Now, solve this: Question: Are olives the largest export in Sassari? Passage:Sassari is located in north-western Sardinia, at above sea level. The area rises up on a wide karstic plateau that slopes gently down towards the Gulf of Asinara and the Nurra plain. The city is surrounded by a green belt of thousands of hectares of olive plantations, which from the 19th century have partly replaced the mixed woodlands of oak and other Mediterranean trees as well as the maquis shrubland. The thinly populated Nurra Plain, located to the west, occupies the main part of the region of Sassari, while the urban agglomeration, with a population of about 275,000 inhabitants, is located to the south east. The abundance of water, with about 400 springs and artesian wells, has made for much development of horticulture over the centuries.
