If `S == 1`, this outputs:

> One side of a square is 1 1 long. What is its area?

If `S == 2`, you get:

> One side of a square is 2 units long. What is its area?

As it turns out this exercise never selects `S` such that `S == 1`, so this doesn't technically break anything, but I'm curious how it happened to get like this and if there's somewhere else this same bug snuck in that we haven't caught.
