在一次鼓励创新的报告会上，有位学者出一道题。 ○△ 四个图形符号中，哪一个与其他三个类型不同？有人说圆形，因为圆形是惟一没有角的图形；也有人说三角形，它是惟一由直线构成的；又有人说半圆形也正确，它是惟一由直线和曲折组成的；最后有人说，第四个图形也可，因为这是惟一非对称性的图形。看来，由于标准和角度的不同，这四个图形都可以作为正确答案。

    的确，世界是千变万化的，疑问是层不出穷的，答案是丰富多彩的。在生活中，看问题的角度、对问题的理解、解决问题的方法以及问题的答案不止一个的事例很多。你有这样的经历、体验、见闻和认识？

请以“答案是丰富多彩的”为话题写一篇文章。

注意：①这个话题的范围是很宽泛的，只要与学者的这道题引发的思想感受有关，都符合要求。②文体不限。可以记叙经历，编述故事，抒发感情，发表议论，展开想像，等等。③题目自拟。④不少于800字。
