what is possible

晚上给儿子念书，读到着一句话“Bot asked Mrs. Percival if it is possible for Philchard to enter the dog show."儿子的问题来了：

what is possible?

possible 就是有可能的。----英汉字典啊，老妈想糊弄过去，赶快读完故事好睡觉。

tell me what is possible. -----看来儿子不买账

possible means something can happen. -----这个解释还凑合吧

what happened?  -----啊，这么问下去可不行

something happened.  ------ 这就叫有问有答，呵呵
