Input: Consider Input: Article: Students often want to practice their English outside class. One of the best ways to practice your English is to speak to a foreigner. You may ask, "Is it okay to try to talk to foreigners I see in the street?" The answer is yes and no, but probably no! If you see a foreigner who looks lost, it is polite to ask him, "May I help you?" But, otherwise, you should probably let them get on with their business. Situations, however, do exist where it is quite all right to talk to foreigners. If a foreigner enters your school, classroom, office, shop or restaurant, for instance, feel free to ask him (for example): -- What is your name? -- Where do you come from? -- What do you think of Beijing? -- How long will you stay in Beijing? There are also situations where it's okay to talk to foreigners in public places. If you see a foreigner alone in a restaurant, bar or coffee shop, it may be appropriate to ask him or her: -- Is this seat free? -- Do you mind if I talk to you in English? You can probably help them if they are new in China and if they are alone, you may be able to make them feel more welcome. After a few such questions, you should know whether this person wants to talk to you or not. If they ask you similar questions, or if they give long, informative answers, you're in luck. If not, then give them their privacy. Talking to strangers is fun if you choose the right time and place.

Input: Consider Input: Article: The round-the-clock availability that cell phones have brought to people's lives may be _ amily life, a new study suggests. The study, which followed more than 1300 adults over 2 years, found that those who consistently used a mobile phone through out the study period were more likely to report negative "spillover" between work and home life--and, in turn, less satisfaction with their family life. Spillover(,) actually means that the line between work and home began to become unclear. Work life may invade home life--when a parent is taking job-related calls at home, for instance--or family issues may start to take up work time. For example, a child may call Mom at work, telling her "the microwave exploded", explained Noelle Chesley, an assistant professor of society at the University of Wisconsin Milwaukee and the author of the study. The problem with cell phones seems to be they are allowing for ever more spillover between work and home. This may be especially true for working women, the study found. Among men, consistent use of mobile phones seemed not to allow more work issues to creep into family time. But for women, the spillover tended to go in both directions--being "connected" means that work cuts into home time, and family issues come into work life. Cell phones seem to be opening more lines for stressful exchange among family members. But there may be ways to control the spillover, according to Chesley. Employers, she said, should look at their policies on contacting employees after working hours to make sure their expectations are "reasonable". For their part, employees can decide that cell phones go off during family time, Chesley said.

Options: (A) Cell phones offer 24-hour availability. (B) Cell phones get life and work mixed. (C) Women don't use cell phones in an effective way. (D) Men are better at dealing with family problems.

Output: B
