A decade ago, (3)_____ the infrared scanning technology developed for military purpose and other satellites, physicist Stephen Paley (4)_____ a quick way to take the temperature of crops to determine (5)_____ ones are under stress. The goal was to let farmer (6)_____ target pesticide spraying (7)_____ rain poison on a whole field, which (8)_____ include plants that don’t have the pest problem.

"This technique can be used (17)_____ 75 percent of agricultural land in the United States", says George Oerther of Texas A＆M. Ray Jackson, who recently retired from the Department of Agriculture, thinks (18)_____ infrared crop scanning could be adopted by the end of the decade. But (19)_____ Paley finds the financial backing (20)_____ he failed to obtain 10 years ago.

选项 A、to find out
B、to be found
C、to find
D、to be found on
答案C
解析 此题属于语意搭配题。在"名词+be+adj.+to do"结构中，不定式用主动表被动。原句意为：很难找到长期的支持者，故选项to find正确。选项to find out表示"找到(抽象的结果)"，选项to be found是不定式的被动形式，选项to be found on无此搭配。全句可译为：农民们抗拒这种新技术，长期的支持者很难找到。
