Planting peach trees on their farm makes more sense for the Johnsons than planting apricot trees. Although fresh, locally grown apricots are very popular in this area, the same is true of peaches. However, individual peach trees cost much less to purchase and plant than do apricot trees, and peach trees also begin bearing fruit at a much younger age.
The statement 'Fresh, locally grown apricots sell at a much higher price than do fresh, locally grown peaches' would most seriously weaken the argument.
