D选项里though 和but同时使用有问题，而且though后面跟的是省略句，而but后又接了完整句，不对称。这样改或许会好些：Called a sea but actually the largest lake on Earth,the landlocked Caspian covers
E选项的逻辑意思有问题，也就是OG的解释Despite being called a sea indicates , somewhat illogically, that the largest lake being called a sea would lead one to expect it not to be the Caspian" despite 表示句意为转折，前面是called a sea 所以主句就应该是sea的反义词lake对应，而E中把这种逻辑对应关系弄反了。简化后句型应该为：Despite being a sea, it's actually a lake.
