PROBLEM: Passage: There were an estimated 140,000 cases of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) reported in 2003, and an estimated 1.9 percent of the adult population was afflicted with HIV/AIDS that year, among the lowest rates in Sub-Saharan Africa (see also HIV/AIDS in Africa).

Life expectancy at birth is 60.3 years (58.2 years among males and 62.5 years among females) (2017 est.).

PROBLEM: Passage: In an attempt to take the castle, Itakura Shigemasa was killed. More shogunate troops under Matsudaira Nobutsuna, Itakura's replacement, soon arrived. However, the rebels at Hara Castle resisted the siege for months and caused the shogunate heavy losses. Both sides had a hard time fighting in winter conditions. On February 3, 1638, a rebel raid killed 2,000 warriors from the Hizen Domain. However, despite this minor victory, the rebels slowly ran out of food, ammunition and other provisions. By April 1638, there were over 27,000 rebels facing about 125,000 shogunate soldiers. Desperate rebels mounted an assault against them on April 4 and were forced to withdraw. Captured survivors and the fortress' rumored sole traitor, Yamada Emosaku, revealed the fortress was out of food and gunpowder. On April 12, 1638, troops under the command of the Kuroda clan of Hizen stormed the fortress and captured the outer defenses. The rebels continued to hold out and caused heavy casualties until they were routed on April 15. 
Question: In what year was Itakura Shigemasa killed? 
Answer type: Date 

SOLUTION: {'day': '', 'month': '', 'year': '1637'}.

PROBLEM: Passage: Lower than expected population figures from the census suggest that Karachis poor infrastructure, law and order situation, and weakened economy relative to other parts of Pakistan made the city less attractive to in-migration than previously thought. The figure is disputed by all the major political parties in Sindh. Karachis population grew by 59.8% since the 1998 census to 14.9 million, while Lahore city grew 75.3% – though Karachis census district had not been altered by the provincial government since 1998, while Lahores had been expanded by Punjabs government, leading to some of Karachis growth to have occurred outside the citys census boundaries. Karachis population had grown at a rate of 3.49% between the 1981 and 1998 census, leading many analysts to estimate Karachis 2017 population to be approximately 18 million by extrapolating a continued annual growth rate of 3.49%. Some had expected that the citys population to be between 22 and 30 million, which would require an annual growth rate accelerating to between 4.6% and 6.33%. 
Question: How many years was the time span where Karachis populations has grown at a rate of 3.49%? 
Answer type: Number 

SOLUTION:
17.
