Input: Read this: London's bus network is one of the largest in the world, running 24 hours a day, with about 8,500 buses, more than 700 bus routes and around 19,500 bus stops.

The distinctive red double-decker buses are an internationally recognised trademark of London transport along with black cabs and the Tube.
Question: How much revenue is generated yearly by London's public bus service?

Output: £850 million


QUES: Some polychaetes breed only once in their lives, while others breed almost continuously or through several breeding seasons. While most polychaetes remain of one sex all their lives, a significant percentage of species are full hermaphrodites or change sex during their lives. Most polychaetes whose reproduction has been studied lack permanent gonads, and it is uncertain how they produce ova and sperm. In a few species the rear of the body splits off and becomes a separate individual that lives just long enough to swim to a suitable environment, usually near the surface, and spawn.

How many polychaetes breed an infinite amount of times?
What is the answer?
ANS: unanswerable


QUES: Yale has a complicated relationship with its home city; for example, thousands of students volunteer every year in a myriad of community organizations, but city officials, who decry Yale's exemption from local property taxes, have long pressed the university to do more to help. Under President Levin, Yale has financially supported many of New Haven's efforts to reinvigorate the city. Evidence suggests that the town and gown relationships are mutually beneficial. Still, the economic power of the university increased dramatically with its financial success amid a decline in the local economy.
What hasn't been the effect of Yale and New Haven's relationship on Yale?

ANS: unanswerable


Commensal relationships may involve one organism using another for transportation (phoresy) or for housing (inquilinism), or it may also involve one organism using something another created, after its death (metabiosis). Examples of metabiosis are hermit crabs using gastropod shells to protect their bodies and spiders building their webs on plants.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the term for a relationship where one organism provides a dwelling for the other?
Ah, so.. inquilinism


Question: Interstate 26 begins in downtown Charleston, with exits to the Septima Clark Expressway, the Arthur Ravenel, Jr. Bridge and Meeting Street. Heading northwest, it connects the city to North Charleston, the Charleston International Airport, Interstate 95, and Columbia. The Arthur Ravenel, Jr. Bridge and Septima Clark Expressway are part of U.S. Highway 17, which travels east-west through the cities of Charleston and Mount Pleasant. The Mark Clark Expressway, or Interstate 526, is the bypass around the city and begins and ends at U.S. Highway 17. U.S. Highway 52 is Meeting Street and its spur is East Bay Street, which becomes Morrison Drive after leaving the east side. This highway merges with King Street in the city's Neck area (industrial district). U.S. Highway 78 is King Street in the downtown area, eventually merging with Meeting Street.
Try to answer this question if possible: What area in Charleston isn't considered the 'industrial area'?
Answer: unanswerable


Problem: The impressive, costly, and centralised rites to the deities of the Roman state were vastly outnumbered in everyday life by commonplace religious observances pertaining to an individual's domestic and personal deities, the patron divinities of Rome's various neighborhoods and communities, and the often idiosyncratic blends of official, unofficial, local and personal cults that characterised lawful Roman religion. In this spirit, a provincial Roman citizen who made the long journey from Bordeaux to Italy to consult the Sibyl at Tibur did not neglect his devotion to his own goddess from home:
