Problem: Unicode:

In terms of the newline, Unicode introduced U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR. This was an attempt to provide a Unicode solution to encoding paragraphs and lines semantically, potentially replacing all of the various platform solutions. In doing so, Unicode does provide a way around the historical platform dependent solutions. Nonetheless, few if any Unicode solutions have adopted these Unicode line and paragraph separators as the sole canonical line ending characters. However, a common approach to solving this issue is through newline normalization. This is achieved with the Cocoa text system in Mac OS X and also with W3C XML and HTML recommendations. In this approach every possible newline character is converted internally to a common newline (which one does not really matter since it is an internal operation just for rendering). In other words, the text system can correctly treat the character as a newline, regardless of the input's actual encoding.

How does the newliine normallization format work?

A: every possible newline character is converted internally to a common newline


Problem: The Museo Soumaya, named after the wife of Mexican magnate Carlos Slim, has the largest private collection of original Rodin sculptures outside Paris. It also has a large collection of Dalí sculptures, and recently began showing pieces in its masters collection including El Greco, Velázquez, Picasso and Canaletto. The museum inaugurated a new futuristic-design facility in 2011 just north of Polanco, while maintaining a smaller facility in Plaza Loreto in southern Mexico City. The Colección Júmex is a contemporary art museum located on the sprawling grounds of the Jumex juice company in the northern industrial suburb of Ecatepec. It is said to have the largest private contemporary art collection in Latin America and hosts pieces from its permanent collection as well as traveling exhibits by leading contemporary artists. The new Museo Júmex in Nuevo Polanco was slated to open in November 2013. The Museo de San Ildefonso, housed in the Antiguo Colegio de San Ildefonso in Mexico City's historic downtown district is a 17th-century colonnaded palace housing an art museum that regularly hosts world-class exhibits of Mexican and international art. Recent exhibits have included those on David LaChapelle, Antony Gormley and Ron Mueck. The National Museum of Art (Museo Nacional de Arte) is also located in a former palace in the historic center. It houses a large collection of pieces by all major Mexican artists of the last 400 years and also hosts visiting exhibits.
Who is the Museo Soumaya named after?

Answer: the wife of Mexican magnate Carlos Slim


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Other supportive evidence includes: a ≥20% difference in peak expiratory flow rate on at least three days in a week for at least two weeks, a ≥20% improvement of peak flow following treatment with either salbutamol, inhaled corticosteroids or prednisone, or a ≥20% decrease in peak flow following exposure to a trigger. Testing peak expiratory flow is more variable than spirometry, however, and thus not recommended for routine diagnosis. It may be useful for daily self-monitoring in those with moderate to severe disease and for checking the effectiveness of new medications. It may also be helpful in guiding treatment in those with acute exacerbations.
What is not as stable as prednisone for a routine diagnosis?
A: unanswerable


Context and question: Healthcare is funded by the government, undertaken by one resident doctor from South Africa and five nurses. Surgery or facilities for complex childbirth are therefore limited, and emergencies can necessitate communicating with passing fishing vessels so the injured person can be ferried to Cape Town. As of late 2007, IBM and Beacon Equity Partners, co-operating with Medweb, the University of Pittsburgh Medical Center and the island's government on "Project Tristan", has supplied the island's doctor with access to long distance tele-medical help, making it possible to send EKG and X-ray pictures to doctors in other countries for instant consultation. This system has been limited owing to the poor reliability of Internet connections and an absence of qualified technicians on the island to service fibre optic links between the hospital and Internet centre at the administration buildings.
From where are the five resident nurses from?
Answer: unanswerable


Question: Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.
Is there an answer to this question: Lamps and light fixtures  are a form of what?

Answer: Lighting


Problem: Houston:

METRO began light rail service on January 1, 2004, with the inaugural track ("Red Line") running about 8 miles (13 km) from the University of Houston–Downtown (UHD), which traverses through the Texas Medical Center and terminates at NRG Park. METRO is currently in the design phase of a 10-year expansion plan that will add five more lines. and expand the current Red Line. Amtrak, the national passenger rail system, provides service three times a week to Houston via the Sunset Limited (Los Angeles–New Orleans), which stops at a train station on the north side of the downtown area. The station saw 14,891 boardings and alightings in fiscal year 2008. In 2012, there was a 25 percent increase in ridership to 20,327 passengers embarking from the Houston Amtrak station.

When did Houston start using light rail lines?
