一道SAT语法题 11年5月份真题

A basin,which is where they thought previously
B basin as they had previously thought

\x05The discovery of geysers erupting from the floors of several oceans convinced scientists that hydrothermal vents exist around the world rather than only in the Pacific_________________________.
A basin,which is where they thought previously
B basin as they had previously thought
但不知道A哪里错了
因为科学家们的错误猜测是在过去的过去,所以要用过去完成时态.仅凭这点就可以排除A了.除此之外,A的分句并不完整,副词的位置也不对,其实一定要which is where这种很啰嗦的句式也不是不可以,但语法正确的也应该是这样的 ...rather than only in the Pacific basin,which is where they had previously thought they to be.但这样的话第二个they就又可能产生歧义,为了避免就必须说完整,即 ...which is where they had previously thought the vents to be.如何,是不是更啰嗦了?所以还是别用这个句式的好.
