Example Input: Question: Was the people's Liberation Army still in operation during the civil war in 1949? Passage:In ancient times the area around Changzhi (Including Jincheng) was known as Shangdang. Changzhi was the site of the Shangdang Campaign, the first battle between the Kuomintang and the People's Liberation Army after the end of World War II. The campaign began in August 1945 and lasted until October. It began when the local Shanxi warlord, Yan Xishan, attempted to retake the region from Communist forces. Yan's forces were eventually defeated by an army led by Liu Bocheng, who was later named one of China's Ten Great Marshals. Liu's political commissar was Deng Xiaoping, who later became China's "paramount leader". The campaign ended with the complete destruction of Yan's army, most of which joined the Communists after surrendering. Following the Shangdang Campaign, the Communists remained in control of the region until they won the civil war in 1949.

Example Input: Question: How had long had it been since ground was broken at Yucca Mountain nuclear waste repository when Garland dissented in In re Aiken County? Passage:Garland has tended to favor deference to regulatory agencies. For example, in In re Aiken County (2013), Garland dissented when the court issued mandamus ordering the Nuclear Regulatory Commission to process the Yucca Mountain nuclear waste repository license. In Americans for Safe Access v. Drug Enforcement Administration (2013), Garland joined a divided court upholding the DEA's classification of marijuana as a Schedule I drug. However, according to Goldstein, in a number of split decisions on environmental law Garland "favored contested EPA regulations and actions when challenged by industry, and in other cases he has accepted challenges brought by environmental groups." In Rancho Viejo, LLC v. Norton (2003), Garland found the arroyo toad was protected by the federal Endangered Species Act. Then-Circuit Judge John Roberts dissented from the denial of rehearing en banc, writing that Congress's interstate commerce power cannot reach "a hapless toad that, for reasons of its own, lives its entire life in California."

Example Input: Question: What is the age difference between the actress who voiced Fiona and the actress originally cast to voice the role, but was fired? Passage:Created by screenwriters Ted Elliott and Terry Rossio, Fiona is loosely based on the unsightly princess in William Steig's children's book Shrek!, from which her role and appearance were significantly modified. The screenwriters adapted the character into a princess under a shapeshifting enchantment, an idea that was initially greatly contested by other filmmakers. Fiona is voiced by actress Cameron Diaz. Comedian and actress Janeane Garofalo was originally cast as the character until she was fired from the first film with little explanation, although it is believed that the producers found Garofalo's sarcastic approach to the princess unsuitable after Shrek's original voice actor died. Fiona was one of the first human characters to have a lead role in a computer-animated film, thus the animators aspired to make her both beautiful and realistic in appearance. However, an early test screening resulted in children reacting negatively towards the character's uncanny realism, prompting the animators to re-design Fiona into a more stylized, cartoonish heroine.
