Input: Article: The Tibetan Empire emerged in the 7th century, but with the fall of the empire the region soon divided into a variety of territories. The bulk of western and central Tibet (U-Tsang) was often at least nominally unified under a series of Tibetan governments in Lhasa, Shigatse, or nearby locations; these governments were at various times under Mongol and Chinese overlordship. The eastern regions of Kham and Amdo often maintained a more decentralized indigenous political structure, being divided among a number of small principalities and tribal groups, while also often falling more directly under Chinese rule after the Battle of Chamdo; most of this area was eventually incorporated into the Chinese provinces of Sichuan and Qinghai. The current borders of Tibet were generally established in the 18th century.

Now answer this question: When were the current borders of Tibet established?

Output: 18th century

Input: Article: The name of the winning team is engraved on the silver band around the base as soon as the final has finished, in order to be ready in time for the presentation ceremony. This means the engraver has just five minutes to perform a task which would take twenty under normal conditions, although time is saved by engraving the year on during the match, and sketching the presumed winner. During the final, the trophy wears is decorated with ribbons in the colours of both finalists, with the loser's ribbons being removed at the end of the game. Traditionally, at Wembley finals, the presentation is made at the Royal Box, with players, led by the captain, mounting a staircase to a gangway in front of the box and returning by a second staircase on the other side of the box. At Cardiff the presentation was made on a podium on the pitch.

Now answer this question: Is the trophy decorated?

Output: the trophy wears is decorated with ribbons in the colours of both finalists, with the loser's ribbons being removed at the end of the game.

Input: Article: The expression of genes encoded in DNA begins by transcribing the gene into RNA, a second type of nucleic acid that is very similar to DNA, but whose monomers contain the sugar ribose rather than deoxyribose. RNA also contains the base uracil in place of thymine. RNA molecules are less stable than DNA and are typically single-stranded. Genes that encode proteins are composed of a series of three-nucleotide sequences called codons, which serve as the "words" in the genetic "language". The genetic code specifies the correspondence during protein translation between codons and amino acids. The genetic code is nearly the same for all known organisms.:4.1

Now answer this question: What specifies the correspondence between codons and amino acids during protein translation?

Output:
The genetic code
