premise: Saudi Arabian Oil Minister Ali al-Nuaimi said Wednesday that OPEC had "a little more work to make the market even more stable", a hint the oil exporters' group needed to reduce its output further.
  His comments could mean a further cut in OPEC production target, currently at 26.3 million barrels per day, or greater compliance from OPEC members, some of whom are suspected of producing more than their allocated amount.
  "The fundamentals of the market are much better than they were in October and I think the market is moving towards better stability.
  "We probably have a little more work to make the market even more stable," he said as he arrived here.
  The Organisation of Petroleum Exporting Countries, whose members regulate their oil exports to control the price of oil, took a decision in Qatar in October to cut their output by 1.2 million barrels per day.
   How do OPEC members control the price of oil?
hypothesis: reduce its output further
