2016 OG verbal分册 SC提问

关于OG2016 verbal分册SC板块有几道题目不太明白，想问问大家：
5.the volumious personal papers of Thomas Alva Edison reveal that his inventions typically did not spring to life in a flash of inspiration but evolved slowly from previous work.
这句正确选C 。我不明白为什么前面有did 后面evolve不是原型而是过去式呢？
8。Standing 12 feet tall,weighing 9000 pounds,and wielding 7-inch claws,Megatherium americanum,a giant ground sloth。。。这个我是完全没有头绪，看解析也没懂。It stood twelve feet tall, weighed nine thousand pounds, and wielded seveninch claws, and Megatherium americanum, a giant ground sloth, may have been the largest hunting mammal ever to walk the Earth.
正确的是Standing twelve feet tall, weighing nine thousand pounds, and wielding seven-inch claws, Megatherium americanum, a giant ground sloth,26Analysts believe that whereas bad decisions by elected leaders can certainly hurt the economy, no administration can really be said to control or manage all of the complex and interrelated forces that determine the nation's economic strength.
答案是no administration can really be said to control
38\Around 1900, fishermen in the Chesapeake Bay area landed more than seventeen million pounds of shad in a single year, but by 1920, overfishing and the proliferation of milldams and culverts that have blocked shad migrations up their spawning streams had reduced landings to less than four million pounds.
答案是that blocked shad from migrating up their spawning streams had reduced landings to less
请大神指点咯

5.did not spring to life in a flash of inspiration but evolved slowly
not but平行...都是過去式

8.所以你的問題在哪個點上?看不懂所以就寫一次我看題的順序
A)It和 Megatherium 中間有and連開變兩個獨立子句了,所以it沒有指代->錯

B)run on兩個動詞沒有and連接

C)The giant ..., it 不是句子,錯

E)Standing twelve feet tall, weighing nine thousand pounds, it wielded seven-inch claws, and the giant ground sloth Megatherium americanum        it多餘,而且這樣變it為standing/weighing的主詞,dangling

38.同學您的問題在哪阿QAQ
寫出疑惑點解釋會比較方便
