问题 Many experts who favor genetically modified foods believe that genetic engineering can help to meet the demands of the world’s increasing population. [br] The two factors contributing to the appealing of GM crops to farmers are and ______.

选项

答案 operation simplification, yields increase

解析在文章“Fewer Poisons in the Soil"部分中，谈到基因改造作物时，作者说"The herbicide tolerant types survive when exposed to broad-spectrum weed killers，potentially allowing farmers to forgo more poisonous chemicals that target specific weed species. Farmers like to limit the use of more hazardous pesticides when they can, but GM crops also hold appeal because they simplify applications(reducing the frequency and complexity of pesticide applications) and, in some cases , increase yields".
