Once there was a girl named Yuri. She lived in Kakegawa, Japan. Yuri loved to watch tv programs about other countries. She dreamed of visiting many places and making friends all over the world.
One night, Yuri was lying in bed, listening to the rain, when she heard a "bang, bang, bang" coming from her wardrobe door.

Should Yuri...


a) open her wardrobe

b) stay in bed where it is safe.
