Read the following context and choose the correct option to answer the question. Context: Last month we spent a few wonderful days visiting our friends Rosa and Massimo who live just outside of Trento. It was our third visit to the area (on one of them I snapped up this recipe for persimmon cake), so I feel it's about time to share some our favourite things that we've been shown by locals. Trento is only a four hour drive from Florence passing Bologna and Verona on the way, which could make very good pit stops if you feel the need to, FYI yet it feels a world away in terms of the landscape and the food, from the golden, rolling hills of Tuscany. Cue towering mountains harbouring mushrooms and berries, lush valleys and turquoise lakes, vines grown on pergolas, enormous plates of sauerkraut and polenta in abundant portions, delicious wines and rustic cakes with German names. Trento is the capital of Trentino, an unusual region of Italy because its official languages are Italian and German and it is actually made up of two self-governing provinces and is known as Trentino-Alto Adige or Trentino-Sudtirol. Confused? Since the eighth century, it has been part of the Austro-Hungarian Empire and only a century ago did it become Italian. It is squeezed between Lombardy and the Veneto to the west and southeast and to the north lies Austria and Switzerland. So it is no surprise that many of the food influences come from its neighbours particularly the northern ones. Eating in the region means eating heartily, even in the summer sunshine, we enjoyed abundant portions of canederli (large rustic dumplings made of bread, herbs and meat, ham or cheese in broth), masses of soft, creamy polenta with thinly sliced roast pork or sausage ragu and slow-cooked beans or thick venison steaks, sauerkraut and gnocchi (sometimes made of out of polenta). I think one waiter was highly disappointed that we weren't able to finish our gargantuan plates one hot day on a mountain with a view of the Dolomites. Somehow there was always room for dessert, though adopted from German and Austrian specialties, you can find cakes... Question: When did the author last visit Trento?
