Task: Question Generation
Input (English): Passage: Paraguay has a small tourism industry. Total tourism receipts declined annually from 2000 through 2002. In 2003 Paraguay's hotel occupancy rate was 38 percent. It increased by 15 percent in 2004. Small gains in tourism have come from business rather than leisure travellers. For many years, Paraguay served as a central market for trafficable, duty-free goods. However, crackdowns by the governments of Brazil and Argentina have stemmed the flow of shoppers travelling to Paraguay looking for trafficable items. Paraguay is a country that has a lot of different activities for tourism, due to privileged weather and location conditions condensed into a varied geography, an inviting "warm" tropical climate and an  interesting history and unmatched folk art that adorn its streets with an identity that enchants anyone who visits the country. As an example, for less than 80 US dollars a visitor can have a personalized trip to a nature reserve area called Eco-Reserva Mbatovi which is located in the Paraguari department, about an hour away from the capital. The trip includes a bunch of different outdoor activities, water, and complete professional guidance during the whole trip.
Output (English): How many years did the tourism receipts annually decline in Paraguay?
