premise: Figures released today show that the number of organs donated by New Zealanders in 2006 has decreased by four to a new record low of 25. In 2005 the number of organs donated equalled 29, a previous record low in New Zealand. Before 2005 the number of organ donations averaged 40, an already low number by international standards.
hypothesis: If the trend continues, New Zealanders will donate fewer organs in 2007 than in 2006. 
reason: The trend is that there are fewer organs every year. If this continues there will be fewer organs donated in 2007. My statement is correct.
