B．the moon formed from pieces of rock from Mars
C．the pieces from Mars came together to form. the earth
D．the moon is made up of materials similar to those of the earth请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：D
解析：本题为细节题，解题的关键在于“Today most scientists believe that the moon formed from the earth．”。其后内容全部用于说明“huge pieces of the earth”，因此，选项D为正确答案。选项A中所给信息在原文中的表述是“perhaps”，因此与原文不符。选项B中所说“pieces of rock from Mars”原文中没有提及，而原文第三段唯一提到“pieces”的是“huge pieces of the earth broke off”，所以大多数科学家相信的是地球经撞击有碎片脱落，而不是火星。
