B

本题难度不大，找到答案依据不难。

答案依据在第五段。

第五段第二句：

Recordsshowthatearthquakeswerecommonbefore1906.谈到记录显示在1906年前地震十分常见的。

所以本题错误，答案是B。

B.45minutes

C.30minutes

D.10minutes

D

本题有一定难度，需要认真阅读文章。

答案依据在文章第七段。

带着题干信息词回到文章定位。

第七段第一句谈到，每两三天出去散步10到45分钟会对健康有益，回来看选项，很明显，D是近义解释，是答案。

另外后面的句子是倒装语序，就要考虑某些特殊的句式结构。

因此选C。
