Text IIAmericans generally consider themselves to be frank, open, and direct in their dealings with other people. In their daily conversation, they may chat with each other in a more direct way. “Let’s lay our cards on the table,” they say. Or, “Let’s stop playing games and get to the point.” Unlike statements from other nations, these and many other phrases show the Americans’ idea that people should clearly state what they think about and what they want.Americans tend to believe that disagreements are best settled by means of long discussions among the people involved. If I dislike something you are doing, I should tell you about it directly so you will know, clearly and from me personally, how I feel about it. They do not prefer to hide their feelings, which may make themselves uneasy. For them, bringing in other people to solve the problem is regarded as somewhat strange. And the former will be looked upon as one who is not brave enough to speak directly to someone else.Americans will often speak openly and directly to others about things they dislike. They will try to do so in a manner they call “constructive”, that is, a manner which the other person will not find offensive or unacceptable. If they do not speak openly about what is in their minds, they will often express their meanings in nonverbal ways (without words, but through facial expressions, body positions, and gestures). They believe it is also a good way to show their feelings.Americans are not taught, as people in many Asian countries are, that they should hidetheir feelings. Their words, the tone of their voices, or their facial expressions will usually reveal when they are feeling angry, unhappy, confused, or happy and satisfied.6. According to the passage, ______________
A. Americans don’t state clearly what they think and wantB. Americans use body language to defend other peopleC. Americans seldom speak openlyD. Americans state clearly what they want
