  One of the primary shortcomings of the HomesteadAct of 1862, a program through which the federalgovernment offered free plots of land to US citizenswilling to establish farms in the American West, wasthat the plots were too small to sustain a farm.Plots in the Great Plains were best left halfunplanted each growing season to conserve water. The Great Plains region receivedtwenty or fewer inches of rain per year and was considered semiarid. With farmsconsisting of a mere 160 acres, however, this practice would not have produced sufficientharvests. Moreover, raising cattle was impossible because the tiny homesteads would quicklybecome overgrazed. According to geologist and explorer John Wesley Powell, sustainablehomesteads on the Great Plains actually needed to be a staggering 2,560 acres.

  Which choice most effectively combines the underlined sentences?

  A.Receiving twenty or fewer inches of rain per year, land in the Great Plains was best left halfunplanted each growing season; the reason for this was to conserve water in this semiaridregion.

  C.Land in the Great Plains region, being semiarid, was best left half unplanted each growingseason to conserve water, and it received twenty or fewer inches of rain per year.

  D.Land in the semiarid Great Plains region received twenty or fewer inches of rain per year, soplots there were best left half unplanted each growing season to conserve water.
