Input: Arena Football League
On January 6, 2016, the league took over "ownership and operational control" of the Portland Thunder from its previous owners. The AFL stated this move was made after months of trying work out an arrangement "to provide financial and operational support." On February 3, 2016, it was announced that the franchise will start from scratch and no longer be called the "Thunder" as the name and trademarks belong to former franchise owner Terry Emmert (similar to the Jerry Jones move with the Desperados). AFL commissioner Scott Butera announced that a new identity will be announced at a later date.

Who owned the trademark to the Portland Thunder?
Output: Terry Emmert

Input: Solar energy
In addition, land availability has a large effect on the available solar energy because solar panels can only be set up on land that is unowned and suitable for solar panels. Roofs have been found to be a suitable place for solar cells, as many people have discovered that they can collect energy directly from their homes this way. Other areas that are suitable for solar cells are lands that are unowned by businesses where solar plants can be established.

Why are roofs a good place for solar panels?
Output: many people have discovered that they can collect energy directly from their homes this way

Input: Queen Victoria
In March 1861, Victoria's mother died, with Victoria at her side. Through reading her mother's papers, Victoria discovered that her mother had loved her deeply; she was heart-broken, and blamed Conroy and Lehzen for "wickedly" estranging her from her mother. To relieve his wife during her intense and deep grief, Albert took on most of her duties, despite being ill himself with chronic stomach trouble. In August, Victoria and Albert visited their son, the Prince of Wales, who was attending army manoeuvres near Dublin, and spent a few days holidaying in Killarney. In November, Albert was made aware of gossip that his son had slept with an actress in Ireland. Appalled, Albert travelled to Cambridge, where his son was studying, to confront him. By the beginning of December, Albert was very unwell. He was diagnosed with typhoid fever by William Jenner, and died on 14 December 1861. Victoria was devastated. She blamed her husband's death on worry over the Prince of Wales's philandering. He had been "killed by that dreadful business", she said. She entered a state of mourning and wore black for the remainder of her life. She avoided public appearances, and rarely set foot in London in the following years. Her seclusion earned her the nickname "widow of Windsor".

What caused Prince Albert's death?
Output: typhoid fever
