In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: When did the first world war occur?, Context: The war has been described as the first "world war", although this label was also given to various earlier conflicts like the Eighty Years' War, the Thirty Years' War, the War of the Spanish Succession and the War of the Austrian Succession, and to later conflicts like the Napoleonic Wars. The term "Second Hundred Years' War" has been used in order to describe the almost continuous level of world-wide conflict during the entire 18th century, reminiscent of the more famous and compact struggle of the 14th century.
[A]: 18th century

[Q]: What was AFL not?, Context: In October 2008, Tom Benson announced that the New Orleans VooDoo were ceasing operations and folding "based on circumstances currently affecting the league and the team". Shortly thereafter, an article in Sports Business Journal announced that the AFL had a tentative agreement to sell a $100 million stake in the league to Platinum Equity; in exchange, Platinum Equity would create a centralized, single-entity business model that would streamline league and team operations and allow the league to be more profitable. Benson's move to shut down the VooDoo came during the Platinum Equity conference call, leading to speculation that he had folded because of the deal.
[A]: profitable

[Q]: What is the most common cause of death from infectious disease?, Context: Tuberculosis is the second-most common cause of death from infectious disease (after those due to HIV/AIDS). The total number of tuberculosis cases has been decreasing since 2005, while new cases have decreased since 2002. China has achieved particularly dramatic progress, with about an 80% reduction in its TB mortality rate between 1990 and 2010. The number of new cases has declined by 17% between 20042014. Tuberculosis is more common in developing countries; about 80% of the population in many Asian and African countries test positive in tuberculin tests, while only 510% of the US population test positive. Hopes of totally controlling the disease have been dramatically dampened because of a number of factors, including the difficulty of developing an effective vaccine, the expensive and time-consuming diagnostic process, the necessity of many months of treatment, the increase in HIV-associated tuberculosis, and the emergence of drug-resistant cases in the 1980s.
[A]:
those due to HIV/AIDS
