基本上finite clause是单独拿出来可以独立成句的从句，所以although + ving/ ved/adjective是不行的

不太同意
我还是觉得OG对于although+ving这种形式的搭配直接一棍子打死，但是although+ving的确出现在OG的官方正确答案中

所以although+ving这个点我觉得不能是死记硬背来排除的
although+ving这个形式是没有错的

但是看到省略的形式一定要马上去考虑逻辑主语

E选项逻辑主语是Earth，Earth不能去cover整个行星，只有尘埃才可以，这里是句意的分歧点（所以E就被排除了）
在这类although+ving所谓的状语从句省略上，我个人觉得OG的解释过于敷衍，与我们学习的语法知识有所出入吧，或者说排除得过于简单（仅仅因为idiom或相近的缘故）
考虑逻辑主语似乎是一种更有自信的做题方法

PS：个人看法

OG12例子：

35： Along with the drop in producerprices announced yesterday,the strong retail sales figures released today seem toindicate that the economy, although growing slowly,is not nearing arecession.

prep07：
17：Although unhappy with the high rent hercompany was paying for its suburban office building,
the chief executive recognized that rental rates for buildings in the suburbswere far lower than those typically charged for property located within the citylimits  


28：Although eradicated in the United States,polio continues elsewhere and could be  
brought into the country by visitors.



我记得有一题是although+ving作为正确选项的，一时半会想不起来了


prep07 28题就把although +VED作为了正确选项，是考察的划线部分！


其他两个例子都是未划线部分


GMAT SC没必要搬石头砸自己脚


所以还是觉得OG的解释有点欠妥当
