I want to know the answer to the following question:
In what region of modern-day France did the Vikings settle?
All the background I'm provided with is that "In 911, the Viking chieftain Rollo (d. c. 931) received permission from the Frankish King Charles the Simple (r. 898–922) to settle in what became Normandy.[Q]". Is that enough to answer the question?
Answer: yes
