Problem: Queen (band):

In 1963, the teenage Brian May and his father custom-built his signature guitar Red Special, which was purposely designed to feedback. Sonic experimentation figured heavily in Queen's songs. A distinctive characteristic of Queen's music are the vocal harmonies which are usually composed of the voices of May, Mercury, and Taylor best heard on the studio albums A Night at the Opera and A Day at the Races. Some of the ground work for the development of this sound can be attributed to their former producer Roy Thomas Baker, and their engineer Mike Stone. Besides vocal harmonies, Queen were also known for multi-tracking voices to imitate the sound of a large choir through overdubs. For instance, according to Brian May, there are over 180 vocal overdubs in "Bohemian Rhapsody". The band's vocal structures have been compared with the Beach Boys, but May stated they were not "much of an influence".

What was the name of Brian May's signature guitar?

A: Red Special

Problem: Today, computer security comprises mainly "preventive" measures, like firewalls or an exit procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network, such as the Internet, and can be implemented as software running on the machine, hooking into the network stack (or, in the case of most UNIX-based operating systems such as Linux, built into the operating system kernel) to provide real time filtering and blocking. Another implementation is a so-called physical firewall which consists of a separate machine filtering network traffic. Firewalls are common amongst machines that are permanently connected to the Internet.
What type of machines normall have a firewall?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Most bacterial species are either spherical, called cocci (sing. coccus, from Greek kokkos, grain, seed), or rod-shaped, called bacilli (sing. bacillus, from Latin baculus, stick). Elongation is associated with swimming. Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of species even have tetrahedral or cuboidal shapes. More recently, some bacteria were discovered deep under Earth's crust that grow as branching filamentous types with a star-shaped cross-section. The large surface area to volume ratio of this morphology may give these bacteria an advantage in nutrient-poor environments. This wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and is important because it can influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids and escape predators.
What type of bacteria usually takes rod-shaped form?
A: bacilli

Context and question: British post-punk entered the 1980s with support from members of the critical communityAmerican critic Greil Marcus characterised "Britain's postpunk pop avant-garde" in a 1980 Rolling Stone article as "sparked by a tension, humour and sense of paradox plainly unique in present day pop music"as well as media figures such as BBC DJ John Peel, while several groups, such as PiL and Joy Division, achieved some success in the popular charts. The network of supportive record labels that included Industrial, Fast, E.G., Mute, Axis/4AD and Glass continued to facilitate a large output of music, by artists such as the Raincoats, Essential Logic, Killing Joke, the Teardrop Explodes, and the Psychedelic Furs.
What nationality was the critic who positively characterized Britain's postpunk scene in an 1980 Rolling Stone article?
Answer: American

Question: The bank must also co-operate within the EU and internationally with third bodies and entities. Finally, it contributes to maintaining a stable financial system and monitoring the banking sector. The latter can be seen, for example, in the bank's intervention during the subprime mortgage crisis when it loaned billions of euros to banks to stabilise the financial system. In December 2007, the ECB decided in conjunction with the Federal Reserve System under a programme called Term auction facility to improve dollar liquidity in the eurozone and to stabilise the money market.
Is there an answer to this question: Besides cooperating with other financial institutions, how does the ECB help to maintain stability?

Answer: contributes to maintaining a stable financial system and monitoring the banking sector

QUES: The city proper is home to less than one-thirteenth of the population of South Florida. Miami is the 42nd-most populous city in the United States. The Miami metropolitan area, which includes Miami-Dade, Broward and Palm Beach counties, had a combined population of more than 5.5 million people, ranked seventh largest in the United States, and is the largest metropolitan area in the Southeastern United States. As of 2008[update], the United Nations estimates that the Miami Urban Agglomeration is the 44th-largest in the world.
