Problem: United States dollar:

The monetary base consists of coins and Federal Reserve Notes in circulation outside the Federal Reserve Banks and the U.S. Treasury, plus deposits held by depository institutions at Federal Reserve Banks. The adjusted monetary base has increased from approximately 400 billion dollars in 1994, to 800 billion in 2005, and over 3000 billion in 2013. The amount of cash in circulation is increased (or decreased) by the actions of the Federal Reserve System. Eight times a year, the 12-person Federal Open Market Committee meet to determine U.S. monetary policy. Every business day, the Federal Reserve System engages in Open market operations to carry out that monetary policy. If the Federal Reserve desires to increase the money supply, it will buy securities (such as U.S. Treasury Bonds) anonymously from banks in exchange for dollars. Conversely, it will sell securities to the banks in exchange for dollars, to take dollars out of circulation.

How much did the monetar base value increase to in 2013?

A: over 3000 billion


Problem: In 1952, following a referendum, Baden, Württemberg-Baden, and Württemberg-Hohenzollern merged into Baden-Württemberg. In 1957, the Saar Protectorate rejoined the Federal Republic as the Saarland. German reunification in 1990, in which the German Democratic Republic (East Germany) ascended into the Federal Republic, resulted in the addition of the re-established eastern states of Brandenburg, Mecklenburg-West Pomerania (in German Mecklenburg-Vorpommern), Saxony (Sachsen), Saxony-Anhalt (Sachsen-Anhalt), and Thuringia (Thüringen), as well as the reunification of West and East Berlin into Berlin and its establishment as a full and equal state. A regional referendum in 1996 to merge Berlin with surrounding Brandenburg as "Berlin-Brandenburg" failed to reach the necessary majority vote in Brandenburg, while a majority of Berliners voted in favour of the merger.
When did the German reunification take place?

Answer: 1990


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Over New York City in 1953, Eastern Airlines Flight 8610, a commercial flight, had a near miss with Air Force Flight 8610, a Lockheed C-121 Constellation known as Columbine II, while the latter was carrying President Eisenhower. This prompted the adoption of the unique call sign Air Force One, to be used whenever the president is on board any US Air Force aircraft. Columbine II is the only presidential aircraft to have ever been sold to the public and is the only remaining presidential aircraft left unrestored and not on public display.
What aircraft had an incident with Air Force Flight 8610?
A: Eastern Airlines Flight 8610


Context and question: According to recent estimates, 50% of the population adheres to Christianity, Islam 48%, while 2% of the population follows other religions including traditional African religion and animism. According to a study made by Pew Research Center, 63% adheres to Christianity and 36% adheres to Islam. Since May 2002, the government of Eritrea has officially recognized the Eritrean Orthodox Tewahedo Church (Oriental Orthodox), Sunni Islam, the Eritrean Catholic Church (a Metropolitanate sui juris) and the Evangelical Lutheran church. All other faiths and denominations are required to undergo a registration process. Among other things, the government's registration system requires religious groups to submit personal information on their membership to be allowed to worship.
What percentage of Eritrea is estimated to adhere to Christianity?
Answer: 50%


Question: Oral rehydration solution (ORS) (a slightly sweetened and salty water) can be used to prevent dehydration. Standard home solutions such as salted rice water, salted yogurt drinks, vegetable and chicken soups with salt can be given. Home solutions such as water in which cereal has been cooked, unsalted soup, green coconut water, weak tea (unsweetened), and unsweetened fresh fruit juices can have from half a teaspoon to full teaspoon of salt (from one-and-a-half to three grams) added per liter. Clean plain water can also be one of several fluids given. There are commercial solutions such as Pedialyte, and relief agencies such as UNICEF widely distribute packets of salts and sugar. A WHO publication for physicians recommends a homemade ORS consisting of one liter water with one teaspoon salt (3 grams) and two tablespoons sugar (18 grams) added (approximately the "taste of tears"). Rehydration Project recommends adding the same amount of sugar but only one-half a teaspoon of salt, stating that this more dilute approach is less risky with very little loss of effectiveness. Both agree that drinks with too much sugar or salt can make dehydration worse.
Is there an answer to this question: What can be used to prevent dehydration?

Answer: Oral rehydration solution (ORS)


One adaptation helping both predators and prey avoid detection is camouflage, a form of crypsis where species have an appearance that helps them blend into the background. Camouflage consists of not only color but also shape and pattern. The background upon which the organism is seen can be both its environment (e.g., the praying mantis to the right resembling dead leaves) or other organisms (e.g., zebras' stripes blend in with each other in a herd, making it difficult for lions to focus on a single target). The more convincing camouflage is, the more likely it is that the organism will go unseen.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does a praying mantis use to build its home?
Ah, so..
