Questions & Answers about Het onderzoek wordt door de deskundige gecontroleerd.
Since the current lesson focuses on prepositions like 'volgens' and 'namens', why is 'door' used here?
In a passive sentence like this, door (by) introduces the person actually performing the action. If you used volgens de deskundige, it would mean 'according to the expert' implying someone else is doing the checking. If you used namens de deskundige, it would mean someone else is checking it 'on behalf of' the expert.
Why does the Dutch sentence use 'wordt' (becomes) when the English translation says 'is'?
Is 'deskundige' a noun or an adjective here?
It acts as a noun here, but it comes from the adjective deskundig (knowledgeable). In Dutch, you can easily turn an adjective into a person by adding an -e and putting de in front of it. Another common example is de zieke (the sick person).
Why is the word 'gecontroleerd' at the very end of the sentence?
