关键字：by引导方式方法状语表示同义关系后面的一系列是否通过政府审核什么的内容与解题无关，因而在做题时直接简化句子为：The plan would save the aquifer by reducing pumping to ______ levels.空格中应该填入一个形容词，表示所达到一种能够挽救aquifer的水平的程度。由于by引导的是方式方法状语，前后两个半句是同义关系，又没有否定词存在，因而对应词语之间是同义关系，也就是应该填入“拯救”的作用的同义词。词语解释：
[1].(A) innocuous：(无害的)producing no injury : HARMLESS
[2]. (B) feasible：(可行的)capable of being done or carried out
[3]. (C) practicable：(可行的)capable of being put into practice or of being done or accomplished : FEASIBLE
[4]. (D) minimal：(最小的)very small or slight
[5]. (E) remedial：(补救的)intended as a remedy
[6].(F) benign：(良性的)of a mild type or character that does not threaten health or life
