Which of the following most logically completes the
passage?
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____________________.

(A) each of the last two years produced recordbreaking
pecan yields
(B) the quality of this year's pecan crop is no worse
than the quality of the pecan crops of the
previous five years
(0 pecan prices have not been subject to sharp
fluctuations in recent years
(D) for some pecan growers, this year's crop was
no smaller than last year's
(E) the practice of holding back part of oneyear's
crop had not yet become widespread the last
time the pecan crop was as small as it was this
year
