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，
请问一下，
1.这里的"seen"是"知道(see)"的意思吗?!
2."after" 是
(a)跟随着 think 的词组(think after, 意为"想到"!)，还是
(b)自成一个介词，为"在..之后"的意思?! (而think后省略"that"?!)
因为如果是(b)，感觉有点像中翻英(：跟在大象的屁股后)，觉得有点不可思议！！
