Q: Article: A recent report says we spend an average of two hours and 40 minutes each day looking at a smartphone. That doesn't mean making calls, but using apps and browsing the Web. Spend that amount of time staring at anything. Checked our email in a restaurant, shared a picture of the food when it arrived, or checked a fact during a conversation only to be drawn into reading more instead of contributing verbally. It's no secret our lives are being affected by our obsession with smartphones. However, never before has this phenomenon been displayed so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10. 5 million times. Ironically, YouTube's statistics show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phone. The short film, written by and starring actress Charlene deGuzrnan, shows groups of people in various social situations, the majority of which are completely attracted by their phones instead of the world around them. It's depressing because we' ve all seen it, and sad because to a certain extent, we all do it.

Q: Article: China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities. First, you must be punctual with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late! It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surprised if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have "dress down Friday", when people wear casual clothes. In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names. In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business! So, use these tips, and you will be on your way to a successful international business career!
Answer: White.

A: Which color should you NOT wear when meeting a person from the USA?

Q: Article: Whether it is Mozart or Miley, your choice of music could determine whether you will perform well at your job. A new study suggests that listening to music in the office improves the speed and accuracy of tasks such as data entry, proofreading and problem solving. In an officebased experiment, 88 per cent of participants were found to produce their most accurate work when listening to music. The study also found that 81 per cent completed their work fastest when music was played. And it matters what type of music you listen to. For instance, if you're doing your tax returns, then classical music is the most effective as it improves maths skills. Listening to Jessie J or Justin Bieber could also improve your speed, with 58 per cent of participants completing data entry tasks faster while listening to pop songs. During proofreading, dance music, such as David Guetta, had the biggest positive impact with participants increasing their speed by 20 per cent compared to tests undertaken with no music at all. Dance music also had a positive effect on spellchecking with a 75 per cent pass rate compared to 68 per cent when no music was played at all. The research, undertaken by Brightonbased Mindlab International, suggests that silent offices may be the least productive. The Music Works experiment revealed a positive correlation between music and productivity. Overall, it showed that when listening to music, nine out of ten people performed better, said Dr David Lewis, chairman of Mindlab International.
Answer: The music of Mozart.
