根据短文回答下列问题。

     Read this dialogue between Karen Lu and Alice Evans on a daily television talk show called  "Our

World". Alice has recently travelled around India on an elephant.

Karen:Welcome to the programme. First of all, Alice, what gave you the idea to travel around India on

an elephant?

Alice:Well, it all started when I went to a photographic exhibition of elephants. Then, a few days later, I

started reading a book about an Englishman travelling all the way to India on foot. I suddenly had the idea

to travel on an elephant.

Karen: So what did you do next?

Alice: I rang a friend in India and told him 1 wanted to buy an elephant. He told me about the prices of

elephants. He said that 1 would need two people to help me: one person to cut the animal's food, because elephants can eat up to 200kg of food each day, and another person to drive the elephant.

Karen:Is it expensive to buy an elephant?

Alice:We bought a female elephant called Tara for about US$6,000.

Karen: Well, Alice, you'd found your elephant. What did you do next?

Alice:Next, we had to plan our route. As we had to sell Tara at the end of the journey, we decided to

travel to Sonepur in northern India where the world's oldest elephant market is located. The market lasts

for two weeks every year and elephants can never be sold there before the special date of 23rd

November. The whole journey would take about 64 days to complete.

Karen:I see. And did you have any problems on your journey?

Alice:Yes. a few, but nothing too serious. At the beginning, Tara hurt her foot. But that got better after a

week. The weather was very bad as well. And we often found uninvited guests in our tents-snakes-which made sleeping rather difficult!

Karen: That sounds awful! And what finally happened when you reached the end of your journey?

Alice: I had grown very fond of Tara, and I didn't want to sell her, even though I knew I had to. Luckily,

however, I met some old friends at the market. They were looking for an elephant for their national park. I knew that Tara would be safe in the national park, so I gave her to them. I was very sad to say goodbye.
