Question: Article: A man came home from work late, tired and irritated, to find his 5-year-old son waiting for him at the door. "Daddy, may I ask you a question?" "Yeah sure, what is it?" replied the man. "Daddy, how much do you make an hour?" "That's none of your business. Why do you ask such a thing?" the man said angrily. "I just want to know. Please tell me. How much do you make an hour?" pleaded the little boy. "If you must know, I make $20 an hour." "Oh," the little boy replied, with his head down. Looking up, he said, "Daddy, may I please borrow $10?" The father was furious, "If the only reason you asked that is so you can borrow some money to buy a silly toy or some other nonsense, then you march yourself straight to your room and go to bed. Think about why you are being so selfish. I don't work hard every day for such childish behavior." The little boy quietly went to his room and shut the door. The man sat down and started to get even angrier about the little boy's questions. How dare he ask such questions only to get some money? About an hour or so, the man had calmed down, and started to think: maybe there was something he really needed to buy with that $10 and he really didn't ask for money very often. The man went to the door of the little boy's room and opened the door. "Are you asleep, son?" He asked. "No daddy, I'm awake," replied the boy. "I've been thinking, maybe I was too hard on you earlier," said the man. "It's been a long day and I took out my aggravation on you. Here's the $10 you asked for." The little boy sat straight up, smiling. "Oh, thank you, daddy!" he yelled. Then, reaching under his pillow he pulled out some crumpled up bills. The man, seeing that the boy already had money, started to get angry again. The little boy counted out his money, then looked up at his father. "Why do you want more money if you already have some?" the father grumbled. "Because I didn't have enough, but now I do," the little boy replied. "Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you."

Question: Article: Brownie and Spotty were neighbor dogs who met every day to play together. Like pairs of dogs you can find in any neighborhood, these two loved each other and played together so often that they had worn a path through the grass of the field between their houses. One evening, Brownie's family noticed that Brownie hadn't returned home. They went looking for him with no success. Brownie didn't show up the next day, and, although they made their efforts to find him, by the next week he was still missing, Curiously, Spotty showed up at Brownie's house alone, barking and jumping. Busy with their own lives, they paid no attention to the nervous little neighbor dog. Finally, one morning Spotty refused to take "no" for an answer. Ted, Brownie's owner, was continuously disturbed by the angry, determined little dog. Spotty followed Ted about, barking all the time, then rushing toward a nearby empty lot and back, as if to say, "Follow me! It's urgent!" Eventually, Ted followed Spotty across the empty lot as Spotty stopped to race back and barked encouragingly. The little dog led the man to a deserted spot a half mile from the house. There Ted found his beloved Brownie alive, one of his legs crushed in a steel trap . Frightened, Ted now wished he had taken Spotty's earlier appeals seriously. Then Ted noticed something. Spotty had done something else besides leading Brownie's human owner to his trapped friend. In a circle around the injured dog, Ted found some food remains of every meal. Brownie had been fed that week! Spotty had been visiting Brownie regularly, in the hope of keeping his friend alive. Spotty had actually stayed with Brownie to protect him from hunger and other dangers, and keep his spirits up. Brownie's leg was carefully treated and he soon got well again. For many years thereafter the two families watched the faithful friends chasing each other down that well-worn path between their houses.

Answer: At the very beginning, Ted paid little attention to Spotty because _ .

Question: Article: There's no shortage of web sites offering deals-everything from daily deals to members-only private sales.But when it comes to real jaw-dropping deals, there's one company that seems to have figured out a out a way to really deliver. The company is called QuiBids and they auction the hottest, in-demand electronics like Apple ipads and ipods, as well as other items like gift cards from the top retailers .Unlike other sites, the prices people pay are nowhere near retail.How low are the prices? $33.84 for a new Apple ipad 32 GB(retail $600) $22.10 for a new Nikon D90 Digital SLR Camera(retail $1070) Our first reaction on seeing these prices was disbelief.After all, how cold QuiBids possibly afford to sell these items for so little-surely they must be losing a lot of money. That's where its unique business model comes into play.You see, for every bid a buyer places for an item on QuiBids, the company collects a small fee from the bidder.The fee to bid is only about 60 cents, but based on the volume of sales and bids, the company is able to collect enough to make up for the ridiculous prices the items sell for. But best of all, participating in the QuiBids auction is incredibly fun.Because each each bid costs a little to place, shoppers can strategize when to place their bids.Each auction has a strict time limit.When you place your bid, the system adds a little time to the auction to see if any other bids cone in.If you have the winning bid when the cock runs out-you win the item for that price. But the best part of Quibids may be the "Buy-It-Now"feature.This allows bidders who did not win an auction to still buy the product they want and apply the cost of the bids they placed as a discount on the regular product price. So you still get the item and the bids you placed previously in the auction don't cost you anything!
Answer: how its buying and selling is conducted

Answer:
According to the text , the success of Quibids mainly lies in _ .
