Example Input: Passage: Vance Astro first appeared as a founding member of the Guardians of the Galaxy. According to Roy Thomas, all of the Guardians of the Galaxy were created in a conference between Arnold Drake and Stan Lee, but it remains uncertain whether each individual character was created by Drake, Lee, or both. The Guardians of the Galaxy debuted in the partial reprint title Marvel Super-Heroes with issue #18 (Jan. 1969), written by Drake and penciled by Gene Colan. After five years' absence, he was revived in several Marvel titles: Marvel Two-In-One #4-5 (July-Sept. 1974), Giant Size Defenders #5, and Defenders #26-29 (July-Nov. 1975). In each case, other heroes such as Captain America, the Thing, and the Defenders aid Astro and the Guardians against the alien Badoon. The first story established that if Vance Astro's containment suit were breached, he would age 1,000 years in a second. This drew numerous queries from readers, and the letters page in Marvel Two-in-One #7 responded by stating that Vance feeds and defecates intravenously. The Guardians were also featured in Marvel Presents #3-12 (Feb. 1976 - Aug. 1977).

Example Input: Passage: The Battle of Pakchon (5 November 1950), also known as the Battle of Bochuan (), took place ten days after the start of the Chinese First Phase Offensive, following the entry of the Chinese People's Volunteer Army (PVA) into the Korean War. The offensive reversed the United Nations Command (UN) advance towards the Yalu River which had occurred after their intervention in the wake of the North Korean invasion of South Korea at the start of the war. The battle was fought between British and Australian forces from the 27th British Commonwealth Brigade with American armour and artillery in support, and the PVA 117th Division of the 39th Army, around the village of Pakchon on the Taeryong River. After capturing Chongju on 30 October the British and Australians had been ordered to pull back to Pakchon in an attempt to consolidate the western flank of the US Eighth Army. Meanwhile, immediately following their success at Unsan against the Americans, the PVA 117th Division had attacked southward, intending to cut off the UN forces as they withdrew in the face of the unexpected PVA assault. To halt the PVA advance, the 27th British Commonwealth Brigade was ordered to defend the lower crossings of the Taeryong and Chongchon rivers as part of a rearguard, in conjunction with the US 24th Infantry Division further upstream on the right.
