我有两个题不太明白，也许对于您狠狠简单。所以。谢了。

By focusing on the interesting,_____ the significant,the penny press newspapers of the 1830's helped to change the concept of news.

A which does not necessarily

B not necessarily

C was not necessarily

D nor necessarily being

这个题答案B，我不明白为什么？是插入语？还有第一个逗号前面的是可以删除的介词短语马？

A mobile is a sculpture constructed of parts so delicately connected and balanced ___ the entire suspended structure may be moved by vibration or manual manipulation.

A in order

B making

C with

D that

这个选择D，我想问得是简化后是什么样子。因为看不太懂。空格处到底缺少的是什么成分？

谢谢。
