3. The Switch: You turn 2 switches "on" and leave 1 swtch "off" and wait about a minute. Then enter the room, but just before you enter, turn one switch from "on" to "off". Once in the room, feel the light bulb - if it is warm, but off, it has to be the last switch you turned off. If it is on, it has to be the switch left on. If it is cold and is off, it has to be the switch you left in the off position.

2. The Cake: The cake is not in the CAKE box, and it cant be in the COOKIE box, because that's the only place for the fruit. So it must be in the box labelled FRUIT.

1. Man with a fox: Take the goose over first and come back. Then take fox over and bring the goose back. Now take the corn over and come back alone to get the goose. Take the goose over and the job is done!
