Positing an enormous volcanic explosion at the end of the Permian period would explain the presence of a buried crater, account for the presence of the element iridium (originating deep within the earth), and the presence of quartz having been shattered by high-impact shock waves.
account for the presence of the element iridium (originating deep within the earth), and the presence of quartz having been
of the element iridium (originating deep within the earth), and of quartz
the element iridium (originating deep within the earth), and explain the presence of quartz having been
the presence of the element iridium (originating deep within the earth), and explain presence of quartz
explain the element iridium (originating deep within the earth), and the presence of quartz
题目分析：
本题看似难词比较多，但实际上考查了非常简单的平行。本题的大概意思为：定位一个爆炸可以解释一些现象的出现，这些现象包括“埋在地下的陨石坑”，“铱元素（the element iridium）”，和“石英（quartz）”。因此，此三者需要在语法上保持平行。只有选项(B)保证了语法的平行，答案为(B)。
选项分析：
略。
如果去掉B选项两个of, 变成presence of a buried crater, the element iridium (originating deep within the earth), and quartz 是否一样正确？

我觉得可以。最好的最没有歧义的方式应该就是题中的方式。最简洁的方式但是不便于读者阅读的就是你提的方式。还有一个就是explain the precense of ..., the precense of ..., the precense of .... 老师写的那本阅读长难句的书里很多内容很有启发。许多科研文章的句子都是要省略的，但是极简的省也不是好事。。
不可以吧 因为从第二个和第二个平行项来说都加上了presence of...那后面的平行结构也应该如此
