Warden: The co-operative asks to end the alp's rotation, and the district's ecologists say the rotation is what keeps the meadows rich in flowers. We count flowering stems in the last week of July in each of the alp's six paddocks. The rotation has been kept to exactly, and the count has fallen in every one of the last six years. So the rotation is not what has kept the meadows rich.

Which one of the following, if true, most strengthens the warden's argument?

AOf the six paddocks, the two the rotation leaves ungrazed longest have lost flowering stems faster in each of the last six years than the two it rests for the shortest time.

BThe alp's snow has cleared earlier in each of the last six springs, and the plants come into flower sooner when the snow goes early.

CThe co-operative's herd has been the same size throughout, and it grazes each paddock for the same days, and in the same order, as when the rotation began.

DIn the last week of July the alp's paddocks still carry more flowering stems to the hectare than any other pasture in the district that the warden's people count, whether it is rotated or not.

EThe district's ecologists have never counted the alp's stems themselves, relying on the co-operative's returns.
