When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure--and so soon--that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead--take me away” when it is dead.

But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

请阅读下列寓言小故事和故事寓意,从所给的六个选项( A、B、C、D、E和F)中,选出附和各小题要求的最佳选项
下面是几则寓言小故事:
46. An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, aiming at the dove. The ant, perceiving his design, stung him in the foot. In pain the birdcatcher shouted, and noise made the dove take wing.
47. Two men were travelling together, when a bear suddenly met them on their path. One of them climbed up quickly into a tree and hid himself in the branches. The other, seeing that he must be attacked, fell flat on the ground, and when the bear came up and felt him with his snout, and smelt him all over, he held his breath, and pretended to be dead as much as he could. The bear soon left him, for he will not touch a dead body. When he disappeared, the other traveler descended from the tree, and asked his friend what it was the bear had whispered in his ear. “He gave me this advice,” his companion replied. “Never travel with a friend who deserts you at the approach of danger.”
48. A prince had some monkeys trained to dance. Being naturally good at learning, they showed themselves excellent pupils, and in their rich clothes and masks, they danced as well as any of the courtiers. Their performance was often repeated with great applause, till on one occasion a courtier, bent on mischief, took from his pocket a handful of nuts and threw them upon the stage. The monkeys at the sight of the nuts forgot their dancing and became (as indeed they were) monkeys instead of actors. Pulling off their masks and tearing their robes, they fought with one another for the nuts. The dancing spectacle thus came to an end in the laughter and ridicule of the audience.
49. A cock was once strutting up and down the farmyard among the hens when suddenly he noticed something shining in the straw. “Ho! Ho!” said he, “that’s for me,” and soon rooted it out from beneath the straw. It turned out to be a pearl that by some chance had been lost in the yard. “You may be a treasure,” signed the cock, “to man, but for me I would rather have a single barley-corn.”
50. An old man on the point of death summoned his sons around hi to give them some parting advice. He ordered his servants to bring in a bunch of sticks, and said to his eldest son: “Break it.” The son tried hard, but with all his efforts was unable to break the bundle. The other sons also tried, but none of them was successful. “Untie it,” said the father, “and each of you take a stick.” When they had done so, he called out to them: “Now, break,” and each stick was easily broken.
