请大家帮忙看看这道题！我的思路不是很清晰

tiny quantities of more than thirty rare gases ,most of them industrial by-products,threaten to warm the earth's atmosphere even more rapidly than carbon dioxide during the next fifty years.

答案是    to warm the earth's atmosphere ecen more rapidly ocer the next fifity years than carbon dioxide will

我做这个题的时候思路不清晰，从一开始找进行比较的主体就错了，不知道大家有没有什么好方法。晴指点

那里的题？怎么不贴出整个题目呢？

这题应该补出谓语（或主动词），否则会产生歧义。你的答案应该是对的。

噢 先谢了哈  这是 LZM上面的题

我选错了  我选的是  a warming of the earth's atmosphere during the next fifty years even more rapid than carbon dioxide's

我做的时候很矛盾 因为前一个比较主体的核心词tiny quantities嘛，我就觉得后面的应该跟她可比嘛，可我觉得把tiny quantities作为 比较的中心也不对，但是最后还是选了个稍微与tiny quantities of more than thirty rare gases 靠谱的就选了这个 carbon dioxide's
