[EX Q]: 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."

[EX Q]: Article: Every year, as Spring Festival draws near, most Chinese people will get excited to make preparation for the most important festival and make plan for the winter break. It is a little like Christmas in the United States, but there are some differences between the two festivals. Both the major Chinese and the major Western holidays come during the cold season, and special food is expected. In western countries, cookies and cakes begin just after Thanksgiving in November and show up everywhere. Turkey, potatoes and other food come later. Similar thing happens in China. Entering lunar December, most families will make shopping plans for _ and food is certainly one of the most important things to be considered. At the end of the month, both parents in each family will be very busy---the father is busy buying food while the mother is busy cooking. A deeper similarity is tradition. Christmas, as the letters "Christ" suggests, began as a holiday to celebrate the birthday of Jesus Christ. Many people pray on this day. In China, people living in cities or towns, though they don't plan to sow seeds this month, still celebrate on the big day for farmers. Followers of both holidays are also different from each other. While Chinese people travel to the homes of elder relatives, Americans usually call or send cards. Westerners prefer Christmas carols to fireworks. In Christmas, many family gifts come together instead of one by one, since adults may have only one day free to celebrate. But the most curious difference is about students. Chinese students going home for Spring Festival sometimes report that they get bored by the end of vacation, yet American students seldom get bored around Christmas and western New Year. Not everyone enjoys classic holiday traditions. Students in western countries may get upset, as too much homework, travel or bad family relations may destroy the short holiday season. In China, more and more college students choose to travel or work during the winter holiday instead of going home to stay with their families. It's against the tradition but many people accept it.
Question: What does the writer mainly want to tell us in this passage?
Options: (A) Food in different festivals. (B) Differences between two festivals. (C) Festivals in China and western countries. (D) Traditional celebrations in different countries.
[EX A]: B
