Make responses immediately visible

Hi
In one question of our experiment we ask to generate as many words as possible out of some letters. For example out of ALCNGE they have to create words like ANGEL... etc. They write that in a "fill in the blank". After every word they push "ENTER" and the word disappears and they can write a new one.

Now my question: Is it possible to make their answer visible as soon as they push "ENTER"? So that the fill in the blank and the given responses are presented simultaneously? And how can I do that?

Thanks a lot!
