Which of the following quotations most clearly illustrates the original purpose of the fire?
"He cleared his throat and went on.
'Will you light the fire?'
Now the absurd situation was open, Jack blushed too. He began to mutter vaguely.
'You rub two sticks. You rub-'

"The boys were dancing. The pile was so rotten, and now so tinder-dry, that whole limbs yielded passionately to the yellow flames that poured upwards and shook a great beard of flame twenty feet in the air. For yards round the fire the heat was like a blow, and the breeze was a river of sparks. Trunks crumbled to white dust."
"There's another thing. We can help them to find us. If a ship comes near the island they may not notice us. So we must make smoke on top of the mountain. We must make a fire."
"'We haven't made a fire,' he said, 'what's any use. We couldn't keep a fire like that going, not if we tried.'

'He helped that way.'"
"'We've got to have special people for looking after the fire. Any day there may be a ship out there' - he waved his arm at the taut wire of the horizon - 'and if we have a signal going they'll come and take us off. And another thing. We ought to have more rules. Where the conch is, that's a meeting. The same up here as down there.'"
