Article: All things change except barbers, the ways of barbers, and the surroundings of barbers. These never change. What one experiences in a barber's shop the first time he enters one is what he always experiences in barbers' shops afterward till the end of his days. I got shaved this morning as usual. A man approached the door from Jones Street as I approached it from Main--a thing that always happens. I hurried up, but it was of no use; he entered the door one little step ahead of me, and I followed in and saw him take the only empty chair, the one headed by the best barber. It always happens so. I sat down, hoping that I might sit in the chair belonging to the better of the remaining two barbers, for he was a bit ahead. I watched the probabilities with strong interest. When I saw that No. 2 was gaining on No. 1, my interest grew to solicitude . When No. 1 was gradually losing the race, my solicitude rose to anxiety. When No. 1 caught up again, and both were about to finish and say "Next!" first, my very breath stood still with the _ . But when I saw that he had lost the race by a single instant, I rose angrily and quitted the shop, to keep from falling into the hands of No. 2; for I have none of that firmness that enables a man to look calmly into the eyes of a waiting barber and tell him he will wait for his fellow-barber's chair. I stayed out fifteen minutes, and then went back, hoping for better luck. Unfortunately, all the chairs were occupied now, and four men sat waiting, silent, and looking bored, as men always do who are waiting their turn in a barber's shop. I sat down and waited. At last my turn came. A voice said "Next!" and I give in to No. 2, of course. It always happens so. I smiled and said that I was in a hurry, and it affected him as strongly as if he had never heard it. He explored my hair with his claws and suggested that it needed trimming . I said I did not want it trimmed. He explored again and said it was pretty long for the present style. I said I had had it cut only a week before. He stopped for a moment, and then asked "who cut it?" I stared at him from the mirror and replied "You did!". Then a dog-fight attracted his attention, and he ran to the window and stayed and watched it...

Article: This is an excerpt from a speech by Steve Jobs, former CEO of Apple, delivered to graduates of Stanford University on June 12, 2005. I was lucky -- I found what I loved to do early in life. Woz and I started Apple in my parents' garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation -- the Macintosh -- a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge(to be different) and eventually we had _ . When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was destructive. I really didn't know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down. I even thought about running away from the valley . But something slowly began to dawn on me -- I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over. I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. It freed me to enter one of the most creative periods of my life. During the next five years, I started a company named NeXT, another company named Pixar. Pixar went on to create the world's first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple's current renaissance. I'm pretty sure none of this would have happened if I hadn't been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. So keep looking until you find it. Don't settle.
Question: Which of the following is TRUE about Apple?
Options: (A) It rejected one of its founders when he turned 30. (B) It once fell apart due to different visions of the future. (C) NeXT became its parent company and made a great comeback. (D) It has survived after it had a destructive blow.

This summer, something hotter than the weather came to Shanghai. That is the Voice of China. The show soon became a cash cow for the organizer as the advertisement prices reached 1.16 million yuan for 15 seconds. And the show has earned more than 100 million yuan up to now in ad income only, But the organizers' bliss was audiences' melancholy. In the final live show on Sunday, about 14 rounds of advertisements were aired, each of which came at a crucial result-announcing moment. Frequently interrupted by advertisements, some live audience members complained that the show wasn't worth its ticket prices of 180 to 1680 yuan. The planned two and a half hour show went two hours overtime because of the advertising. This annoyed audience members, and touched the nerves of residents living near the site. Someone called the police, and the show is now facing punishment for going over-time and disturbing residents late at night.
