6. • You are driving along in your new two-
seater Porsche on a bitterly cold, snowy,
stormy night. You pass by a bus stop, and
you see three people waiting for the bus:
– An old lady who looks as if she is about
to die.
– An old friend who once saved your life.
– The man/woman of your dreams.
Which one would you choose to offer a ride
to, knowing that there could only be one
passenger in your car?
7. One solution:
"I would give the car keys to my old friend, and
let him take the lady to the hospital. I would
stay behind and wait for the bus with the
woman of my dreams."

10. You’re in your new home and have a
little problem. On the top floor are
three incandescent lights. On the
ground floor are three switches which
control the lights, presently all in the
"Off" position. You don't know which
switch controls which light, except that
there is a one-to-one correspondence.
You're alone on the ground floor and
want to label the switches but you
want to do it in as few trips upstairs as
possible.
What is the minimum
number of trips this takes?
11. Here’s a way to accomplish this in one trip.
• Turn two switches to the "ON" position.
• Wait a few minutes.
• Turn off one of the two switches.
• When you reach the three lamps on the top
floor, one light will be on (the switch that is
still on),
• one light will be off and cool (the untouched
switch),
• one light will be off, but still warm (it was on
but then switched off)
