Q: Article: At Japan's Studio Ghibli, which has produced extraordinary animated films since 1985, the best-known figure has always been one of the company's founders, Hayao Miyazaki. But an equally key figure is co-founder Isao Takahata, who has recently made a new feature, The Tale of Princess Kagnya. It is an unforgettable feature with an unusual hand-drawn aesthetic . The title character is a tiny baby girl who appears in a bamboo plant. She is found by a woodcutter, who takes her home and brings her up. He believes the little girl is a princess, and sets about preparing what he regards as a suitable world for her. This original story is the oldest work of fiction in Japan; every child knows it in its simplified folktale form. "It is a fascinating story with elements of wonder, humour, and sorrow,'' Takahata says, "but these three elements are scattered about." The chief challenge for anyone trying to adapt it is that "we are completely unable to comprehend what was in the heart of Princess Kaguya. Because of this, despite its being well known, few people consider it interesting. There have been several attempts at making a film out of the story, but they ended up being abandoned." He was connected with one of these attempts, but no one paid any attention to his concept. "Fifty-five years later, I thought my concept was still appealing, and used it as a basis for turning the story into a feature film." His concept involves the princess's origins, her expectations and her access to "the full range of human emotions". To realize his vision, Takahata says, "I needed to take the extremely individualistic brushwork and key designs of Osamu Tanabe and Kazuo Oga, two brilliantly talented artists, and have them permeate throughout the film. The two of them drew many pictures, but they weren't nearly enough. The most challenging part was to have all the other animation staff copy their styles in a free and easy way." The Tale of Princess Kaguya has been released, and people are saying that the two founders, now in their seventies, have directed their final films. But is it as clear-cut as that? When I ask Takahata about a scene of escape and urgency with a particularly distinctive visual style, he says he had intended to use "this type of rough-drawn, forceful animation, in a project before this film. "That project hasn't been realized yet, but if it comes to pass, this style is essential." A hint, perhaps, there's still more to come.
Answer: Because people are in the dark about the feelings of Princess Kaguya.

Q: Article: When I worked as a waitress in Chicago, US, my coworkers and I would sigh whenever we heard someone with a foreign accent coming into our restaurant. We knew what it meant to serve a non-American: no tip. We would work just as hard as we always did, but we might not get paid. Americans have an unspoken rule about tipping: they give tips to almost everyone who offers them a service of some kind. Americans tip their waiters, barbers and taxi drivers. An appropriate tip is between 15 and 20 percent of the amount charged for the service (But the charge for the tip doesn't appear on the bill. The customer is expected to add it himself/herself.) Tipping less than this sends a message to your waiters that you think they've done a bad job serving you. And to leave no tip at all is simply unacceptable. It's not that American waiters are greedy. In many countries, waiters are paid a salary for their work. They'll earn money even if no one comes into the restaurant. This system offers much more safety for waiters than the American version. In the US, waiters know that a night without customers means a night without pay. Some countries include a tip for waiters - a "service charge" - on the bill itself. Since the tip is included with the other charges, waiters don't need to worry about people forgetting to tip. But in the US, waiters do not receive a salary, and service charges only appear on bills when there are six or more customers at the table. Since almost all American customers are familiar with the system, they know to add a tip without being told. But visitors to the US may expect waiters to be paid a salary, or think that the tip is included on the bill. So much as we waiters loved hearing stories about other places from our foreign customers, we were always nervous when they got ready to leave the restaurant. We were never sure what to expect.

Q: Article: I had five hours in the company of First Great Western(FGW) last weekend, on a train full of passengers, all the way from Cornwall to London. I got to know some of my fellow passengers rather well. Not through talking to them, you understand. There was the youth who was explaining to his friend exactly how he enjoyed a party with his friends last night. Opposite him was a young woman who was very excited to be going to Lanzarote for her summer holiday. And then there was the man who I took to be a car mechanic ; so detailed and technical was his conversation about a second-hand Audi. Everyone had a different, noisy ringtone, and none of the mobile phone conversations I was forced to hear was interesting. By the end of the journey, I was silently complaining about the modern world, and feeling mad with FGW who, at the very moment when our carriage fell silent, would make an announcement about the buffet car (a carriage where food and drinks are sold) either opening or closing. FGW seems to be campaigning against peace and quietness, having removed quiet carriage spaces where passengers were requested not to use mobiles so that their trains could carry more passengers. How so? I cannot understand why FGW takes no notice of passengers like me, who have suffered a lot from hearing endless telephone conversations. I have no interest in the smallest details of others' lives. Making people listen to boring mobile phone conversations should be regarded as a rude act." Every train carriage should, in theory, be quiet. Why can't that be the standard? It is possible to change public custom and practice. It was not so long ago that sidewalks were littered with dog waste:now it's a general rule that dog owners clean it up after their pets. And once we restore peace and quietness to trains, we can then move on and stop people bringing fast food onto them, too.
Answer: From their phone conversations.

A:
How did the author get to know the three passengers?
