Extract the answer to the question from the following context. Question: What is meat a source of? Context: Additionally, genes can have regulatory regions many kilobases upstream or downstream of the open reading frame. These act by binding to transcription factors which then cause the DNA to loop so that the regulatory sequence (and bound transcription factor) become close to the RNA polymerase binding site. For example, enhancers increase transcription by binding an activator protein which then helps to recruit the RNA polymerase to the promoter; conversely silencers bind repressor proteins and make the DNA less available for RNA polymerase.
Ans: protein

Extract the answer to the question from the following context. Question: Who had been employed by the Mirror? Context: Murdoch found he had such a rapport with Larry Lamb over lunch that other potential recruits as editor were not interviewed and Lamb was appointed as the first editor of the new Sun. He was scathing in his opinion of the Mirror, where he had recently been employed as a senior sub-editor, and shared Murdoch's view that a paper's quality was best measured by its sales, and he regarded the Mirror as overstaffed, and primarily aimed at an ageing readership. Lamb hastily recruited a staff of about 125 reporters, who were mostly selected for their availability rather than their ability.
Ans: Lamb

Extract the answer to the question from the following context. Question: How many losses do the Cubs have? Context: On April 23, 2008, against the Colorado Rockies, the Cubs recorded the 10,000th regular-season win in their franchise's history dating back to the beginning of the National League in 1876. The Cubs reached the milestone with an overall National League record of 10,000-9,465. Chicago was only the second club in Major League Baseball history to attain this milestone, the first having been the San Francisco Giants in mid-season 2005. The Cubs, however, hold the mark for victories for a team in a single city. The Chicago club's 77–77 record in the National Association (1871, 1874–1875) is not included in MLB record keeping. Post-season series are also not included in the totals. To honor the milestone, the Cubs flew an extra white flag displaying "10,000" in blue, along with the customary "W" flag.
Ans: 9,465
