So it is a bit confusing when vos Savant fields such queries[query] from the average Joe （whose IQ is 100）as, What’s the difference between love and fondness?Or what is the nature of luck and coincidence?

观察句子要统筹把握，瞻前顾后。

1. field：及物动词。意思是“即时回答”。

2. such queries as：表示列举。as 后面的宾语是两个问句 “What’s the difference between love and fondness?Or what is the nature of luck and coincidence?”  应加引号，跟句子主干予以区别。这里，用 as 列举了 queries 中的两个问题。
