Question: During the Burgfriedenspolitik, the SPD voted for debt securities that finance what?

full_context: Document 1: Dual Alliance (1879): The Dual Alliance was a defensive alliance between Germany and Austria-Hungary, which was created by treaty on 7 October 1879 as part of Bismarck's system of alliances to prevent or limit war. The two powers promised each other support in case of attack by Russia. Also, each state promised benevolent neutrality to the other if one of them was attacked by another European power (generally taken to be France, even more so after the Franco-Russian Alliance of 1894). Germany’s Otto von Bismarck saw the alliance as a way to prevent the isolation of Germany and to preserve peace, as Russia would not wage war against both empires.
Document 2: Reinsurance Treaty: The Reinsurance Treaty, (June 18, 1887), a secret agreement between Germany and Russia arranged by the German chancellor Otto von Bismarck after the German-Austrian-Russian "Dreikaiserbund" or League of the Three Emperors, collapsed in 1887, because of competition between Austria-Hungary (Franz Joseph I) and Russia (Alexander III) for spheres of influence in the Balkans. The treaty provided that each party would remain neutral if the other became involved in a war with a third great power, though this would not apply if Germany attacked France or if Russia attacked Austria. Bismarck showed the Russian ambassador the text of the German-Austrian alliance of 1879 to drive home the last point. Germany paid for Russian friendship by agreeing to the Russian sphere of influence in Bulgaria and Eastern Rumelia (now part of southern Bulgaria) and by agreeing to support Russian action to keep the Black Sea as its own preserve. When the treaty was not renewed in 1890, a Franco-Russian alliance rapidly began to take shape.
Document 3: The New Freedom: The New Freedom has three meanings. This was Woodrow Wilson's campaign slogan in the 1912 election. The first two comprise the campaign speeches and promises of Woodrow Wilson in the 1912 presidential campaign calling for limited government, and Wilson's 1913 book of the same name. The more common meaning comprises the Progressive programs enacted by Wilson as president during his first term (1913-1916), when the Democrats controlled Congress. Wartime policies are not generally considered part of the New Freedom; and after the 1918 elections the Republicans took control of Congress, and were generally hostile to the New Freedom. As President, Wilson focused on three types of reform:
Document 4: Japanese invasion money: Japanese invasion money, officially known as Southern Development Bank Notes (Japanese: 大東亜戦争軍票 "Dai Tō-A Sensō gunpyō", "Greater East Asia War military scrip"), was currency issued by the Japanese Military Authority, as a replacement for local currency after the conquest of colonies and other states in World War II. In February 1942 in Japan, laws were passed establishing the Wartime Finance Bank and the Southern Development Bank. Both institutions issued bonds to raise funds. The former loaned money primarily to military industries, but also to a wide range of other ventures, including hydroelectric generators, electric power companies, shipbuilding and petroleum. The latter provided financial services in areas occupied by the Japanese military, and Southern Development Bank notes were in fact used as de facto military scrip. In December 1942, the outstanding balance of Southern Development Bank notes stood at more than 470 million; in March 1945, more than 13 billion.
Document 5: Christmas truce: The Christmas truce (German: "Weihnachtsfrieden" ; French: "Trêve de Noël" ) refers to a series of widespread but unofficial ceasefires along the Western Front of World War I around Christmas 1914.
Document 6: Australian government debt: The Australian government debt is the amount owed by the Australian federal government. The Australian Office of Financial Management, which is part of the Treasury Portfolio, is the agency which manages the government debt and does all the borrowing on behalf of the Australian government. Australian government borrowings are subject to limits and regulation by the Loan Council, unless the borrowing is for defence purposes or is a 'temporary' borrowing. Government debt and borrowings (and repayments) have national macroeconomic implications, and are also used as one of the tools available to the national government in the macroeconomic management of the national economy, enabling the government to create or dampen liquidity in financial markets, with flow on effects on the wider economy.
