input question: Question: "Where is Estonia located?"  Context: "Estonia has had a market economy since the end of the 1990s and one of the highest per capita income levels in Eastern Europe. Proximity to the Scandinavian markets, its location between the East and West, competitive cost structure and a highly skilled labour force have been the major Estonian comparative advantages in the beginning of the 2000s (decade). As the largest city, Tallinn has emerged as a financial centre and the Tallinn Stock Exchange joined recently with the OMX system. The current government has pursued tight fiscal policies, resulting in balanced budgets and low public debt."  Answer:???

Question: "When did the 5th Dalai Lama come into the world?"  Context: "Rawski writes that Altan Khan's conversion to the Gelug "can be interpreted as an attempt to expand his authority in his conflict with his nominal superior, Tümen Khan." To further cement the Mongol-Tibetan alliance, the great-grandson of Altan Khan—the 4th Dalai Lama (1589–1616)—was made the fourth Dalai Lama. In 1642, the 5th Dalai Lama (1617–1682) became the first to wield effective political control over Tibet."  Answer:

Q: Question: "What is the name of the island with less territory?"  Context: "The Greco-Egyptian scientist Claudius Ptolemy referred to the larger island as great Britain (μεγάλης Βρεττανίας - megális Brettanias) and to Ireland as little Britain (μικρής Βρεττανίας - mikris Brettanias) in his work Almagest (147–148 AD). In his later work, Geography (c. 150 AD), he gave these islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain."  Answer:
A: Ireland
Question: Question: "What was unique about Gamal's brother's name?"  Context: "Gamal Abdel Nasser was born on 15 January 1918 in Bakos, Alexandria, the first son of Fahima and Abdel Nasser Hussein. Nasser's father was a postal worker born in Beni Mur in Upper Egypt and raised in Alexandria, and his mother's family came from Mallawi, el-Minya. His parents married in 1917, and later had two more boys, Izz al-Arab and al-Leithi. Nasser's biographers Robert Stephens and Said Aburish wrote that Nasser's family believed strongly in the "Arab notion of glory", since the name of Nasser's brother, Izz al-Arab, translates to "Glory of the Arabs"—a rare name in Egypt."  Answer:
Answer: a rare name in Egypt
[Q]: Question: "what vehicle is mentioned?"  Context: "An exception is the United States, where patents filed prior to 8 June 1995 expire 17 years after the publication date of the patent, but application extensions make it possible for a patent to issue much later than normally expected (see submarine patents). The various MP3-related patents expire on dates ranging from 2007 to 2017 in the U.S. Patents filed for anything disclosed in ISO CD 11172 a year or more after its publication are questionable. If only the known MP3 patents filed by December 1992 are considered, then MP3 decoding has been patent-free in the US since 22 September 2015 when U.S. Patent 5,812,672 expired which had a PCT filing in October 1992. If the longest-running patent mentioned in the aforementioned references is taken as a measure, then the MP3 technology will be patent-free in the United States on 30 December 2017 when U.S. Patent 5,703,999, held by the Fraunhofer-Gesellschaft and administered by Technicolor, expires."  Answer:
****
[A]: submarine
Problem: Given the question: Question: "What ultimately controls how long you sleep?"  Context: "The SCN projects to a set of areas in the hypothalamus, brainstem, and midbrain that are involved in implementing sleep-wake cycles. An important component of the system is the reticular formation, a group of neuron-clusters scattered diffusely through the core of the lower brain. Reticular neurons send signals to the thalamus, which in turn sends activity-level-controlling signals to every part of the cortex. Damage to the reticular formation can produce a permanent state of coma."  Answer:
++++++++++++++++++++++++++++++++
The answer is:
The SCN
