[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.
[A]: B

[Q]: Article: We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution. The 16-year old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic bags degrade in as few as 3 months, a finding that won him first prize at the Canada-Wide Science Fair, a $10 000 prize, a $20 000 scholarship, and a chance to revolutionize a major environmental issue. Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms . If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions. With this goal in mind, he ground plastic bags into a powder and concocted a solution of household chemicals, yeast and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks. The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide. "Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself." said Daniel Burd.
Question: Daniel Burd won first prize at the Canada-Wide Science Fair because _ .
Options: (A) he found a new kind of microorganism (B) he contributed much to environmental protection (C) he found a way to degrade plastics in shorter time (D) he could encourage microbes growth in an easier way
