Sobotka argues that big business and users of helium need to help look after helium stocks because 【R36】______ will not be encouraged through buying and selling alone. Richardson believes that the 【R37】______needs to be withdrawn, as the U.S. provides most of the world’s helium. He argues that higher costs would mean people have 【R38】______ to use the resource many times over.
People should need a 【R39】______ to access helium that we still have. Furthermore, a 【R40】______. should ensure that helium is used carefully. [br] 【R40】

选项

答案 regulatory agency

解析 根据题目可知,空格处为ensure的主语,故应填入名词或名词短语,由ensure that helium is used carefully可定位至F段倒数第三句,该处指出,监管机构应该把氦气资源保护作为一项强制义务。题目ensure that helium is used carefully是该句受动者conservation具体化的表述,故答案为该句施动者regulatory agency。
