问题
The planets were formed as a result of______.
Certain meteorites lack water and other volatile elements probably because______.
选项
A、these elements are not suitable to exist in these meteorites
B、these elements are lost during the medical changes during collision
C、their crest and cover have been stripped off
D、they are planetoid remnants
答案
B
解析
推理判断题。根据题目找出第五段最后一句与此有关:"也许这可以说明为什么某些陨石上没有水和其他挥发性元素"。追溯本源,前面讲到这些陨石是那些碰撞物体的残留物。第三、四段也都与此有关,第三段提到"They undergo tremendous shearing and gravitational forces that can cause them to fracture into smaller pieces or melt, causing chemical changes in the material and loss of water or other volatile compounds."(碰撞物发生了一系列变化,分成小块、融合,发生化学变化致使水和其他挥发性成分丢失。)因此最根本的根源在于此。
