Problem: Madonna released the song "Hey You" for the Live Earth series of concerts. The song was available as a free download during its first week of release. She also performed it at the London Live Earth concert. Madonna announced her departure from Warner Bros. Records, and a new $120 million, ten-year 360 deal with Live Nation. She produced and wrote I Am Because We Are, a documentary on the problems faced by Malawians. The documentary was directed by Nathan Rissman, who worked as Madonna's gardener. She also directed her first film Filth and Wisdom. The plot of the film revolved around three friends and their aspirations. The Times said she had "done herself proud" while The Daily Telegraph described the film as "not an entirely unpromising first effort [but] Madonna would do well to hang on to her day job." In December 2007, the Rock and Roll Hall of Fame announced Madonna as one of the five inductees of 2008. At the induction ceremony on March 10, 2008, Madonna did not sing but asked fellow Hall of Fame inductees and Michigan natives The Stooges to perform her songs "Burning Up" and "Ray of Light". She thanked Christopher Flynn, her dance teacher from 35 years earlier, for his encouragement to follow her dreams.
What is the name of the first film Madonna directed?
The answer is the following: Filth and Wisdom

Problem: 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 issue can complicate electric railway service?
The answer is the following: different supply voltages and frequencies,

Problem: Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment. For example, even a seemingly innocuous device such as a disposable-camera flash unit, powered by a 1.5 volt AA battery, has a capacitor which may contain over 15 joules of energy and be charged to over 300 volts. This is easily capable of delivering a shock. Service procedures for electronic devices usually include instructions to discharge large or high-voltage capacitors, for instance using a Brinkley stick. Capacitors may also have built-in discharge resistors to dissipate stored energy to a safe level within a few seconds after power is removed. High-voltage capacitors are stored with the terminals shorted, as protection from potentially dangerous voltages due to dielectric absorption or from transient voltages the capacitor may pick up from static charges or passing weather events.
What device can be used to discharge large voltage capacitors?
The answer is the following: a Brinkley stick

Problem: In the 1990s and the new millennium, the city has produced a number of influential hip hop artists, including Eminem, the hip-hop artist with the highest cumulative sales, hip-hop producer J Dilla, rapper and producer Esham and hip hop duo Insane Clown Posse. The city is also home to rappers Big Sean and Danny Brown. The band Sponge toured and produced music, with artists such as Kid Rock and Uncle Kracker. The city also has an active garage rock genre that has generated national attention with acts such as: The White Stripes, The Von Bondies, The Detroit Cobras, The Dirtbombs, Electric Six, and The Hard Lessons.
Which band toured with Kid Rock?
The answer is the following:
Sponge
