Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on
the surface of the Sun but have never been sighted on the Sun’s poles or equator.

(A) are visible as dark spots on the surface of the Sun but have never been sighted on
(B) are visible as dark spots that never have been sighted on the surface of the Sun
(C) appear on the surface of the Sun as dark spots although never sighted at
(D) appear as dark spots on the surface of the Sun, although never having been sighted at
(E) appear as dark spots on the Sun’s surface, which have never been sighted on
这题选A，OG上面关于选项的解释都知道。
我的问题是，这个but引导的句子如果把but换成although，且不谈but和although意思上的区别，会不会改变句子的重心？
也就是but引导的句子是句子重心，而although从句前面的句子才是重心。我这些理解对吗？
还有gmat题目里面会考虑句子重心的转移吗？

谢谢各位大大！

1，会，改成although以后句子中心集中在前面。
2，BUT常常引导的是中心......但是个人感觉平衡一些，不知道是不是我的错觉
3，有的题会考虑，参考“某人给某人写信”那道题，考虑了句子中心是通信起止时间还是通信内容。

谢谢ben，前面的都理解。
关于3中提到那个通信的题目我想问，真正句意想表达的是不是根据A选项翻译来确定啊？
也就是如果后面的选项把A选项的句意重心改变了，是不是就一定是错呢？
29 .Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and Ending shortly before Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.
(A)    Dickinson were written over a period beginning a few years before Susan’s marriage to Emilys brother and ending shortly before Emily’s death in 1886, outnumbering
(E)  Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumber
如果是不考虑A的comma+分词结构使用错误，是不是就选A了呢？

嗯，原题A这样有这个硬伤
如果把doing短语放在句首变成主语补语的话，我觉得就没什么问题了......
所以其实需要用语义中心的时候一般都很明显。
