sentences from inside my head

I am doing Ukrainian on duolingo and reading The Night Stages and in bed last night trying to go to sleep I came up with this sentence, which I assume in the compounding of these two things:

Who can say how Ludmila Petrovna got her bicycle into the work camp.

Pleased with myself this morning waking up and remembering it, as well as getting the patronymic correct.

Now if only I knew something more about how this sentence fits into a story, I’d be set. I still haven’t got my last duolingo inspired sentence:

All the men have two red hats;

(which was one of the sentences duolingo kept making me translate to English from German: Alle Männer haben zwei rote Hüte) into a story either. Mélange peut-être (to add a third language in there)?

I don’t know anything anymore, if I ever did before.
