Example Input: Passage: The policy change faced legal challenges. Following a challenge in the U.S. District Court for the District of Columbia, on October 30, 2017, Judge Colleen Kollar-Kotelly blocked enforcement of the ban, writing that as far as could be seen, "all of the reasons proffered by the president for excluding transgender individuals from the military in this case were not merely unsupported, but were actually contradicted by the studies, conclusions and judgment of the military itself". In March 2018, Trump announced a new policy on transgender service members, namely a ban on those with a diagnosis of gender dysphoria, which would effectively be a ban on most transgender service members. The new policy was challenged in the U.S. District Court for the Western District of Washington. On April 13, 2018 Judge Marsha J. Pechman blocked enforcement of the policy, ruling that the administration's updated policy essentially repeated the same issues as its predecessor order from 2017, and that transgender service members (and transgender individuals as a class) were a protected class entitled to strict scrutiny of adverse laws (or at worst, a quasi-suspect class), and ordered that matter continue to a full trial hearing on the legality of the proposed policy. On January 21, 2019, the Supreme Court with Chief Justice John Roberts and Justices Samuel Alito, Neil Gorsuch, Brett Kavanaugh and Clarence Thomas forming the majority for the 5-4 opinion allowed Trump's policy to go into effect while challenges in lower courts are adjudicated. On March 12, 2019, acting Deputy Defense Secretary David Norquist signed a directive to allow Trump's policy to take effect in 30 days.

Example Input: Passage: The Prodigal Son is a best-selling novel by Hall Caine, published in November 1904 by Heinemann and translated into thirteen languages. It is set in a sheep-rearing community in rural Iceland, with scenes in London and the French Riviera. At the same time Caine adapted the novel into a play. The copyright performance was held at the Grand Theatre, Douglas, Isle of Man. American and British productions opened days apart in 1905, at the National Theatre in Washington, D. C. on 28 August, the New Amsterdam Theatre in New York City on 4 September and at the Theatre Royal, Drury Lane, London on 7 September, with George Alexander playing Oscar and Caine's sister Lilian playing Thora.

She marries Oscar after Magnus releases her from the engagement. When Thora dies, a distraught Oscar places the only copies of his compositions in her coffin. Later he has her grave opened and his music retrieved. It was filmed in 1923. A.E. Coleby's 18,454 feet, nineteen reel film The Prodigal Son became the longest commercially made British film.
