Have you ever seen the size of elephant's poo?
And who do you think cleans up after the elephant,
not to mention all the other animals in the zoo?
The zookeeper, of course!
大家好，
請問一下，
1.這裡的"seen"是"知道(see)"的意思嗎?!
2."after" 是
(a)跟隨著 think 的片語(think after, 意為"想到"!)，還是
(b)自成一個介詞，為"在..之後"的意思?! (而think後省略"that"?!)
因為如果是(b)，感覺有點像中翻英(：跟在大象的屁股後)，覺得有點不可思議！！
