Read the passage below carefully and evaluate the statement that follows.
For generations, the bi-annual Azalai camel caravans traversing the Ténéré desert to the salt pits of Bilma served as more than a transport route for salt slabs; they constituted a vital economic ecosystem for remote oasis settlements along the corridor. Oasis residents relied on trading livestock fodder, dates, and well water to thousands of camel drivers during their seasonal stopovers, providing these isolated communities with nearly all their annual liquidity. However, over the past two decades, the introduction of heavy diesel trucks has largely supplanted the traditional camel herds, compressing what was once a three-week journey into a three-day haul. While urban salt merchants in Niamey praise the trucks for drastically reducing spoilage and transit delays, rural oasis settlements have seen their local economies collapse. Bereft of the steady foot traffic and trade of the caravans, young oasis dwellers are increasingly forced to migrate to urban centers in search of wage labor.
Statement: The primary driver of rural-to-urban migration among youth in the Ténéré oasis settlements is the economic disruption caused by the shift in desert transport modes rather than changes in salt extraction methods.
