In the United States it is likely that the gasoline one puts in ones motor vehicle contains ethanol made from corn.

So another quick one for fans of Sherlock Holmes. Holmes and Watson resided, according to the stories by Sir Arthur Conan Doyle, in a flat at 221B Baker Street in London. This address did not really exist at the time the Holmes stories were written (Baker Street addresses at the time only extended into the 100s), but later Baker Street was extended so that an address of 221 Baker Street became theoretically possible. Today if one were to mail a letter to that address it would be delivered to the Sherlock Holmes Museum. However if standard street numbering were used for the address of that museum what would the street number be?
