Input: Consider Input: Article: What would you do if your pet cat died just before Christmas? Many cat lovers would go out and buy another cat. But one American woman was unable to bear life without her much loved pet cat Nicky. He had been with her for 17 years; and when she knew he was going to die, she had him cloned. Little Nicky was cloned by an American company, called GSC. But the new cat cost his owner $50,000. "He is the same. His characteristics are the same," the woman told news reporters. The company, Sausalito-based Genetic Savings and Clone, made her available to speak to reporters only on condition that her name or hometown was not used. The woman said she feared being the target of groups against cloning. "Nicky loved water, which is an unusual characteristic of cats. Little Nicky jumped into my bath. Most cats are afraid of water, but Little Nicky is different: he loves it, just like my old cat," said the woman, who said she was in her early 40s and worked in the airline industry. The company delivered Little Nicky two weeks ago and was expected to publicly announce the news on Thursday. However, the cat's creation has raised heated debate. Many people have said they felt disgusted at the amount of money spent on cloning a cat. They said that she should have chosen one of the many cats without a home -- cats like this are a common problem in many countries. The woman has only told news reporters her first name, Julia, but she has already received nearly 100 frightening letters from angry people, who say that cloning is against nature. Little Nicky was not only expensive, but also, like all cloned animals, may have more health problems than an animal which was born in the usual way. GSC said it had to try 80 times before it succeeded in producing a cloned cat. The company is now using new techniques and soon they hope to produce cloned dogs as well as cats. GSC said that if people were not happy with the cloned cats or dogs, they could have their money back. At the moment the cost of cloning is very high, but the manager of CSC said he hoped that eventually it would go down, and that in five years, the cost should be $20,000 for a dog or $10,000 for a cat.
Answer: Because other cats are afraid of water.

Output: Why did Julia have her cat Nicky cloned?

Input: Consider Input: Article: It was an extremely hot day. My younger brother Walt and I had decided to go swimming in a deep swimming hole across Mr. Blickez's farm and through some woods, because it would be the only way to cool ourselves down. The only problem with our plan was that this farm was guarded by a huge mean Hereford bull . Mr. Blickez had told us that Elsie was the meanest bull in town, maybe even in the county and we believed in him. But the hotter it got, the more we thought there was something _ about what he said. For one thing, we remembered Mr. Blickez liked telling tall tales; for another, Elsie seemed like a strange name for a bull. Finally, I talked Mom into asking permission for us to walk through the farm, and Mr. Blickez agreed. On our way across the farm, we stopped at the fence to admire the swimming hole. The sun shone brightly across the cool waters. We couldn't wait to get there. Suddenly, Walt shouted loudly. Elsie had run to him and was licking his back. I immediately hid under the fence. However, when I looked up, I saw that Elsie wasn't a big mean bull at all. She was just a friendly young cow, and she was going to keep licking my brother's back as long as he stood still. When we discovered the truth, we were so happy. We then ran to the swimming hole and jumped in. The water was just as wonderful as we had dreamed. After that day, we had many good days and we often visited our secret swimming hole guarded by the so-called "big mean bull". .
Answer: They had to face a very mean bull.
