You already have the answers for these three quesions, but the locations where the hints can be found are missing. To complete this missing information (I use the numbers of your walkthrough at http://gamesolutions.efzeven.nl/soviet-unterzogersdorf-sektor-2-walkthrough-monochrom2009/):
4. You’re the product of the workforce
You’re beloved without remorse
To the future you gave birth
Now you upgrade planet Earth.

We are working on an idea.
(from the room with two fallen statues - just behind the room with the wrench)
Comment: I must confess that this one is quite tricky in english, as the translation differs in both variants. The statue says "We're spinning this idea..." and the question is "We are working on _______". Where as in german both sentences are "Wir arbeiten an einer __Idee__". I changed the sentence on the statue for future releases, as it is text without voice output and thus quite simple to change.
