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 many times a year does the Federal Reserve Bank meet?

A: unanswerable


Problem: A UCLA research study published in the June 2006 issue of the American Journal of Geriatric Psychiatry found that people can improve cognitive function and brain efficiency through simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives. This study examined 17 subjects, (average age 53) with normal memory performance. Eight subjects were asked to follow a "brain healthy" diet, relaxation, physical, and mental exercise (brain teasers and verbal memory training techniques). After 14 days, they showed greater word fluency (not memory) compared to their baseline performance. No long term follow up was conducted, it is therefore unclear if this intervention has lasting effects on memory.
What can a person do to increase their brain efficiency?

Answer: simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction

Context and question: Nintendo was not as restrictive as Sega, which did not permit third-party publishing until Mediagenic in late summer 1988. Nintendo's intention, however, was to reserve a large part of NES game revenue for itself. Nintendo required that they be the sole manufacturer of all cartridges, and that the publisher had to pay in full before the cartridges for that game be produced. Cartridges could not be returned to Nintendo, so publishers assumed all the risk. As a result, some publishers lost more money due to distress sales of remaining inventory at the end of the NES era than they ever earned in profits from sales of the games. Because Nintendo controlled the production of all cartridges, it was able to enforce strict rules on its third-party developers, which were required to sign a contract by Nintendo that would obligate these parties to develop exclusively for the system, order at least 10,000 cartridges, and only make five games per year. A 1988 shortage of DRAM and ROM chips also reportedly caused Nintendo to only permit 25% of publishers' requests for cartridges. This was an average figure, with some publishers receiving much higher amounts and others almost none. GameSpy noted that Nintendo's "iron-clad terms" made the company many enemies during the 1980s. Some developers tried to circumvent the five game limit by creating additional company brands like Konami's Ultra Games label; others tried circumventing the 10NES chip.
 What year wasn't there a shortage of DRAM and ROM chips?
Answer: unanswerable


Question: For guidance in practical application of Jewish law, the majority of Orthodox Jews appeal to the Shulchan Aruch ("Code of Jewish Law" composed in the 16th century by Rabbi Joseph Caro) together with its surrounding commentaries. Thus, at a general level, there is a large degree of uniformity amongst all Orthodox Jews. Concerning the details, however, there is often variance: decisions may be based on various of the standardized codes of Jewish Law that have been developed over the centuries, as well as on the various responsa. These codes and responsa may differ from each other as regards detail (and reflecting the above philosophical differences, as regards the weight assigned to these). By and large, however, the differences result from the historic dispersal of the Jews and the consequent development of differences among regions in their practices (see minhag).
Is there an answer to this question: What do Orthodox Jews turn to for guidance and practical application of jewish law?

Answer: Shulchan Aruch


Problem: Muammar Gaddafi:

A Misratan militia took Gaddafi prisoner, beating him, causing serious injuries; the events were filmed on a mobile phone. A video appears to picture Gaddafi being poked or stabbed in the rear end "with some kind of stick or knife" or possibly a bayonet. Pulled onto the front of a pick-up truck, he fell off as it drove away. His semi-naked, lifeless body was then placed into an ambulance and taken to Misrata; upon arrival, he was found to be dead. Official NTC accounts claimed that Gaddafi was caught in a cross-fire and died from his bullet wounds. Other eye-witness accounts claimed that rebels had fatally shot Gaddafi in the stomach; a rebel identifying himself as Senad el-Sadik el-Ureybi later claimed responsibility. Gaddafi's son Mutassim, who had also been among the convoy, was also captured, and found dead several hours later, most probably from an extrajudicial execution. Around 140 Gaddafi loyalists were rounded up from the convoy; tied up and abused, the corpses of 66 were found at the nearby Mahari Hotel, victims of extrajudicial execution. Libya's chief forensic pathologist, Dr. Othman al-Zintani, carried out the autopsies of Gaddafi, his son and Jabr in the days following their deaths; although the pathologist initially told the press that Gaddafi had died from a gunshot wound to the head, the autopsy report was not made public.

What son of Gaddafi, present in the convoy, was found dead shortly after being captured?
---
A:
Mutassim
