Ministry of Education Quiz (Part 6)

• Question: Hook is playing a game called “Guess the Flower Color” with her friends. She invited Julian, Luka, and Big Sister who always plays with them – and stuck a flower in each one’s hair. There are four flowers – two white, two purple – and nobody including Hook looked at their own flower nor anybody else’s flower. Next, she asked everyone to step forward and form a line. Hook, Julian, Luka, and then Big Sister stood in order. Only looking at the person straight ahead is allowed, and nobody may turn around or peek at anyone else’s flower. To keep things fair, Hook blindfolded Big Sister – because she’s so tall! However, while they can’t see their own flowers, we can as we walk by: Hook and Luka have white flowers, while Julian and Big Sister have purple ones. Despite Hook’s best and fairest intentions, only one person in this game will be able to guess what color the flower they have on their head is. Who is that person?
• Answer: Julian (Option 2)

Ministry of Education Quiz (Part 7)

• Question: I heard that there’s ancient treasure buried in an inconspicuous corner of the snow plains. Sampo the explorer – Tall, Blue, and Handsome – found the treasure after quite an adventure, and before them, they found two talking gates: One gold, one silver. One of these two doors only tells the truth, while the other only tells lies. Behind one of these doors lies treasure, behind the other lies an ancient monster. A note on the treasure map advises: The two doors will only answer one question. The quick-witted Sampo – Tall, Blue, and Handsome – gives it some thought before asking the silver door, “What would the gold door say about the thing that lies behind you?” The silver door answers, “It would say, there is treasure behind me.” Which door should Sampo – Tall, Blue, and Handsome – open?
• Answer: Open the gold door. (Option one)
