GWD4-30

Q30:

Under high pressure and intense heat, graphite, the most
stable form of pure carbon, changes into the substance commonly referred to as
diamond and remaining this way whether or not the heat and pressure are
removed.

1. remaining
        this way whether or not
2. remaining
        like that even as
3. remaining
        as such whether or not
4. remains
        in this way although
5. remains
        thus even when

first,E's meaning is wrong

second,“remain” is a vi.

third,if using "thus even when",it should be followed another sentence,otherwise the whole sentence is illogical

D 很对啊。 D和E项的主要区别我觉得在于意思上有差异，E里 even when 有表示假设的意思，而D的although。。。表示after 石墨转变为钻石，heat and pressure is removed 这个事实 。

E的thus 和 even when 不能连用．用一个就好了．语义重复了. 都表示即使如此．　

skyyuki11的解释是错的．其实原句本来的意思就是包含了现实和假设两种情况的．但D选项没有语法错误．尽管逻辑不对的．

应该是e，even when：即使当。。。

thus确实有表示in this manner的意思，逻辑意思来讲并不重复

我开始也选的d，语法没错，但是though用的感觉比较突兀
