If I compose an online trivia quiz for general users, and create questions such as
- Q1) To which Hogwarts House did Harry Potter belong ? (based on a Harry Potter book)
- Q2) Does a honey badger attack a lion ? (based on a specific National Geographic video)
- Q3) Who said this in 2002 "..." ? (based on an article in say, TIME magazine)
Is this a violation of any copyright law ? Am I expected to take explicit permissions etc. ?
