Referring to multiple objects in Arrays

I'm experimenting with a q/a application in Flash. Textfield is showing a question. Another inputfield is below for answering. When answering with text, an unformulated sentence can be correct, but not according to what the code expects. In that case I want to write down many different versions of the answer. Questions arrive from an Array. Another Array tells the answer.

For example

var questions:Array = new Array;

questions[0] =  ("How many cars");

answer:Array = new Array;

answer[0] = ("one", "1", "One", "ONE")

The case:

In a function where an if statement is waiting for the inputfield to have the correct answer, how does one write the code?

Example:

(...) function submit (MouseEvent) {

          if      (inputField == ?) {}

          else  {trace("wrong")}

     }

Posted via phone, my computer with the actual code doesn't have internet... Should have uploaded the code I know...
