the reason your answer may be marked incorrect is you didn't use all lower case. example: Hufflepuff (will be incorrect) hufflepuff (will be correct) note: names will need first and sir names! note: for dumbledore, only what you think his FIRST name! if you add "dumledore" at the end, it will say incorrect! example: hermione (will be incorrect) hermione granger (will be correct)
