Input: Article: Defining exactly what section of a DNA sequence comprises a gene is difficult. Regulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons. Regulatory regions can even be on entirely different chromosomes and operate in trans to allow regulatory regions on one chromosome to come in contact with target genes on another chromosome.

Now answer this question: What is an example of a regulatory region of a gene that does not have to close to the coding sequence?

Output: enhancers

Input: Article: As of the 201516 season, Premier League football has been played in 53 stadiums since the formation of the Premier League in 1992. The Hillsborough disaster in 1989 and the subsequent Taylor Report saw a recommendation that standing terraces should be abolished; as a result all stadiums in the Premier League are all-seater. Since the formation of the Premier League, football grounds in England have seen constant improvements to capacity and facilities, with some clubs moving to new-build stadiums. Nine stadiums that have seen Premier League football have now been demolished. The stadiums for the 201011 season show a large disparity in capacity: Old Trafford, the home of Manchester United has a capacity of 75,957 with Bloomfield Road, the home of Blackpool, having a capacity of 16,220. The combined total capacity of the Premier League in the 201011 season is 770,477 with an average capacity of 38,523.

Now answer this question: In how many stadiums had Premier League been played as of the 2015-16 season?

Output: 53

Input: Article: The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militiasfrequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.

Now answer this question: When did the British Army and Royal Navy withdraw from Halifax?

Output:
1906
