I want to know the answer to the following question:
Which basic topographical area is in western Switzerland?
All the background I'm provided with is that "Switzerland lies between latitudes 45° and 48° N, and longitudes 5° and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss Plateau or Central Plateau, and the Jura mountains on the west.". Is that enough to answer the question?
