  You should say something about what you have tried.  For instance, do you
  know of a function that maps over the cars of a list?  Do you know of a
  function that find the first non-cons car of a cons?

  The United Nations before and after the leadership of Kofi Annan are two
  very different organizations.  The "before" United Nations did not deserve
  much credit and certainly not a Nobel peace prize.  The "after" United
  Nations equally certainly does.  I applaud the Nobel committee's choice.
