Problem: San Diego's roadway system provides an extensive network of routes for travel by bicycle. The dry and mild climate of San Diego makes cycling a convenient and pleasant year-round option. At the same time, the city's hilly, canyon-like terrain and significantly long average trip distancesbrought about by strict low-density zoning lawssomewhat restrict cycling for utilitarian purposes. Older and denser neighborhoods around the downtown tend to be utility cycling oriented. This is partly because of the grid street patterns now absent in newer developments farther from the urban core, where suburban style arterial roads are much more common. As a result, a vast majority of cycling-related activities are recreational. Testament to San Diego's cycling efforts, in 2006, San Diego was rated as the best city for cycling for U.S. cities with a population over 1 million.
Why are older neighborhoods in San Diego popular with cyclists?

Answer: the grid street patterns

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Almost 60 years later, 80 year old career criminal Henry (Harry) James Burge claimed to have committed the theft, confessing to a newspaper, with the story being published in the Sunday Pictorial newspaper on 23 February 1958. He claimed to have carried out the robbery with two other men, although when discrepancies with a contemporaneous report in the Birmingham Post newspaper (the crime pre-dated written police reports) in his account of the means of entry and other items stolen, detectives decided there was no realistic possibility of a conviction and the case was closed. Burge claimed the cup had been melted down to make counterfeit half-crown coins, which matched known intelligence of the time, in which stolen silver was being used to forge coins which were then laundered through betting shops at a local racecourse, although Burge had no past history of forgery in a record of 42 previous convictions for which he had spent 42 years in prison. He had been further imprisoned in 1957 for seven years for theft from cars. Released in 1961, he died in 1964.
What did Burge do with the cup?
A: the cup had been melted down to make counterfeit half-crown coins

Question: Although initially thought to have originated as a manmade variant of an extant canid species (variously supposed as being the dhole, golden jackal, or gray wolf), extensive genetic studies undertaken during the 2010s indicate that dogs diverged from an extinct wolf-like canid in Eurasia 40,000 years ago. Being the oldest domesticated animal, their long association with people has allowed dogs to be uniquely attuned to human behavior, as well as thrive on a starch-rich diet which would be inadequate for other canid species.
Is there an answer to this question: What decade had significant studies of dog genes to determine origins?

Answer: 2010s

The consensus among linguists is that modern, standard Czech originated during the eighteenth century. By then the language had developed a literary tradition, and since then it has changed little; journals from that period have no substantial differences from modern standard Czech, and contemporary Czechs can understand them with little difficulty. Changes include the morphological shift of i to ej and e to i (although e survives for some uses) and the merging of i and the former eji. Sometime before the eighteenth century, the Czech language abandoned a distinction between phonemic /l/ and // which survives in Slovak.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When do linguists agree modern Czech originated?
Ah, so..
the eighteenth century
