Question ID:PT72 S2 Q9 Passage:There are many agricultural regions in North America where the growing season is long enough to allow pumpkin production well into autumn with no risk of frost. Nonetheless, pumpkin production in North America is concentrated in regions with long, cold winters, where the growing season is delayed and pumpkin crops are exposed to risk of damage or destruction by early autumn frosts. Stem:Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above? Correct Answer Choice:DChoice A:Pumpkins are usually grown to reach maturity in autumn. Choice B:Pumpkins depend on bees for pollination, and bees are active only in warm weather. Choice C:More pumpkins are sold to consumers in regions of North America with long growing seasons than to those in regions with short growing seasons. Choice D:Prolonged cold temperatures kill soil-borne fungus and other sources of disease that would kill or seriously damage pumpkins. Choice E:Most of the pumpkin seed used by growers in North America is produced in areas where the growing season is long, and plants used for seed production are protected in greenhouses.
