You are missing two end before the last one. By the way, if you want to have
several "branches" in your if statement, you can use the elsif keyword instead
of nested else/if. This would make your code shorter and much easier to read
and debug. Here's how it would look:

puts 'You see a lamp on the floor of a dusty room. Do you pick it up and rub it?'
lamp=gets.chomp

if lamp=='No'
  puts 'You turn around, and walk out of the room, always to wonder whether or not you should have rubbed it...'
elsif lamp=='Yes'
  puts 'You walk up to the lamp and stroke it. Suddenly a genie bursts out and says "You have released me from my eternal prison. I shall now grant you one wish! State it in "I wish for (blank)" format 
please. State it, and it shall be done."'
  wish=gets.chomp
  if (wish== 'I wish for world peace' or wish== 'I wish for the end of world hunger')
    puts 'That\'s very thoughtful of you. It shall be done!'
  elsif (wish== 'I wish for the winning lottery ticket' or wish== 'I wish for $1,000,000')
    puts 'That is very selfish of you, but I must hold a promise. Your wish shall be granted.'
  else
    puts 'Your wish is my command.'
  end
end
puts 'You walk out of the dusty room, into the sunshine, awaiting a changed life as a result of your recently granted wish.'

I hope this helps
