On the shelf stand volumes 1, 2, and 3 of the first edition of Soseki's I Am a Cat. The books have been lying there for a long time, and moths have dug a tunnel from page one of volume 1 to the last page of volume 3. The paper in each volume is 3 centimeters thick and its cover is 1 centimeter (front and back covers are 5 millimeters each). Can you tell how long the tunnel is?

Several children were playing in my backyard. Sud denly I heard the noise of a window breaking. I dashed out and saw four children looking at pieces of broken glass in my garage. Surely one of the children must have broken the garage window.
"John broke the window," said Ann.
"No, Gail did it," said John, grinning.
Gail's sister Sally declared, "It wasn't me!"
Gail said, "Me? John is a liar to say I did it."
Of the four children only one spoke the truth.
Who is the culprit?
