I've turned this from giving all of the statements first (which required much scrolling up and down), to several one-from-a-list parts. I think it's easier to work with.

The setup of this question was extraordinarily complicated, with dozens of variables. I've removed basically all of them, and added the random names extension.

It's checkpointed below, should anyone wish to revert to the original.

This was originally "watching grass grow". I have changed the context from 1st to 3rd person and changed grass to a sunflower, which seems a much more likely thing to measure.

Also used the random names extension, and as a result I've changed quite a lot of this, so I'm marking needs to be tested.
