In Colombia , there are some unwritten rules that people are used to , These rules are not officially established , but people do respect them . For example , on a bus , a person keeps a distance from another person , and people don't like to touch each other . Many people come to work late because they prefer to wait for another bus if the first one is too crowded . They don't want to have to stand too close to another person , or maybe they are afraid of starting a conversation . A friend of mine in Colombia once said his mom got angry because he came home late , so he asked her , " Mom , what do you think of most people arriving at their jobs so late ? " That gave her the answer to her question since everyone knows no one wants to get on a bus that is too crowded . His mother realized at that moment that customs have a big influence on a person's life . Sometimes , people don't like to make any kind of conversation or make eye contact with others . For example , when they are in line at a bank , they prefer to look up or down rather than look at other people . Moreover , people usually look down when they are in an elevator . Not only on a bus , in line at a bank , and in an elevator do people usually avoid talking to other people , but also in the streets when they are walking , they prefer to look down and to avoid contact with others . When people in Colombia are in line at banks , they _ . A) make eye contact B) look at other people C) make conversation D) look up or down

The idea of micropayments--- charging Web users tiny amounts of money for single pieces of online content--- was basically put to sleep toward the end of the dot-com boom. In December 2000, Clay Shirky, a professor in New York University's interactive telecommunications program , wrote a manifesto that people still quote whenever someone suggests using the idea. "Micropayments will never work," he wrote, mainly because "users hate them." But wait. Without many people noticing, micropayments have arrived--- just not in the way they were originally imagined. The 99 cents you pay for a song on the Internet is a micropayment. So are the tiny amounts that some operators of small web sites can earn whenever someone clicks on the ads on their pages. Some stock-photography companies sell pictures for as little as $1 each. "Micropayments are here" said Benjamin M. Companie, a lecturer atprefix = st1 /NortheasternUniversity, "they just have not developed in the way that everybody expected." From the earliest days of the Web until around the time of Mr Shirky's manifesto, the expectation was that a handful of companies would provide platforms---or perhaps a single platform--- that would enable Web users to pay a penny or a dollar for a bit of content such as a newspaper article, or a research report. Simply clicking a link would complete the transaction . Sellers of content--- at the time, newspaper companies---were among the most interested in the idea as they looked for tax income that didn't depend on advertising. You will have to pay for it, if you _ . A) visit some famous websites B) read latest news on the internet C) advertise for your products on some websites D) download your favorite songs

Q: How do you feel after you've stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes. Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown. In a similar way, new research suggests that a gene calledperiod3affects how well you function without sleep. The discovery adds to older evidence thatperiod3helps determine whether you like to stay up late or get up early. Theperiod3gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you. Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies ofperiod3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers. Results showed that the people with the short form ofperiod3performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off. People with the longperiod3gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form. Which of the following statements about theperiod3 is wrong? A) It affects whether you like to stay up late or get up early. B) It comes in two forms: short and long. C) One has either two longs or two shorts of it. D) Your parents determine what particular combination you have.
A: C
