Answer 1

你的句子 好像 不完整
原句是 Amid rumors that there were prehistoric mammoths wandering around the unknown
region and that somewhere in its wilds was a mountain of rock salt 80by 45miles in extent,the two captains set out.
Amid rumors是介词短语作状语 后面that引导的是同位语从句 第二个 that从句 是并列的同位语从句 其中 这是倒装句 somewhere in its wilds是从句中的表语 was 是系动词
a mountain of rock salt 80by 45miles in extent是主语
其中 80by 45miles in extent是定语 修饰a mountain of rock salt
后面是主句 two captains 是主语 set out是谓语.

句子主干 Amid rumors，the two captains set out.
句子意思 当时有一些传言 说有史前的猛犸在这一陌生的区域活动 而且在这一陌生区域的某个地方 有一巨大的盐石山 其面积达80英里长 45英里宽 ，就在这些传言中 两位上尉出发了 。
