Style thing: I find the following easier to read and also easier to maintain because you don't have to worry so much about the Array indexes:

```Javascript
"Welcome to MAMA. To give U the best information possible we need " +
"to ask U a few questions. Are U pregnant, or do U have a baby?",
[
        new Choice("pregnant", "Pregnant"),
        new Choice("baby", "Baby"),
        new Choice("dontknow", "Don't Know"),
]

```
