Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 32 to 36.

When you are abroad, you must be careful how you express yourself with your body. If you make your hand into a fist and begin to shake it at somebody, most people will understand that you're angry. But not all actions mean the same in every country. In Asia, people are very careful not to touch anybody with their foot. And, like many other countries, they never put their feet on chairs and tables where they are sitting.
In Fiji, people shake hands for a very long time. Don't worry if this continues for all of your conversation - it's normal. Greetings in some European countries are often quite physical. People kiss friends and family on the cheek and they often hug. In countries like France, what you do at the dinner table is very important. Don't put your elbow on the table, and don't eat with your fingers. People will think you are rude if you do this.
Some countries have different ways of saying 'yes' and 'no'. In Greece and Bulgaria, people shake their head for yes and nod for no. This can be confusing, so it's probably better to learn the words for yes and no. However, there is one international expression that everybody understands. If you are having problems and you don't know what to say, the best thing to do is smile.
