Then draw a rectangle the same size as this text box, and set a trigger
animation so that the answer box becomes visible only when the rectangle is
clicked.
You'll have to send the rectangle to behind the text box so that the text
box is visible when the rectangle is clicked, and also making the rectangle
the same color as the slide background will make it look better.
In addition to the other ways, just draw a rectangle over the words
you want to "blank out" and fill the rectangle with the background
color. Animate the rectangle to exit on click, then it will look like
the word appeared.
For an even better look, you can add a line drawn at the bottom of the
rectangle to represent a "blank", group it with the rectangle and
animate as above.
