*ahem* Mushroom Stew doesn't have to be made in a crafting table, A mob spawner cage is black, a stronghold can have up to 3 eyes of ender and a repeater can go up to 4 ticks only. JESUS. I think you need to play some more Minecraft before making such a quiz...
You can build a house out of bedrock, you can place fences on top of each other, stone also has more items under 1 block ID, Horses exist, the Minecraft logo is a Dirt block or a Mojang sign... Do you want me to go on?
