Input: Read this: The undergraduates have a number of traditions: Painting The Rock (originally a fountain donated by the Class of 1902) is a way to advertise, for example, campus organizations, events in Greek life, student groups, and university-wide events. Dance Marathon, a 30-hour philanthropic event, has raised more than 13 million dollars in its history for various children's charities. Primal Scream is held at 9 p.m. on the Sunday before finals week every quarter; students lean out of windows or gather in courtyards and scream. Armadillo Day, or, more popularly, Dillo Day, a day of music and food, is held on Northwestern's Lakefill every Spring on the weekend after Memorial Day. And in one of the University's newer traditions, every year during freshman orientation, known as Wildcat Welcome, freshmen and transfer students pass through Weber Arch to the loud huzzahs of upperclassmen and the music of the University Marching Band.
Question:  What name is sophomore orientation known as?

Output: unanswerable


QUES: A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase, SAP HANA, and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language.[disputed – discuss] Sometimes a DBMS is loosely referred to as a 'database'.

What does DBMS stand for?
What is the answer?
ANS: database management system


QUES: For decades after the Second World War, any national symbol or expression was a taboo. However, the Germans are becoming increasingly patriotic. During a study in 2009, in which some 2,000 German citizens age 14 and upwards filled out a questionnaire, nearly 60% of those surveyed agreed with the sentiment "I'm proud to be German." And 78%, if free to choose their nation, would opt for German nationality with "near or absolute certainty". Another study in 2009, carried out by the Identity Foundation in Düsseldorf, showed that 73% of the Germans were proud of their country, twice more than 8 years earlier. According to Eugen Buss, a sociology professor at the University of Hohenheim, there's an ongoing normalisation and more and more Germans are becoming openly proud of their country.
What war was followed by an increase in national symbols?

ANS: unanswerable


Integral to the story of the origin of the name "Antarctica" is how it was not named Terra Australis—this name was given to Australia instead, and it was because of a mistake made by people who decided that a significant landmass would not be found farther south than Australia. Explorer Matthew Flinders, in particular, has been credited with popularizing the transfer of the name Terra Australis to Australia. He justified the titling of his book A Voyage to Terra Australis (1814) by writing in the introduction:
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What book did Flinders write in 1841?
Ah, so.. unanswerable


Question: When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a primary role in determining which mechanism will occur. When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent. This is called a substitutional alloy. Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal. The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix. Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.
Try to answer this question if possible: What is the name of one interstitial alloy?
Answer: Steel


Input: Read this: PAL, SECAM and NTSC frame rates technically apply only to analogue standard definition television, not to digital or high definition broadcasts. However, with the roll out of digital broadcasting, and later HDTV broadcasting, countries retained their heritage systems. HDTV in former PAL and SECAM countries operates at a frame rate of 25/50 Hz, while HDTV in former NTSC countries operates at 30/60 Hz.
Question: PAL, SECAM, and NTSC frame rates do apply to what broadcasts?

Output:
unanswerable
