Problem: Arsenal F.C.:

For many years Arsenal's away colours were white shirts and either black or white shorts. In the 196970 season, Arsenal introduced an away kit of yellow shirts with blue shorts. This kit was worn in the 1971 FA Cup Final as Arsenal beat Liverpool to secure the double for the first time in their history. Arsenal reached the FA Cup final again the following year wearing the red and white home strip and were beaten by Leeds United. Arsenal then competed in three consecutive FA Cup finals between 1978 and 1980 wearing their "lucky" yellow and blue strip, which remained the club's away strip until the release of a green and navy away kit in 198283. The following season, Arsenal returned to the yellow and blue scheme, albeit with a darker shade of blue than before.

What is the difference in the Arsenal color of blue in the away kit after 1983?

A: darker shade

Problem: Royal Institute of British Architects:

Architectural design competitions are used by an organisation that plans to build a new building or refurbish an existing building. They can be used for buildings, engineering work, structures, landscape design projects or public realm artworks. A competition typically asks for architects and/or designers to submit a design proposal in response to a given Brief. The winning design will then be selected by an independent jury panel of design professionals and client representatives. The independence of the jury is vital to the fair conduct of a competition.

What is not provided to guide entrants in an architectural competition?

Problem: Web browser:

The most recent major entrant to the browser market is Chrome, first released in September 2008. Chrome's take-up has increased significantly year by year, by doubling its usage share from 8% to 16% by August 2011. This increase seems largely to be at the expense of Internet Explorer, whose share has tended to decrease from month to month. In December 2011, Chrome overtook Internet Explorer 8 as the most widely used web browser but still had lower usage than all versions of Internet Explorer combined. Chrome's user-base continued to grow and in May 2012, Chrome's usage passed the usage of all versions of Internet Explorer combined. By April 2014, Chrome's usage had hit 45%.

What was IE's increase in usage percentage in August 2011?
