Problem: Airport:

On runways, green lights indicate the beginning of the runway for landing, while red lights indicate the end of the runway. Runway edge lighting consists of white lights spaced out on both sides of the runway, indicating the edge. Some airports have more complicated lighting on the runways including lights that run down the centerline of the runway and lights that help indicate the approach (an approach lighting system, or ALS). Low-traffic airports may use pilot controlled lighting to save electricity and staffing costs.

What may low-traffic airports use to save electricity and staffing costs?
---
A: pilot controlled lighting


Problem: The national postal infrastructure was completely destroyed during the civil war. In order to fill the vacuum, Somali Post signed an agreement in 2003 with the United Arab Emirates' Emirates Post to process mail to and from Somalia. Emirates Post's mail transit hub at the Dubai International Airport was then used to forward mail from Somalia to the UAE and various Western destinations, including Italy, the Netherlands, the United Kingdom, Sweden, Switzerland and Canada.
When was the infrastructure of the postal service destroyed?
---
Answer: during the civil war


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the context of political corruption, a bribe may involve a payment given to a government official in exchange of his use of official powers. Bribery requires two participants: one to give the bribe, and one to take it. Either may initiate the corrupt offering; for example, a customs official may demand bribes to let through allowed (or disallowed) goods, or a smuggler might offer bribes to gain passage. In some countries the culture of corruption extends to every aspect of public life, making it extremely difficult for individuals to operate without resorting to bribes. Bribes may be demanded in order for an official to do something he is already paid to do. They may also be demanded in order to bypass laws and regulations. In addition to their role in private financial gain, bribes are also used to intentionally and maliciously cause harm to another (i.e. no financial incentive).[citation needed] In some developing nations, up to half of the population has paid bribes during the past 12 months.
What do you call paying government officials to use their position in their office?
A: a bribe


Context and question: A definition of "matter" more fine-scale than the atoms and molecules definition is: matter is made up of what atoms and molecules are made of, meaning anything made of positively charged protons, neutral neutrons, and negatively charged electrons. This definition goes beyond atoms and molecules, however, to include substances made from these building blocks that are not simply atoms or molecules, for example white dwarf matter—typically, carbon and oxygen nuclei in a sea of degenerate electrons. At a microscopic level, the constituent "particles" of matter such as protons, neutrons, and electrons obey the laws of quantum mechanics and exhibit wave–particle duality. At an even deeper level, protons and neutrons are made up of quarks and the force fields (gluons) that bind them together (see Quarks and leptons definition below).
What is made out of negatively charged protons?
Answer: unanswerable


Question: As heirs of the Dominican priory of Poissy in France, the Dartford sisters were also heirs to a tradition of profound learning and piety. Sections of translations of spiritual writings in Dartford's library, such as Suso's Little Book of Eternal Wisdom and Laurent du Bois' Somme le Roi, show that the "ghoostli" link to Europe was not lost in the crossing of the Channel. It survived in the minds of the nuns. Also, the nuns shared a unique identity with Poissy as a religious house founded by a royal house. The English nuns were proud of this heritage, and aware that many of them shared in England's great history as members of the noble class, as seen in the next chapter.
Is there an answer to this question: What book could not be found in the Dartford's sister's library?

Answer: unanswerable


QUES: Tito became increasingly ill over the course of 1979. During this time Vila Srna was built for his use near Morović in the event of his recovery. On 7 January and again on 11 January 1980, Tito was admitted to the Medical Centre in Ljubljana, the capital city of the SR Slovenia, with circulation problems in his legs. His left leg was amputated soon afterward due to arterial blockages and he died of gangrene at the Medical Centre Ljubljana on 4 May 1980 at 15:05, three days short of his 88th birthday. His funeral drew many world statesmen. Based on the number of attending politicians and state delegations, at the time it was the largest state funeral in history; this concentration of dignitaries would be unmatched until the funeral of Pope John Paul II in 2005 and the memorial service of Nelson Mandela in 2013. Those who attended included four kings, 31 presidents, six princes, 22 prime ministers and 47 ministers of foreign affairs. They came from both sides of the Cold War, from 128 different countries out of 154 UN members at the time.

What was built near Morovic for Tito to use in the event of his recovery?
What is the answer?
ANS:
Vila Srna
