Continuity mistake: Harry buys the book "One Thousand Magical Herbs and Fungi", but later, the title changes to "One Hundred Magical Herbs and Fungi".

Continuity mistake: While being sorted into houses, Harry looks up at the Sorting Stool, and there are only three people left to be sorted. Professor McGonagall then calls out the names of four more kids.

Factual error: On page 25, it mentions that the boa constrictor at the zoo winked at Harry. Snakes don't have eyelids at all, so it's impossible for them to wink.

Answer: Yes. J.K. Rowling was going to give Hermione a younger sister who was a muggle. However, by the time "Harry Potter and the Order of the Phoenix" came out, she felt that it was too late.

Question: Has it ever been explained what happens to a wizard/witch if they don't repay a life debt? Harry should owe one to Snape after Snape rescues him from Quirrell's curse during the Quidditch game, but he never does throughout the series.

Answer: It does not appear that life debts automatically form whenever somebody saves somebody else - J K Rowling has, for example, stated that Ginny did not incur a life debt to Harry when he saved her in the Chamber of Secrets, although she said nothing about what circumstances need to occur for a debt to exist. In Snape's case, there would seem to be several possibilities. 1) A life debt simply didn't form. 2) Snape is protecting Harry because of his love for Lily and his failure to save her, so he may actually be paying off a debt of sorts himself by doing so. 3) Harry's father James saved Snape from almost certain death when Sirius tried to trick him into going into the Shrieking Shack when Remus Lupin was in his wolf form. As such, Sirius may have owed James a debt, which he paid off by saving Harry. 4) A life debt did form but, as Snape died before Harry could pay it off and, insofar as we know, had no relatives that the debt could pass to, Harry was let off the hook.

Question: This question is for all the novels. How are all the schools in the wizarding world kept hidden from the muggle world? Surely if a plane were to fly over Hogwarts, people would be shocked at seeing people flying around on broomsticks and using magic.

Answer: The International Statute of Wizarding Secrecy is in charge of hiding the general wizarding community from the Muggle world. As for many of the wizarding schools such as Hogwarts, their use of multiple Concealment Charms provide the necessary protection to creatively conceal them from Muggle view.

Also, Muggles usually don't "want" to see magic. Most of them are too convinced that magic is not real. A Muggle might see the occasional wizard/witch fly high above them on a broom, and assume they imagined it.

Answer: There are special spells at work to hide the schools and other places from muggles. In Deathly Hallows for example you can see Hermione cast a few when they are in the woods. An example is "Repello Muggletum", which is a barrier that causes Muggles who hit it to forget they were there and turn around.
