I can't overcome it. It asks me to find a word on specific page in specific line, but regardless of my efforts, i can't handle such an easy task. Sometimes it even asks me to find a word on a page with a picture only. I dunno, maby provided manual doesn't match the version of the game or something?

Download the "reference cards" next to the game download in your GOG account. The words you need are in there.

Ok, thanks.

UPD: it worked

For future reference (any one else finding this thread with the same question), they're all in this thread.
