1. The link must not work for you. Works fine for me.
2. After being raised on a chicken farm and forcibly bred to generate the perfect "egg", Harold decided to run away. After a few years he met up with another hen named Carol, and she and he were able to live happy life, until the same farmer who had imprisoned him for so many years found him, and killed his wife. Heartbroken, Harold went to the bar that night and got drunk. Eventually he caused so much trouble that he was kicked out, and Harold stumbled towards the nearest, busy intersection. Feeling as if there was no way he could possibly have a happy ending, the chicken closed his eyes and crossed the road. Every step he took he began to feel more and more at peace. Then, Harold opened his eyes. He realized that he was now on the other side of the road. He broke down and began to cry. END
3. Write the command block command to give the nearest player a diamond sword with sharpness V, fire aspect II, and knockback II named "Excalibur"(so original i know) that also has the lore "An amazing sword.".
/give @p minecraft:diamond_sword 1 0 {display:{Name:"Excalibur",Lore:[An amazing sword]},ench:[{id:16,lvl:5},{id:20,lvl:2}]}
Still think my command was much more 'complicated', but here's to simplicity.
