根据下列材料，请回答题：
June came and the hay (干草) was almost ready for cutting. On Midsummer's Eve, which was a Saturday, Mr. Jones went into Willington and got so drunk at the Red Lion that he did not come back until midday on Sunday. His men had milked the cows in the early morning and then had gone out chatting without bothering to feed the animals. When Mr. Jones got back, he immediately went to sleep on the living-room sofa with the "News of the World" over his face. When evening came, the animals were still not fed. At last, they could stand no longer. One of the cows broke into the door of the storehouse with her horns and all the animals began to help themselves to the grains.It was just then that Mr. Jones woke up. The next moment he and his four men were in the storehouse with whips in their hands, whipping in all directions. This was more than the hungry animals would bear. Together, though nothing of the kind had been planned beforehand, they jumped upon their masters. Mr. Jones and his men suddenly found themselves being struck with the horns and kicked from all sides. The situation was quite out Of their control. They had never seen these animals act like this before. This sudden rebellion of the creatures, which they were used
to beating and whipping just as they chose, frightened them. After only a moment or two, they gave up trying to defend themselves. A minute later all five of them were in full fright down the road with the animals running after them joyfully. The four men did not feed the cows because __________. A． they had not cut the hay yet
B． M Jones wasn't at home
C． they did not have time to feed them
D． the cows had fed themselves
