why not 'Post quintam horam coquit Stephanus cibum'?
Looks like an acceptable variant to me. I hope you reported it.
I know not all the audio fields are populated, but it's weird to do this as a click-on-the-words exercise and to suddenly, in the middle of things, have a voice yell, "STEPHANUS!"
I answered "Post quintam horam coquit Stephanus cibum."
It counted it wrong.
Why not "Post quintam horam cibum Stephanus coquit"?
