Argentina and Britain announced an agreement Thursday to restore full diplomatic ties nearly eight years after they fought a 74-day war over the Falkland islands.
Argentina and Britain fought for four weeks over the Falkland islands.
It is definitely incorrect because the timeframe is different as four weeks does not equal 74 days. I think it was difficult for the system to recognize this because I changed the unit of time from days to weeks.
