Problem: Guinea-Bissau has started to show some economic advances after a pact of stability was signed by the main political parties of the country, leading to an IMF-backed structural reform program. The key challenges for the country in the period ahead are to achieve fiscal discipline, rebuild public administration, improve the economic climate for private investment, and promote economic diversification. After the country became independent from Portugal in 1974 due to the Portuguese Colonial War and the Carnation Revolution, the rapid exodus of the Portuguese civilian, military, and political authorities resulted in considerable damage to the country's economic infrastructure, social order, and standard of living.

Question: Neptune has a planetary ring system, though one much less substantial than that of Saturn. The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. The three main rings are the narrow Adams Ring, 63,000 km from the centre of Neptune, the Le Verrier Ring, at 53,000 km, and the broader, fainter Galle Ring, at 42,000 km. A faint outward extension to the Le Verrier Ring has been named Lassell; it is bounded at its outer edge by the Arago Ring at 57,000 km.
Is there an answer to this question: Where is Johns ring from the center of Neptune?

Answer: unanswerable


Question: Five major climatic regions are found in Nepal. Of these, Kathmandu Valley is in the Warm Temperate Zone (elevation ranging from 1,200–2,300 metres (3,900–7,500 ft)), where the climate is fairly temperate, atypical for the region. This zone is followed by the Cool Temperate Zone with elevation varying between 2,100–3,300 metres (6,900–10,800 ft). Under Köppen's climate classification, portions of the city with lower elevations have a humid subtropical climate (Cwa), while portions of the city with higher elevations generally have a subtropical highland climate. In the Kathmandu Valley, which is representative of its valley's climate, the average summer temperature varies from 28–30 °C (82–86 °F). The average winter temperature is 10.1 °C (50.2 °F).
Is there an answer to this question: How many significant climate regions exist in Nepal?

Answer:
Five
