听力原文: Aid workers in Mozambique say they' re increasingly confident that they are coming to terms with the humanitarian crisis that follows the devastating floods. Helicopters and planes have been working flat-out to get supplies through to areas of need. The World Health Organization has warned that malaria has risen sharply after the flooding. This report from Jim Fish in Maputong: "The skies over Mozambique have never been this busy. Relays of helicopters and aircraft crisscross to and fro ferrying food and supplies to the stricken areas. A fleet of more than 50 aircraft are now operating, averaging 200 flights per day. At one forward supply depot in the town of Pamela, helicopters were arriving every few minutes, ferrying sacks of maize, and rice and beans out to where the flood survivors are congregated. But there are still pockets of people who have not received food or fresh water for over a week."

Then he discovered that an old friend of his was one of the members of the jury at his trial. Of course, he did not tell anybody, but he managed to see his friend secretly one day. He said to him," Jim, I know that the jury will find me guilty of having stolen the money. I cannot hope to be found not guilty of taking it —that would be too much to expect. But I should be grateful to you for the rest of my life if you could persuade the other members of the jury to add a strong recommendation for mercy to their statement that they consider me guilty."
"Well, George," answered Jim," I shall certainly try to do what I can for you as an old friend, but of course I cannot promise anything. The other eleven people on the jury look terribly strong-minded to me."
George said that he would quite understand if Jim was not able to do anything for him and thanked him warmly for agreeing to help.
The trial went on, and at last the time came for the jury to decide whether George was guilty or not. It took them five hours, but in the end they found George guilty, with a strong recommendation for mercy.
Of course, George was very pleased, but he did not have a chance to see Jim for some time after the trial. At last, however, Jim visited him in prison, and George thanked him warmly and asked him how he had managed to persuade the other members of the jury to recommend mercy.
"Well, George," Jim answered," as I thought, those eleven men were very difficult to persuade, but I managed in the end by tiring them out. Do you know, those fools had all wanted to find you not guilty!"
We are told that George expected Jim to help______

A. prove him innocent
B. him turns over a new leaf
C. lighten his punishment
D. him escapes from prison