Document 7: United States Treasury security: A United States Treasury security is an IOU from the US Government. It is a government debt instrument issued by the United States Department of the Treasury to finance government spending as an alternative to taxation. Treasury securities are often referred to simply as Treasuries. Since 2012 the management of government debt has been arranged by the Bureau of the Fiscal Service, succeeding the Bureau of the Public Debt.
Document 8: Sovereign credit: Sovereign credit is the credit of a sovereign country backed by the financial resources of that state. Sovereign credit is the opposite of sovereign debt. Fiat money is sovereign credit and sovereign bonds are sovereign debts. When money buys bonds, sovereign credit cancels sovereign debt.
Document 9: National debt of the United States: The national debt of the United States is the amount owed by the federal government of the United States. The measure of the public debt is the value of the outstanding Treasury securities at a point of time that have been issued by the Treasury and other federal government agencies. The terms national deficit and national surplus usually refer to the federal government budget balance from year to year, not the cumulative total. A deficit year increases the debt because more money is spent than is received; a surplus year decreases the debt because more money is received than spent.
Document 10: Zero-coupon bond: A zero-coupon bond (also discount bond or deep discount bond) is a bond bought at a price lower than its face value, with the face value repaid at the time of maturity. Note that this definition assumes a positive time value of money. It does not make periodic interest payments, or have so-called "coupons", hence the term zero-coupon bond. When the bond reaches maturity, its investor receives its par (or face) value. Examples of zero-coupon bonds include U.S. Treasury bills, U.S. savings bonds, long-term zero-coupon bonds, and any type of coupon bond that has been stripped of its coupons.
Document 11: Distressed securities: Distressed securities are securities over companies or government entities that are experiencing financial or operational distress, default, or are under bankruptcy. As far as debt securities, this is called distressed debt. Purchasing or holding such distressed-debt creates significant risk due to the possibility that bankruptcy may render such securities worthless (zero recovery).
Document 12: Separate peace: The phrase "separate peace" refers to a nation's agreement to cease military hostilities with another, even though the former country had previously entered into a military alliance with other states that remain at war with the latter country. For example, at the start of World War I (1914–1918), Russia was a member, with the United Kingdom and France, of the Triple Entente, which went to war with the Central Powers formed by Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. After the fall of Russian monarch Nicholas II and the rise to power of the Bolsheviks, Russia defaulted on its commitments to the Triple Entente by signing a separate peace with Germany and its allies in 1917. This armistice was followed on 3 March 1918 by the formal signing of the Treaty of Brest-Litovsk.
Document 13: War bond: War bonds are debt securities issued by a government to finance military operations and other expenditure in times of war.
Document 14: Treaty of Brest-Litovsk: The Treaty of Brest-Litovsk was a peace treaty signed on 3 March 1918 between the new Bolshevik government of Soviet Russia and the Central Powers (Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire), that ended Russia's participation in World War I. The treaty was signed at Brest-Litovsk (Polish: "Brześć Litewski" ; since 1945 Brest), after two months of negotiations. The treaty was agreed upon by the Bolshevik government under threat of further advances by German and Austrian forces. According to the treaty, Soviet Russia defaulted on all of Imperial Russia's commitments to the Triple Entente alliance.
Document 15: Burgfriedenspolitik: Burgfriedenspolitik (] )—literally "castle peace politics" but more accurately a political policy of "party truce" — is a German term used for the political truce the Social Democratic Party of Germany and the other political parties agreed to during World War I. The trade unions refrained from striking, the SPD voted for war credits in the Reichstag and the parties agreed not to criticize the government and its war. There were several reasons for the "Burgfrieden" politics: the Social Democrats believed it was their patriotic duty to support the government in war; they were afraid of government repression should they protest against the war; they feared living under an autocratic Russian Czar more than the German constitutional monarchy and its Kaiser; and they hoped to achieve political reforms after the war, including the abrogation of the inequitable three-class voting system, by cooperating with the government.
