The availability of carbon dioxide is an essential(i)______for plant life, while oxygen is equally(ii)______for animal life.
选项
答案
C,F
解析
The best answer is C and F. If something is "essential," it is unlikely to be either a choice or a luxury. Therefore, "condition" is the best answer for Blank(i). Blank(ii)must echo this idea, because of the adverb "equally." Consequently, "necessary" is the best choice for Blank(ii).
