But extra wax can harden and form a【S7】______that interferes with sound waves and reduces【S8】______. People can also cause a blockage when they try to【S9】______out their ears, but only push the wax deeper inside.

选项
答案
K
解析
此处空格为动宾结构,应填名词。前文的意思是耳垢具有保护作用,下文用also可知是承接上文的意思。名词中blockage是“堵塞”,根据常识可知耳垢不具有防止堵塞的功能。infection是“感染”之意,自然当选。
