When we meet people for the first time，we often make decisions about them based entirely on how they look. And, of course it's something that works both ways, for we too are being judged on our appearance. When we look good, we feel good, which in turn leads to a more confident and self-assured manner. People then pick up on this confidence and respond positively towards us. Undoubtedly，what's insideis important，but sometimes we can send out the wrong signals simply by wearing inappropriate clothing or not spending enough time thinking about how others see us.

上一段作者就个人品位问题作了一番论述，并就如何发现个人品位给了一些建议。在个人品位已经确定的基础上，接下来的事情就是挑选和尝试了。与上面提到的段落不同的是本段的段落主旨句不在句首而在句尾。作者以颜色为例告诉读者，虽然尝试一些新的东西是件不错的事情，但应该注意不要走极端。细心的考生在本段可以发现一个同义词组try out和challenge，前者是尝试的意思，一般指尝试某种新事物，后者为挑战的意思，也可用于指对未知的事物做出的尝试。而且这两个词与选项B中的experiment意思相近，experiment一种解释为“试验”，另一种解释就是“尝试”。在本段最后一句话中，还出现了 takecare 一词，与[B]项中的cautious相呼应。因此B选项为最佳答案。
