Input: Consider Input: Question: Where was the division based that was able to dig in for a defense of Bastogne? Passage:The 9th Armored Division landed in Normandy late in September 1944, and first went into the line, 23 October 1944, on patrol duty in a quiet sector along the Luxembourg-German frontier. When the Germans launched their winter offensive on 16 December 1944, the 9th, with no real combat experience, suddenly found itself engaged in heavy fighting. The Division saw its severest action at St. Vith, Echternach, and Bastogne, its units fighting in widely separated areas. Its stand at Bastogne held off the Germans long enough to enable the 101st Airborne Division to dig in for a defense of the city. After a rest period in January 1945, the Division prepared to drive across the Roer River. The offensive was launched on 28 February 1945 and the 9th crossed the Roer to Rheinbach, sending patrols into Remagen. On 7 March 1945, elements of the 9th Armored found that the Ludendorff Bridge was still standing. When German demolition charges failed to bring the bridge down, they crossed it, disarming and removing the remaining charges, which could have exploded at any time. The Division exploited the bridgehead, moving south and east across the Lahn River toward Limburg, where thousands of Allied prisoners were liberated from Stalag XIIA. The Division drove on to Frankfurt and then turned to assist in the closing of the Ruhr Pocket. In April it continued east, encircling Leipzig and securing a line along the Mulde River. The Division was shifting south to Czechoslovakia when the war in Europe ended on 9 May 1945. All units of CCB/9 AIB of the 9th Armored Division were awarded the Presidential Unit Citation for their actions in taking and defending the Ludendorff Bridge during the Battle of Remagen in World War II.

Input: Consider Input: Question: How old was the person who replaced Himmatsinhji in 1954 when Himmatsinhji died? Passage:After a brief period in the diplomatic service, Himmatsinhji returned to the army, seeing service in the Second World War. A war-substantive lieutenant-colonel at the war's end, he eventually reached the rank of major-general. He was appointed a Companion of the Order of the Indian Empire (CIE) in the 1946 New Year Honours. He was elected to the Central Legislative Assembly, India's pre-independence lower house, in 1946, and was later a member of the Constituent Assembly, the transitional body established after independence. A member of the Indian National Congress, he was a party whip before being appointed Deputy Minister of Defence in Jawaharlal Nehru's first ministry. In this position he chaired a committee responsible for recommended improvements to India's defences along its border with what was then the Kingdom of Tibet, prior to China's invasion and eventually annexation. Upon retirement, Himmatsinhji was appointed the first lieutenant-governor of Himachal Pradesh, a newly created Part C state of India. He served in the position from 1952 to 1954, when he was succeeded by Bajrang Bahadur Singh. Himmatsinhji died in January 1973.

Input: Consider Input: Question: Of the last two Ruthenian kings were joint rulers, which was the oldest? Passage:The Romanoviches (Izyaslavichi of Volhynia)were the line of Roman the Great, descended from Mstislav I of Kiev through his son Iziaslav II of Kiev and his grandson Mstislav II of Kiev, father of Roman the Great. The older Monomakhovychi line that ruled Principality of Volhynia, they were eventually crowned kings of Galicia and Volhynia and ruled until 1323. Romanovychi displaced the older line of Izyaslavychi from Turov and Volhynia as well as Rostyslavychi from Galicia. The last were two brothers of Romanovychi, Andrew and Lev II, who ruled jointly and were slain trying to repel Mongol incursions. The Polish king, Władysław I the Elbow-high, in his letter to the Pope wrote with regret: "The two last Ruthenian kings, that had been firm shields for Poland from the Tatars, left this world and after their death Poland is directly under Tatar threat." Losing their leadership role, Rurikids, however, continued to play a vital role in the Grand Duchy of Lithuania and the later Polish-Lithuanian Commonwealth. Most notably, the Ostrogski family held the title of Grand Hetman of Lithuania and strove to preserve the Ruthenian language and Eastern Orthodoxy in this part of Europe. It is thought that the Drutsk and related princely families may also descend from Roman the Great.
