Pecan growers get a high price for their crop when pecans are comparatively scarce, but the price drops sharply when pecans are abundant. Thus, in high-yield years, growers often hold back part of their crop in refrigerated warehouses for one or two years, hoping for higher prices in the future. This year' s pecan crop was the smallest in five years. It is nonetheless quite possible that a portion of this year' s crop will be held back, since __. Which of the following most logically completes the passage?

C: each of the last two years produced record- breaking pecan yields
D: for some pecan growers, this year's crop was no smaller than last year's
Choose A, B, C or D as your solution.
