The problem: Answer a question about this article:
The Football League was founded in 1888, 16 years after the first FA Cup competition. Since the creation of The Football League, Tottenham Hotspur is the only non-league "giant-killer" to win the Cup, taking the 1901 FA Cup with a victory over reigning league runners-up Sheffield United: although at that time, there were only two divisions and 36 clubs in the Football League, and Spurs were champions of the next lowest football tier - the Southern League and probably already good enough for the First Division (as was shown when they joined the Second Division in 1908 and immediately won promotion to the First.) Only two other actual non-League clubs have even reached the final since the founding of the League: Sheffield Wednesday in 1890 (champions of the Football Alliance, a rival league which was already effectively the Second Division, which it formally became in 1892 Wednesday being let straight into the First Division), and Southampton in 1900 and 1902 (in which years they were also Southern League champions, proving the strength of that league: again, they were probably of equivalent standard to a First Division club at the time, but Southampton's form subsequently faded and they did not join the League till 1920 and the formation of the Third Division.)
How many clubs where in the football league?
****
The answer: 36 clubs in the Football League

Problem: Please answer a question about the following article about Queen (band):
After working on various solo projects during 1988 (including Mercury's collaboration with Montserrat Caballe, Barcelona), the band released The Miracle in 1989. The album continued the direction of A Kind of Magic, using a pop-rock sound mixed with a few heavy numbers. It spawned the European hits "I Want It All", "Breakthru", "The Invisible Man", "Scandal", and "The Miracle". The Miracle also began a change in direction of Queen's songwriting philosophy. Since the band's beginning, nearly all songs had been written by and credited to a single member, with other members adding minimally. With The Miracle, the band's songwriting became more collaborative, and they vowed to credit the final product only to Queen as a group.
Who did Freddie Mercury collaborate with in 1988?

Here is a question about this article: Disadvantages of electric traction include high capital costs that may be uneconomic on lightly trafficked routes; a relative lack of flexibility since electric trains need electrified tracks or onboard supercapacitors and charging infrastructure at stations; and a vulnerability to power interruptions. Different regions may use different supply voltages and frequencies, complicating through service. The limited clearances available under catenaries may preclude efficient double-stack container service. The lethal voltages on contact wires and third rails are a safety hazard to track workers, passengers and trespassers. Overhead wires are safer than third rails, but they are often considered unsightly.
What is the answer to this question: What is a safety hazard to track workers?
