[Q]: What numeral standard was used in the Super Bowl 4 logo?, Context: On June 4, 2014, the NFL announced that the practice of branding Super Bowl games with Roman numerals, a practice established at Super Bowl V, would be temporarily suspended, and that the game would be named using Arabic numerals as Super Bowl 50 as opposed to Super Bowl L. The use of Roman numerals will be reinstated for Super Bowl LI. Jaime Weston, the league's vice president of brand and creative, explained that a primary reason for the change was the difficulty of designing an aesthetically pleasing logo with the letter "L" using the standardized logo template introduced at Super Bowl XLV. The logo also deviates from the template by featuring large numerals, colored in gold, behind the Vince Lombardi Trophy, instead of underneath and in silver as in the standard logo.
[A]: Arabic

[Q]: What is the last place listed that engaged in the slave trade?, Context: The slave trade was engaged in by European state and non-state actors such as Great Britain, the Netherlands, Portugal and private companies, as well as various African states and non-state actors. With rising anti-slavery sentiment at home and changing economic realities, Great Britain outlawed the international slave trade in 1807. Following the Napoleonic Wars, Great Britain established the West Africa Squadron in an attempt to halt the international traffic in slaves. It stopped ships of other nations that were leaving the African coast with slaves; the seized slaves were taken to Freetown, a colony in West Africa originally established for the resettlement of freed slaves from Britain. Britain intervened in the Lagos Kingship power struggle by bombarding Lagos in 1851, deposing the slave trade friendly Oba Kosoko, helping to install the amenable Oba Akitoye, and signing the Treaty between Great Britain and Lagos on 1 January 1852. Britain annexed Lagos as a Crown Colony in August 1861 with the Lagos Treaty of Cession. British missionaries expanded their operations and travelled further inland. In 1864, Samuel Ajayi Crowther became the first African bishop of the Anglican Church.
[A]: various African states

[Q]: At the turn of the second century what was it about Estonia workers that helped to give them an advantage over other place in Eastern Europe?, Context: Estonia has had a market economy since the end of the 1990s and one of the highest per capita income levels in Eastern Europe. Proximity to the Scandinavian markets, its location between the East and West, competitive cost structure and a highly skilled labour force have been the major Estonian comparative advantages in the beginning of the 2000s (decade).

The current government has pursued tight fiscal policies, resulting in balanced budgets and low public debt.
