拙见
第一题，In no other historical sighting放句首，凸显本题比较的重点 就是时间（og官方解释中提过把xx放句首有凸显xx的作用）、
第二题，除了BC 其他选项都是双主语，但是B中 being ··as compared  wordy 关于being的wordy可以看prep08笔记 很详细的讲解过，  
所以在我看来第二题根本不是分不清比较什么的问题，是基本的语法问题
所以建议不要纠结自己看不出来比较什么，
掌握语法知识点，
见招拆招，兵来将挡

当然，很多语法错误足以排除掉错误选项，选出正确的，但是现在sc重点考语义了，所以我比较想刨刨根儿，哈哈！！
还有，不太懂你说的双主语是什么，这也算是错误吗，顶多算是冗余吧？？

双主语的意思就是两个independent clause仅仅通过一个逗号链接，而缺少conjunctions，这是一类经典的GMAT错误类型。

第二题中A,B,D个人认为更主要的错误是logical predication 错误，因为这些答案都对比的是人v.s地方。 E是double subject 错误。
