Every nutrient tank at the Wenlow glasshouse is dosed to a fixed conductivity, and conductivity rises with any salt in the water, whether the plants can take it up or not. The bore that feeds the glasshouse has carried a rising load of sodium since the spring. The dosing controller has called for less feed each week since then, and the controller has not been altered.

Which one of the following is most strongly supported by the statements above?

AThe plants at Wenlow are underfed to some degree, the controller having called for less feed each week since the spring while nothing has reduced what the crop needs.

BAt least part of the rise in the bore's sodium is owing to the controller's calling for less feed, a tank at fixed conductivity drawing more from the water.

CEvery glasshouse on that bore has been underfeeding its crop since the spring, as such a controller must.

DThe crop at Wenlow has less to draw on that it can actually use than it had before the spring, sodium being a salt no plant can make anything of, though by how much is not settled.

EThat the controller now calls for less feed than it did is not evidence that the crop needs less, since part of what it reads may be salt the plants cannot use.
