Scientists associated with BYU have created some notable inventions. Philo T. Farnsworth, inventor of the electronic television, received his education at BYU, and later returned to do fusion research, receiving an honorary degree from the university. Harvey Fletcher, also an alumnus of BYU, inventor of stereophonic sound, went on to carry out the now famous oil-drop experiment with Robert Millikan, and was later Founding Dean of the BYU College of Engineering. H. Tracy Hall, inventor of the man-made diamond, left General Electric in 1955 and became a full professor of chemistry and Director of Research at BYU. While there, he invented a new type of diamond press, the tetrahedral press. In student achievements, BYU Ad Lab teams won both the 2007 and 2008 L'Oreal National Brandstorm Competition, and students developed the Magnetic Lasso algorithm found in Adobe Photoshop. In prestigious scholarships, BYU has produced 10 Rhodes Scholars, four Gates Scholars in the last six years, and in the last decade has claimed 41 Fulbright scholars and 3 Jack Kent Cooke scholars.
Which BYU college was founded by former alumnus Harvey Fletcher?

Problem: Please answer a question about the following article about Geography of the United States:
The east coast Appalachian system, originally forest covered, is relatively low and narrow and is bordered on the southeast and south by an important coastal plain. The Cordilleran system on the western side of the continent is lofty, broad and complicated having two branches, the Rocky Mountain System and the Pacific Mountain System. In between these mountain systems lie the Intermontaine Plateaus. Both the Columbia River and Colorado River rise far inland near the easternmost members of the Cordilleran system, and flow through plateaus and intermontaine basins to the ocean. Heavy forests cover the northwest coast, but elsewhere trees are found only on the higher ranges below the Alpine region. The intermontane valleys, plateaus and basins range from treeless to desert with the most arid region being in the southwest.
What originally covered the east coast of the Appalachians?
A: forest

Question: Read this and answer the question

The high-speed observation deck elevators accelerate to a world-record certified speed of 1,010 metres per minute (61 km/h) in 16 seconds, and then it slows down for arrival with subtle air pressure sensations. The door opens after 37 seconds from the 5th floor. Special features include aerodynamic car and counterweights, and cabin pressure control to help passengers adapt smoothly to pressure changes. The downwards journey is completed at a reduced speed of 600 meters per minute, with the doors opening at the 52nd second.

This speed holds what record?
Answer: world-record certified speed

Problem: The university is the major seat of the Congregation of Holy Cross (albeit not its official headquarters, which are in Rome). Its main seminary, Moreau Seminary, is located on the campus across St. Joseph lake from the Main Building. Old College, the oldest building on campus and located near the shore of St. Mary lake, houses undergraduate seminarians. Retired priests and brothers reside in Fatima House (a former retreat center), Holy Cross House, as well as Columba Hall near the Grotto. The university through the Moreau Seminary has ties to theologian Frederick Buechner. While not Catholic, Buechner has praised writers from Notre Dame and Moreau Seminary created a Buechner Prize for Preaching.
Where is the headquarters of the Congregation of the Holy Cross?
The answer is the following: Rome

Input: Article: Valencia is a bilingual city: Valencian and Spanish are the two official languages. Spanish is official in all of Spain, whereas Valencian is official in the Valencian Country, as well as in Catalonia and the Balearic Islands, where it receives the name of Catalan. Despite the differentiated denomination, the distinct dialectal traits and political tension between Catalonia and the Valencian Country, Catalan and Valencian are mutually intelligible and are considered two varieties of the same language.
Valencian has been historically repressed in favour of Spanish. The effects have been more noticeable in the city proper, whereas the language has remained active in the rural and metropolitan areas. After the Castille-Aragon unification, a Spanish-speaking elite established itself in the city. In more recent history, the establishment of Franco's military and administrative apparatus in Valencia further excluded Valencian from public life. Valencian recovered its official status, prestige and use in education after the transition to democracy in 1978. However, due to industrialisation in recent decades, Valencia has attracted immigration from other regions in Spain, and hence there is also a demographic factor for its declining social use. Due to a combination of these reasons, Valencia has become the bastion of anti-Catalan blaverism, which celebrates Valencian as merely folkloric, but rejects the existing standard which was adapted from Catalan orthography.
Spanish is currently the predominant language in the city proper but, thanks to the education system, most Valencians have basic knowledge of both Spanish and Valencian, and either can be used in the city. Valencia is therefore the second biggest Catalan-speaking city after Barcelona. Institutional buildings and streets are named in Valencian. The city is also home to many pro-Valencian political and civil organisations. Furthermore, education entirely in Valencian is offered in more than 70 state-owned schools in the city, as well as by the University of Valencia across all disciplines.

Now answer this question: How many official languages does Valencia have?

Output:
two
