Problem: Switzerland:

Swiss are fans of football and the national team is nicknamed the 'Nati'. The headquarters of the sport's governing body, the International Federation of Association Football (FIFA), is located in Zürich. Switzerland hosted the 1954 FIFA World Cup, and was the joint host, with Austria, of the Euro 2008 tournament. The Swiss Super League is the nation's professional club league. For the Brasil 2014 World Cup finals tournament, the country's German-speaking cantons will be closely monitored by local police forces to prevent celebrations beyond one hour after matches end. Europe's highest football pitch, at 2,000 metres (6,600 ft) above sea level, is located in Switzerland and is named the Ottmar Hitzfeld Stadium.

What is the nickname for the Swiss national football team?

A: Nati


Problem: Matte solder is usually fused to provide a better bonding surface or stripped to bare copper. Treatments, such as benzimidazolethiol, prevent surface oxidation of bare copper. The places to which components will be mounted are typically plated, because untreated bare copper oxidizes quickly, and therefore is not readily solderable. Traditionally, any exposed copper was coated with solder by hot air solder levelling (HASL). The HASL finish prevents oxidation from the underlying copper, thereby guaranteeing a solderable surface. This solder was a tin-lead alloy, however new solder compounds are now used to achieve compliance with the RoHS directive in the EU and US, which restricts the use of lead. One of these lead-free compounds is SN100CL, made up of 99.3% tin, 0.7% copper, 0.05% nickel, and a nominal of 60ppm germanium.
The HASL finish encourages oxidation from what?

According to the Crisis Group, since Myanmar transitioned to a new government in August 2011, the country's human rights record has been improving. Previously giving Myanmar its lowest rating of 7, the 2012 Freedom in the World report also notes improvement, giving Myanmar a 6 for improvements in civil liberties and political rights, the release of political prisoners, and a loosening of restrictions. In 2013, Myanmar improved yet again, receiving a score of five in civil liberties and a six in political freedoms
What is the current rating of for Burma from the  Freedom in the World report and what caused the current standing ?
A: Myanmar improved yet again, receiving a score of five in civil liberties and a six in political freedom


Context and question: Investment in the telecom industry is held to be one of the clearest signs that Somalia's economy has continued to develop. The sector provides key communication services, and in the process facilitates job creation and income generation.
What are key communication services?
Answer: unanswerable


Question: The committee considered an eight-bit code, since eight bits (octets) would allow two four-bit patterns to efficiently encode two digits with binary-coded decimal. However, it would require all data transmission to send eight bits when seven could suffice. The committee voted to use a seven-bit code to minimize costs associated with data transmission. Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.:217, 236 § 5 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.
Is there an answer to this question: Why did the company decide on 9bit instead?

Answer: unanswerable


QUES: The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium. The sinoatrial node uses calcium to cause a depolarizing signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers. The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body. Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight.

Where is the heart contained in the avian circulatory system?
What is the answer?
