Why does a commuter(持火车月票的乘客) always look as if he has just been through a war？ Here is a story of a commuter.
Mr. Green gets up very early every day and eats a quick breakfast. Then he makes his wife drive him to the station. He arrives on time, but his train doesn't. When it finally comes, he squeezes on and finds there are no more seats. He has to stand with his bag between his knees. There is simply no room to put it down. Suddenly a cold wind hits him in the face. The window is broken! He remembers this summer. At that lime the same window didn't even open.
The conductor makes his way through the crowd and asks for the commuter's ticket. The ticket, of course, is buried deep in the poor man's breast pocket. He digs for it. The conductor waits impatiently.
Finally the train reaches the city. Mr. Green is already worn out. He says to himself, "My God, I feel as if I've been through a war!"
If Mr. Green had got up several minutes later, he ______.

A. would have missed the train
B. might still have been able to catch the train
C. wouldn't be sad
D. would have been away from a war
