根据短文内容，选择正确的答案。
One hot summer day, a fox was walking through a beautiful garden. He hadn't eaten for hours and felt very hungry and thirsty. As he looked around, he noticed a tall vine(藤) growing against a wall. The vine was full of big, purple grapes. They hung in bunches(串), and they looked so juicy and sweet that the fox's mouth began to water.
The fox really wanted to eat those grapes. He stood on his back legs and jumped as high as he could, but he couldn't reach them. He tried again, leaping with all his strength, but his paws(爪子) only touched the air. He stepped back a few paces and ran towards the vine, jumping at the last moment. Still, the grapes were too high. He tried many times until he was completely tired and out of breath.
Finally, the fox gave up. As he walked away, he lifted his head and said loudly, "I'm sure those grapes are sour. They are not worth eating at all."
