Ling avoids your gaze as she speaks. "Have you
ever seen a teakettle without an escape valve? The
steam builds up until the kettle explodes. That,"
she says ominously, "could happen to this island if
water continues to flow down into the volcano
afer we blow up the steam pipes. The whole place
could go up like Mount Saint Helens."
  "Then we should blow up the water pipes in-
stead," you say reasonably.
  "You're right, but that's not possible. The water
pipes go directly from the lake down to the core.
Our only chance to stop the plant is to blow up the
steam pipes. I'm hoping that the Omicron Masters
have installed escape valves."
  "You're hoping?" you say.  Ling's plan is sound-
ing less and less certain, and you're worried about
Bill. "What you're telling me is that if our plan goes
wrong, we can still get away in the hang glider."
  "Yes," Ling says, with an uncomfortable smile.
  "But what about Bill? you ask.  "Will that thing
hold all of us?"
  "It wont hold three, I"m afraid," she replies.
"But if you're concerned about your friend, I have
a small inflatable boat.  If you'd like, you can use it
to escape with Bill while I sabotage the power
plant. But chances of something going wrong
seem remote."
  "Yeah," you say doubtfully.

If you decide to take the boat and rescue Bill
If you'd rather go with Ling to the power plant
