Seed bank curator: We hold two thousand barley varieties, and each is grown out in a trial plot every tenth year so that fresh seed can be collected before viability falls. Last year's grow-outs yielded far fewer seeds per plant than the same varieties yielded when they were last grown out. Something in the collection is deteriorating, and the ten-year interval must be shortened.

Which one of the following, if true, most weakens the curator's argument?

ANothing distinguished last year's grow-outs from the earlier ones except the ground: the trials had moved to a field whose growing season is a fortnight shorter.

BShortening the interval would mean growing out more varieties in a single season than the bank's ground and field staff have ever carried, and no further land has been offered to the bank.

CGermination tests on the stored samples of these varieties show that not one has held the germination rate it had at the previous grow-outs.

DThe share of the collection grown out each year has fallen, though the number of varieties grown out has risen.

EThe bank's field staff are fewer than at the previous round of grow-outs, and fewer trial plots can be sown and tended in a season.
