Answer Choice D?

Hi @JYL,

The first claim mentioned in D is that increases in productivity have virtually stopped. However, the support for the part of the argument in question actually comes in the second half of the second sentence, that farmland is being farmed at peak efficiency. The reason that we predict future rises will not happen is not because production has been flat recently, but because we are already at maximal production with current farmland.
