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.

Ex Output:
Arabic

What was improved due to the better recording technology?, Context: Whether there are measurable changes in the sea level relative to the islands of Tuvalu is a contentious issue. There were problems associated with the pre-1993 sea level records from Funafuti which resulted in improvements in the recording technology to provide more reliable data for analysis. The degree of uncertainty as to estimates of sea level change relative to the islands of Tuvalu was reflected in the conclusions made in 2002 from the available data. The 2011 report of the Pacific Climate Change Science Program published by the Australian Government, concludes: "The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm (0.2 in) per year."
