Input: Article: Schwarzenegger became a naturalized U.S. citizen on September 17, 1983. Shortly before he gained his citizenship, he asked the Austrian authorities for the right to keep his Austrian citizenship, as Austria does not usually allow dual citizenship. His request was granted, and he retained his Austrian citizenship. In 2005, Peter Pilz, a member of the Austrian Parliament from the Austrian Green Party, demanded that Parliament revoke Schwarzenegger's Austrian citizenship due to his decision not to prevent the executions of Donald Beardslee and Stanley Williams, causing damage of reputation to Austria, where the death penalty has been abolished since 1968. This demand was based on Article 33 of the Austrian Citizenship Act that states: "A citizen, who is in the public service of a foreign country, shall be deprived of his citizenship, if he heavily damages the reputation or the interests of the Austrian Republic." Pilz claimed that Schwarzenegger's actions in support of the death penalty (prohibited in Austria under Protocol 13 of the European Convention on Human Rights) had indeed done damage to Austria's reputation. Schwarzenegger explained his actions by referring to the fact that his only duty as Governor of California was to prevent an error in the judicial system.

Now answer this question: What year did Austria outlaw the death penalty?

Output: 1968

Input: Article: From 2004 to 2007, the top five U.S. investment banks each significantly increased their financial leverage (see diagram), which increased their vulnerability to a financial shock. Changes in capital requirements, intended to keep U.S. banks competitive with their European counterparts, allowed lower risk weightings for AAA securities. The shift from first-loss tranches to AAA tranches was seen by regulators as a risk reduction that compensated the higher leverage. These five institutions reported over $4.1 trillion in debt for fiscal year 2007, about 30% of USA nominal GDP for 2007. Lehman Brothers went bankrupt and was liquidated, Bear Stearns and Merrill Lynch were sold at fire-sale prices, and Goldman Sachs and Morgan Stanley became commercial banks, subjecting themselves to more stringent regulation. With the exception of Lehman, these companies required or received government support. Lehman reported that it had been in talks with Bank of America and Barclays for the company's possible sale. However, both Barclays and Bank of America ultimately declined to purchase the entire company.

Now answer this question: How many U.S. investment banks significantly increased their financial leverage from 2004 to 2007?

five
