The answers to each question were:

2) What are the spells that Mr. Ollivander performs with Fleur and Krum's wands?
Fleur: Orchideus- a bunch of flowers comes out of her wand
Krum: Avis- a bunch of birds fly out of his wand
3) Who was the caretaker in Mrs. Weasley's day?

Slytherin got all answers correct, so score the full 8 points.
Hufflepuff also had all 4 correct, and also score 8 points.
Gryffindor correctly answered question 1 and 4, but unfortunately only gave the names of the spells (and not the resulting outcomes)
for question 2 and an incorrect answer for question 3, therefore scoring 4 points for the correct answers but giving 4 points to Ravenclaw for the incorrect answers.
Therefore the overall running total house points currently stand at:
Slytherin: 59
Hufflepuff: 40
Gryffindor: 39
Ravenclaw: 10
Which means there has been a reversal in second place (Hufflepuff having overtaken Gryffindor) but slytherin are still out there in the lead.
