答案

What主语,can be done 在一起做复合谓语,to harness做宾语
and并列连词,give做并列句的谓语,the public 做并列句的宾语,the scientific background做并列句的间接宾语
It做形式主语,need做谓语,to make informed decisions做宾语,on subjects like acid rain做状语,其中的like acid rain做介词状语中subjects的定语,the greenhouse effect,nuclear weapons,and genetic engineering,做like（这里是介词）的并列宾语
