Young adults want a wide variety of informational books about aspects of their lives that are new； for example, the physical development of their bodies, the new freedom they have to associate mainly with peers instead of family, and the added responsibilities they feel in deciding what kinds of adult roles they will fit.

[A] Many visitors to different countries don't realize how important it is to understand a country's culture. Sometimes people learn this lesson by making a big cross-cultural blunder, or embarrassing mistake. In business situations, these blunders can cost a lot of money or end business relationships. 

[B] When companies are trying to sell products, it's very important for them to understand what is important to their potential customers, and to understand a bit of their language. For example, one company wanted to sell toothpaste in Southeast Asia. In their advertisement, they claimed that their toothpaste whitened teeth. They didn't understand that many of the local people chewed betel nuts to make their teeth black and that these people thought black teeth were attractive. In another case, a car company tried to sell a car called "Matador" in a Spanish-speaking country. The company thought that it was a strong name because it means "bullfighter." In Spanish, matador is indeed a noun meaning "bullfighter." But it is also an adjective meaning "killing." Imagine driving around in a car called "Killing"! 

[C] Business meetings with people from another country can be very tricky when you don't understand the other country's culture. A European businessman had an important meeting with a company in Taiwan. He wanted to bring gifts for the people he was meeting with. He thought that something with his company's logo on it would be a nice gift. So he bought some very nice pocket knives and had his company's logo printed on them. He didn't know that giving a knife as a gift symbolizes cutting off a friendship! The Taiwanese businessmen were very offended. But luckily, the European businessman was able to repair the relationship with a lot of explanation and apologies. 

[D] It's very easy to make blunders like these people did. But it's also very easy not to. Before you visit a new country, research that country's customs and etiquette (social rules for polite behavior). You can find a lot of information online. Just go to a search engine and type in key words like "cross-cultural etiquette" or "cultural information Taiwan." By spending a few minutes doing research, you can save yourself a lot of embarrassment and make sure you don't accidentally offend anyone.
