GWD2 Q34
?NASA’s methodical approach to the exploration of Mars has not yet answered the questions of whether biological life forms ever emerged on Mars and whether, presuming such life forms having left fossil traces to begin with, those traces can still exist in some moist recesses of the cold and arid planet.
A.and whether, presuming such life forms having left fossil traces to begin with, those traces can
B.B.and whether, if it is presumed that such life forms left some fossil traces to begin with, can those traces
C.C.and whether, presuming such life forms left fossil traces to begin with, those traces
D.D.and, presuming such life forms did leave some fossil traces to begin with, if they can
E.E.and, presuming such life forms to have left fossil traces to begin with, if theyE.and, presuming such life forms to have left fossil traces to begin with, if they
答案是C，我排除后也选C，但是想问下，C中那个 presuming such life forms left fossil traces to begin with会不会放的位子不好，会被认为是其逻辑主语的those traces？

来说说吧

我觉得不会，因为句子前面有主语了，然后在出现presuming，那他的逻辑主语很定是前面的。如果句子是presuming引导的话，那么他的主语才在后面

这里的 presuming 引导的是一个插入语，不是一个状语成分，因此不会产生“夹心饼干”的问题。
再说，如果 those traces 是 presuming 的逻辑主语，即要求 those traces 是 presuming 的动作发出者，这样说不同，presume 的是人，而不应该是 traces

请问如何看出presuming是插入语，而不是状语成分？貌似即便是状语成分，也是and whether, 状语成分, SVO 吧？
presuming放在这里，会不会让人找它的逻辑主语呢？一找发现全局没有一个名词可以充当它的逻辑主语

1. Critical-thinking instruction is predicted on two assumptions: that there are clearly identifiable thinking skills that students can be taught to recognize and apply appropriately, and that if students recognize and apply these skills, they will become more effective thinkers.
( and that if students recognize and apply these skills, ....) => This structure bears no coma between "that" and "if", so it’s 状语成分)

2. Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide and that, if it were to strike Earth, could do tremendous damage to part of the planet but would probably not cause planetwide destruction.
(and that, if it were to strike Earth, ... .) =>This structure bears a coma between "that" and "if", so it’s 插入语)
