Input: Article: Any individual made a member of the Order for gallantry could wear an emblem of two crossed silver oak leaves on the same riband, ribbon or bow as the badge. It could not be awarded posthumously and was effectively replaced in 1974 with the Queen's Gallantry Medal. If recipients of the Order of the British Empire for Gallantry received promotion within the Order, whether for gallantry or otherwise, they continued to wear also the insignia of the lower grade with the oak leaves. However, they only used the post-nominal letters of the higher grade.

Now answer this question: Who could wear a emblem of two crossed silver oak leaves?

Output: Any individual made a member of the Order for gallantry


Article: A samurai could divorce his wife for a variety of reasons with approval from a superior, but divorce was, while not entirely nonexistent, a rare event. A wife's failure to produce a son was cause for divorce, but adoption of a male heir was considered an acceptable alternative to divorce. A samurai could divorce for personal reasons, even if he simply did not like his wife, but this was generally avoided as it would embarrass the person who had arranged the marriage. A woman could also arrange a divorce, although it would generally take the form of the samurai divorcing her. After a divorce samurai had to return the betrothal money, which often prevented divorces.

Question: How common was divorce for samurai?
Ans: rare


Here is a question about this article: One way of proving that a given disease is "infectious", is to satisfy Koch's postulates (first proposed by Robert Koch), which demands that the infectious agent be identified only in patients and not in healthy controls, and that patients who contract the agent also develop the disease. These postulates were first used in the discovery that Mycobacteria species cause tuberculosis. Koch's postulates can not be applied ethically for many human diseases because they require experimental infection of a healthy individual with a pathogen produced as a pure culture. Often, even clearly infectious diseases do not meet the infectious criteria. For example, Treponema pallidum, the causative spirochete of syphilis, cannot be cultured in vitro - however the organism can be cultured in rabbit testes. It is less clear that a pure culture comes from an animal source serving as host than it is when derived from microbes derived from plate culture. Epidemiology is another important tool used to study disease in a population. For infectious diseases it helps to determine if a disease outbreak is sporadic (occasional occurrence), endemic (regular cases often occurring in a region), epidemic (an unusually high number of cases in a region), or pandemic (a global epidemic).
What is the answer to this question: What is one way of proving that a given disease is infectious?
****
So... satisfy Koch's postulates


The problem: Answer a question about this article:
Activision Blizzard CEO Bobby Kotick has criticized PS3's high development costs and inferior attach rate and return to that of Xbox 360 and Wii. He believes these factors are pushing developers away from working on the console. In an interview with The Times Kotick stated "I'm getting concerned about Sony; the PlayStation 3 is losing a bit of momentum and they don't make it easy for me to support the platform." He continued, "It's expensive to develop for the console, and the Wii and the Xbox are just selling better. Games generate a better return on invested capital (ROIC) on the Xbox than on the PlayStation." Kotick also claimed that Activision Blizzard may stop supporting the system if the situation is not addressed. "[Sony has] to cut the [PS3's retail] price, because if they don't, the attach rates are likely to slow. If we are being realistic, we might have to stop supporting Sony." Kotick received heavy criticism for the statement, notably from developer Bioware who questioned the wisdom of the threatened move, and referred to the statement as "silly."
What company is Kotick the CEO of?
****
The answer: Activision Blizzard


The problem: Answer a question about this article:
After the financial crisis of 2007–08, it was known in 2008–2009 that two Portuguese banks (Banco Português de Negócios (BPN) and Banco Privado Português (BPP)) had been accumulating losses for years due to bad investments, embezzlement and accounting fraud. The case of BPN was particularly serious because of its size, market share, and the political implications - Portugal's then current President, Cavaco Silva, and some of his political allies, maintained personal and business relationships with the bank and its CEO, who was eventually charged and arrested for fraud and other crimes. In the grounds of avoiding a potentially serious financial crisis in the Portuguese economy, the Portuguese government decided to give them a bailout, eventually at a future loss to taxpayers and to the Portuguese people in general.
In what two years was there a financial crisis?
****
The answer:
2007–08
