257. The direction in which the Earth and the other solid planets --Mercury, Venus, and Mars -- spins were determined from collisions with giant celestial bodies in the early history of the Solar System.

(A)  spins were determined from

(B)  spins were determined because of

(C)  spins was determined through

(D)  spin was determined by

(E)  spin was determined as a result of

这个spin是动词，were也是动词，两个动词在一起。。。这题我知道是靠主谓一致，可是该怎么理解呢？

还有啊，总结了OG10还用总结11th吗？总结真的太费时间了。我总结一体要10几分钟，这样正常吗？？
