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 Richardson believes that the 【R37】______needs to be withdrawn, as the U.S. provides most of the world’s helium.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] 【R38】

选项

答案 incentives

解析 此处的He指代上文的Richardson,故可定位至E段末句。该句Richardson指出,将氦气的价格升高20—50倍会让人们有动机去循环利用。其中twenty-to fifty-fold increase in prices与题目higher costs相对应,而to recycle与题目use the resource many times over为同义表达,且由题目可知应填入名词,故答案为不定式to recycle修饰的incentives。
