OG12语法第一题中的解释说道将“because”改成了"since"改变了原来的逻辑关系，since不能表示因果关系吗？

1.    The Glass House Mountains in Queensland, Australia,
were sighted in 1770 by the English navigator Captain
James Cook, bv whom thev were named supposedly
because its sheer wet rocks glistened like glass.

(A)    by whom they were named supposedly
because its
(B)    by whom they were named supposedly and their
(C)    naming them supposedly since their
(D)    who so named them supposedly because their
(E)    who so named it since supposedly their
答案为D
参考答案中C的解释写到the preposition since loses the important causal logic of the sentence.

since一般翻译为既然，就是显而易见的事。这里OG答案强调的是because的解释作用，用since不太恰当吧

再请教
og 解释是【the preposition since....】 那since在gmat里面只能是介词么……？

同问！！！！since怎么看出来这里是介词？？？

可能since在GMAT里只能作介词吧,比如 since 1990, since last month
同意4楼, since 用于解释因果的话语气较because弱.

参考答案中C的解释写到the preposition since loses the important causal logic of the sentence.

OG 说，since 是preposition，是个前置词。。只有在since位于句首的时候才表因果关系

since当介词讲的时候表自。。。以来，自。。。以后
