有句句子唔識改呀=\/=[Help`]

Firstly, a woodchuck土撥鼠 is also known as a groundhog (have a look at the link below to see info of a woodchuck)
http://en.wikipedia.org/wiki/Woodchuck

Chuck describes a movement of throwing something quickly across a short distance (chuck = 抛/扔)

So... the question:;
How much wood would the woodchuck chuck if the woodchuck could chuck wood
is asking 如果土撥鼠能扔木頭的wa, 它可以扔多少木頭le??

Indirect question format:
Can you explain how much wood can a woodchuck chuck, if it can chuck wood??

Hope it helps~
