关於TPO8 RUNNING WATER ON MARS 的第六题,我也挺困惑的...
我一看A就觉得部队,文章明明说的是Flooding shaped the outflow channels approximately 3 billion years ago, about the same times as the 【northern volcanic plains formed】,怎麼能说是the same time that 【volcanic activity was occurring on the northern plains.】呢,平原形成时间不代表火山活动的时间呀...

答案和解析
其实这种考题不仅考对文章的了解,还考一些地理常识吧.
你可以查一下 northern volcanic plains formed 是不是由于 volcanic activity
如果说火山活动导致平原形成,那么这个选项是正确的.
另外,the same times as the 【northern volcanic plains formed】,这里火山平原形成, TIME不是指时间点, 是XXX大约出现在3亿年前, 大约就是northern volcanic plains 形成的时候.
希望能帮助你理解.做这样的题,还是用排除法好些.
