求讨论2道题，来自prep08语法笔记252&258题，关于that省略以及句子完整性的问题。

正在学习prep08语法笔记，下列两题有疑问，虚心求教。谢谢！

第252题：Although producer prices rose at an unexpectedlysteep rate in September, analysts said that the increase resulted mostly fromtemporary factors and not necessarily foreshadowing that there would bea resurgence of inflation.

A.    factorsand not necessarily foreshadowing that there would be

B.     factorsand not necessarily that it foreshadowed

C.    factors and did not necessarily foreshadow

D.     factors, while not necessarily a foreshadowingof      (C)

E.     factors,while it did not necessarily foreshadow that there would be

上题正确答案C，但怎么看都觉得and后面的句子不完整，我的理解是，and后面的部分也是said that的宾语从句部分，那么是否应该加个it更合适？还是我对句子的解构有错误？

第258题： In an attempt to produce premium oysters, a firm in Scotland has developed a prototype of a submersible oyster farm, sitting below the surface of the ocean, and it provides ideal conditions for the mollusks' growth.

A.     farm, sitting below the surface of the ocean, and it provides

B.      farm, sitting below the surface of the ocean for providing

C.     farm that sits below the surface of the ocean and providing

D.     farm that sits below the surface of the ocean and provides      

E.      farm that is sitting below the surface of the ocean and it provides

上题正确答案为D，也就是说provides跟sits平行，共同修饰farm，但是印象中，两个从句并排，第二个也是要加that开头的。不知我的理解是否正确？还是此选项有什么其他理解玄机？

baby姐的帖子里说过，平行就是比选美，找个最美的就行了，第二题你说加that没问题，可是不加也没啥影响，况且没有比答案更美的了。
第一题我觉得是result from 和foreshadow之间的平行，

Although producer prices rose at an unexpectedlysteep rate in September, analysts said that the increase resulted mostly fromtemporary factors and not necessarily foreshadowing that there would bea resurgence of inflation.                                              我想问一下said that后面不应该是一个完整的句子么？为什么不是the increase was resulted from，而是直接increase resulted from
