money. What am I?
I am one small little piece of paper yet sometimes hold lots of value. I am all you need to get in to big events but will cost you. I am an important part of travel. And if lost you're not coming.
I am an odd number. Take away a letter and I become even. What number am I?
I have two bodies joined together as one. When standing still I run and run.
