A characteristic of farmland strongly distinguishing it from timberland is its:
选项:
A.commodity price-driven returns.
B.inherent rigidity of production for output.
C.value as an offset to other human activities.
解释:
B is correct. Unlike timberland products, farm products must be harvested when ripe, so there is little flexibility in the production process. In contrast, timber (trees) can be grown and easily “stored” by simply not harvesting. This feature offers the flexibility of harvesting more trees when timber prices are up and delaying harvests when prices are down.
