Q26

In his experiments with gravity, Issac Newton shoed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the others.

A. of all the other planets, each contributing according to their
B. of all the other planets, with each of them contributing according to their
C. all the other planets, each of which contributing according to its
D. all the other planets, each contributing according to its
E. all the other planets, each of which contribute according to their

答案選D
這題答案算是比較沒問題的

可是我對於D的結構有點不了解說,
請問each contributing according to its mass and distance from the others 在整句話裡是當做同位語嗎?

each独立主格形式的典型用法.复数名词,＋each引导的独立主格，强调句末的复数名词.

255 Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seemingly unlimited number of antibodies, each targeted specifically at an invading microbe or foreign substance.

老帖子翻出来了

我想问的是：

all the other planets前为什么不用加of来平行呢,这样不会引起歧义吗？？？

是不是加上of更好呢

谢谢！
