Problem: Please answer a question about the following article about High-definition television:
Initially the existing 5:3 aspect ratio had been the main candidate but, due to the influence of widescreen cinema, the aspect ratio 16:9 (1.78) eventually emerged as being a reasonable compromise between 5:3 (1.67) and the common 1.85 widescreen cinema format. An aspect ratio of 16:9 was duly agreed upon at the first meeting of the IWP11/6 working party at the BBC's Research and Development establishment in Kingswood Warren. The resulting ITU-R Recommendation ITU-R BT.709-2 ("Rec. 709") includes the 16:9 aspect ratio, a specified colorimetry, and the scan modes 1080i (1,080 actively interlaced lines of resolution) and 1080p (1,080 progressively scanned lines). The British Freeview HD trials used MBAFF, which contains both progressive and interlaced content in the same encoding.
Which aspect ratio was the early favorite?
A: 5:3

Problem: Please answer a question about the following article about Arena Football League:
Following the suspension of the AFL's 2009 season, league officials and owners of af2 (which had played its season as scheduled) began discussing the future of arena football and the two leagues. With its 50.1 percent ownership of af2, the AFL's bankruptcy and dissolution prompted the dissolution of af2 as well. That league was formally considered disbanded on September 8, 2009, when no owner committed his or her team to the league's eleventh season by that deadline. For legal reasons, af2 league officials and owners agreed to form a new legal entity, Arena Football 1 (AF1), with former AFL teams the Arizona Rattlers and Orlando Predators joining the former af2.
On what date was af2 regarded as disbanded?
A: September 8, 2009
