bollworms and some other pests.bt is short for bacillus thuringiensis(苏云金杆菌)it was discovered in the early 20th century.farmers began using bt as a natural pesticide(杀虫剂)then，in the 1990s，researchers found a way to grow cotton plants that contain a bt gene.the genetically modified cotton plant produces toxins(毒素) that kill bollworms.farmers around the world are now growing about fourteen million hectares of bt cotton.cotton bollworms also attack other crops.but scientists in china recently reported that bt cotton may help control bollworms in other crops growing nearby.the study involved crops grown in six provinces of northern china between 1992 and 2007.the study area contained three million hectares of cotton and twentytwo million hectares of corn，peanuts，soybeans and vegetables.the researchers say the study suggested that bt cotton not only controls bollworm on the transgenic cotton，but also may reduce its presence on other crops.and that reduction，they say，may decrease the need for pesticide using in general.but the researchers also pointed out concerns.they say bollworms could develop resistance to the cotton plants designed to resist them.and they noted that insects called mirids have become “key pests” of cotton in china.they said this is because of a decrease in pesticideuse made possible by bt cotton.the researchers say they do not believe that bt cotton alone can solve all insect problems.instead，they say farmers in china should consider it just one part of pest management systems.kongming wu of the chinese academy of agricultural sciences in beijing led the study.the findings appeared in science magazine.1the underlined word “ones” in paragraph 1 refers to _.abacillus thuringiensisbbollwormsccotton cropsdpesticides2which of the following
