I want to know the answer to the following question:
Would linguistic differences make it difficult or easy to point out someone who moved from a different region of the Netherlands?
All the background I'm provided with is that "These separate grammar rules are a lot more difficult to imitate correctly than simple sound shifts, making it easy to recognise people who didn't grow up in a certain region, even decades after they moved.". Is that enough to answer the question?
Answer: yes
