Input: Read this: In many countries, national and regional poultry shows are held where enthusiasts exhibit their birds which are judged on certain phenotypical breed traits as specified by their respective breed standards. The idea of poultry exhibition may have originated after cockfighting was made illegal, as a way of maintaining a competitive element in poultry husbandry. Breed standards were drawn up for egg-laying, meat-type, and purely ornamental birds, aiming for uniformity. Sometimes, poultry shows are part of general livestock shows, and sometimes they are separate events such as the annual "National Championship Show" in the United Kingdom organised by the Poultry Club of Great Britain.
Question: What was never made illegal that involves birds fighting?

Output: unanswerable


Input: Read this: Saint Helena has the international calling code +290 which, since 2006, Tristan da Cunha shares. Saint Helena telephone numbers changed from 4 to 5 digits on 1 October 2013 by being prefixed with the digit "2", i.e. 2xxxx, with the range 5xxxx being reserved for mobile numbering, and 8xxx being used for Tristan da Cunha numbers (these still shown as 4 digits).
Question: What is the international calling code for Saint Helena?

Output: +290


Input: Read this: The first record of the existence of a settlement at Plymouth was in the Domesday Book in 1086 as Sudtone, Saxon for south farm, located at the present day Barbican. From Saxon times, it was in the hundred of Roborough. In 1254 it gained status as a town and in 1439, became the first town in England to be granted a Charter by Parliament. Between 1439 and 1934, Plymouth had a Mayor. In 1914 the county boroughs of Plymouth and Devonport, and the urban district of East Stonehouse merged to form a single county borough of Plymouth. Collectively they were referred to as "The Three Towns".
Question: In what year was the Domesday Book compiled?

Output: 1086


Input: Read this: Translation is the process by which a mature mRNA molecule is used as a template for synthesizing a new protein.:6.2 Translation is carried out by ribosomes, large complexes of RNA and protein responsible for carrying out the chemical reactions to add new amino acids to a growing polypeptide chain by the formation of peptide bonds. The genetic code is read three nucleotides at a time, in units called codons, via interactions with specialized RNA molecules called transfer RNA (tRNA). Each tRNA has three unpaired bases known as the anticodon that are complementary to the codon it reads on the mRNA. The tRNA is also covalently attached to the amino acid specified by the complementary codon. When the tRNA binds to its complementary codon in an mRNA strand, the ribosome attaches its amino acid cargo to the new polypeptide chain, which is synthesized from amino terminus to carboxyl terminus. During and after synthesis, most new proteins must folds to their active three-dimensional structure before they can carry out their cellular functions.:3
Question: How many unpaired bases does each tRNA have?

Output:
three
