I think these were good practice for quidditch. I'm proud to say I was able to find all the answers in the book.
1- Who wrote the obituary of Dumbledore in The Daily Prophet? Elphias Doge
2- What is a Squib? A non-wizard born of wizard parents
3- Who stole the locket Horcrux from the Black House? Mundungus Fletcher
4- What are the Albus Dumbledores' siblings names? Aberforth and Ariana
5- Where did Hermione leave the money for the eggs and bread that they
stole from the lonely farm? Under the chicken coop.
6- What is the quote Lily and James Potter have on their tombstone? The last enemy that shall be destroyed is death.
7- Why did Gilbert Grindewald leave wizarding school? He was expelled from Durmstrag for performing “twisted experiments.”
8- Where does Xeno Lovegood first say that Luna is when Ron, Hermione and
Harry visit? Down at the stream, fishing for fresh water plimpies.
9- What wood is the wand from The Deathly Hallows supposed to be made out of? Elder
10- How did Harry, Hermione and Ron escape the vaults of Gringotts? On the back of a dragon
11- What is the name of the all-female Quidditch team that Ginny has a poster of in her room? Holyhead Harpies
12- Describe what the Undetectable Extension Charm is. A spell placed on an object that makes the inside bigger than the outside, like Hermione’s bag. I also believe one was cast on my Ford Focus, because I can pack more stuff in there than you’d ever believe. My car’s name is Hocus Focus because of this.
