Paragraph 4    These ideasremain controversial. Proponents point to features such as the terraced“beaches” shown in one image, which could conceivably have been left behind asa lake or ocean evaporated and the shoreline receded.Butdetractors maintain that the terraces could also have been created bygeological activity, perhaps related to the geologic forces that depressed theNorthern Hemisphere far below the level of the south, in which case they havenothing whatever to do with Martian water. Furthermore, MarsGlobal Surveyor data released in 2003 seem to indicate that the Martian surfacecontains too few carbonate rock layers―layers containing compounds of carbonand oxygen―that should have been formed in abundance in an ancient ocean. Theirabsence supports the picture of a cold, dry Mars that never experienced theextended mild period required to form lakes and oceans. However, more recentdata imply that at least some parts of the planet did in fact experience longperiods in the past during which liquid water existed on the surface.

当时就在BD项里纠结，后来感觉D更详细就还是选了D，但是错了。看答案的时候又看了一遍，还是不知道D错在哪里？是因为so... that的句式导致的逻辑关系错误了么？谢谢大家~~~

原句是could also have been提出的是另一种可能性，但是d选项却极端的说不可能是因为水形成的，所以错误
