a, n = nil
puts "Please enter 5 words"
until (a = (gets.scan /[\w'-]*/) - [""]).length == 5
  puts "Please type in exactly FIVE words, thanks."
end
puts "You would like to print out which word number? (1-5)"
until (1..5).include? (n = gets.chomp.to_i)
  puts "Please pick a number 1 through 5"
end
puts a[n - 1]
