I'm taking a test and have to guess the right answer to the question after the article. Article: For nearly 250 years, Debrett's has advised the British public on suitable social manners. Now, it has listed modern guide to good manners, answering the questions that most trouble the British public in 2014. Using mobile phone in public More questions are asked about mobile use than any other case. According to Debrett's, it is always rude to pay more attention to a phone than the people around you, and they should always be put away when you're paying for something in a shop. They should be turned off in theatres, cinemas or any space where silence is required. Smoking e-cigarettes at work As electronic cigarettes become more popular, questions about whether they are acceptable in the workplace are asked more often. According to Debrett's, they should never be used in a work environment. Smoking e-cigarettes at work shows that you're not focused on your work and may also have a bad influence on your workmates. Giving up your seat on public transport In a recent university experiment only 20 per cent of London tube passengers are willing to give up their seat to people in need. According to Debrett's, passengers should always offer to give up their seat to any person that is pregnant, elderly, or clearly in need. It is important to remember, however, that it is just as impolite to rudely refuse the offer of a seat as it is to not offer a seat. Eating before everyone is served The final question is one that we've all asked ourselves: is it rude to start eating at the table before everyone else has been served? According to Debrett's, the simple answer is yes, unless the host or hostess _ dinners to start. Question: How many questions about good manners are listed in the passage? Options: A: 250. B: 2014.
