Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, "Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?" Tom at once answered, "Your brother. Because electricity travels faster than sound waves." "That's every good," Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. "Yes, Kate." "I disagree," Kate said. "Your brother would hear you earlier because when it's 11 o'clock here it's only 8 o'clock in Los Angeles." Miss Gogers was teaching her class _ . A) how to telephone B) about electricity C) about time zone D) about sound

More Americans are Googling themselves ------ and many are checking out their friends, co-workers and romantic interests, too. In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine. That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised the growth wasn't higher. "Yes it's doubled, but many Internet users have never done this simple act of plugging their name with search engines," she said. Americans under 50 and those with more education and income were more likely to self-Google because their jobs demand a certain online persona. Meanwhile, Pew found that 53 percent of adult Internet users admit looking up information about someone else, not including celebrities. Often, it's to find someone _ have lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common. Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating. In many cases, the search is done to find someone's contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies and divorce proceedings. A similar number have searched for someone else's photo. Few Internet users say they Google themselves regularly ---- about three-quarters of self-searchers say they have done so only once or twice. And most who have done so consider what they find accurate. Pew also found that teens were more likely than adults to restrict who can see their information at an online hangout like Facebook or News Corp's MySpace. How many people have checked others' photos? A) One- fifth B) One-fourth C) One- third D) A half

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... What is likely to happen next? A) The author lost his temper. B) "No. 2" ran out of his patience. C) The author was well-served by "No. 2". D) The author also went to see the dog-fight.
