Answer:
each of the last two years produced record breaking pecan yields.
Explanation:
Pecan growers tend to store Pecan when the crop yields a high yield, so in times of scarcity these growers can use the stored Pecan nuts to continue generating income for their production. From this we can conclude that if this year's nut crop was the smallest in five years, it is possible that part of this year's crop will be held back, since each of the last two years has produced a record nut yield.
