By what means did they get the information?这里的what可以换成which吗?为什么呢
不能.因为在这里是“什么途径”的意思.
which和what的区别是:前者用于选择范围较小或较明确的场合,后者用于选择范围较大或不明确的场合.
which 的选择范围相对比较小或明确,所以其后一般不接else,但却常与表特定范围的of短语连用:
  Which of the three girls is the oldest?这三个女孩中哪个年纪最大?
  Which of the boys is the strongest?这些男孩当中,哪一个力气最大?
  你还要点别的什么吗?
  正:What else would you like?
  误:Which else would you like?
  四、口语中的用法区别
  比较以下三组对话,注意体会它们的区别:
  A:Who is he?他是谁?
  B:He is Mary’s husband.他是玛丽的丈夫.
  注:Who is he?的意思是要了解他的一些情况.
  A:What is he?他是干什么的?
  B:He is an English teacher.他是英语教师.
  注:What is he?的意思是询问他的职业.
  A:Which is he?哪位是他?
  B:The one by the window.窗户边的那位.
  注:Which is he?的意思是要在几个人中辨别要找的人.
