Question 17 is based on the passage you have just heard.

  Body language, especially gestures, varies among cultures. For example, a nod of the head means "yes" to most of us. (16) But in Bulgaria and Greece a nod means "no" and a shake of the head means "yes". Likewise, a sign for OK, forming a circle with our forefinger and thumb, means zero in France and money in Japan. (17) Waving or pointing to an Arab business person would be considered rude because that is how Arabs call their dogs over. Folded arms signal pride in Finland, but disrespect in Fiji. The number of bows that the Japanese exchange on greeting each other, as well as the length and the depth of the bows, signals the social status each party feels towards the other. Italians might think you're bored unless you use a lot of gestures during discussions. (18) Many American men sit with their legs crossed with one ankle resting over the opposite knee. However, this would be considered an insult in Muslim countries, where one would never show the sole of the foot to a guest. Likewise, Americans consider eye contact very important, often not trusting someone who is afraid to look you in the eye. But in Japan and many Latin American countries, keeping the eyes lowered is a sign of respect. To look upon firmly in the eye is considered a sign of ill breeding and is felt to be annoying.

(17). What is likely to offend Arab business people?

解析：D。本题为细节题。问题为：什么可能会冒犯阿拉伯商人？根据原文“Waving or pointing to an Arab business person would be considered rude because that is how Arabs call their dogs over.”可知向阿拉伯人挥手或用手指指他们是粗鲁的，故正确答案选D。
