In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

[EX Q]: Question: What was the former name of the Blohmn & Voss aircraft division? Passage:Soon after the start of World War II, it was proposed to convert the four prototypes to long-range maritime patrol aircraft. V2 underwent a trial modification. It was fitted with an extended nose section with extensive glazing (like the Heinkel He 111 H-6), defensive armament (a 7.92 mm/.312 in MG 15 machine gun in the nose, twin-beam positions, a ventral cupola, and a powered dorsal turret), a compartment for ordnance in the fuselage, and navigation and military radio equipment. The company had by now been renamed as the Blohm & Voss aircraft division so the converted aircraft was redesignated the BV 142 V2/U1 while the V1 was similarly converted. Both were used operationally from late 1940 and were posted to the Luftwaffes second surveillance Group. This unit was assigned to the operations staff of Luftflotte III in France. However, their performance was disappointing, and after only a few missions they were withdrawn from service in 1942. Aircraft V3 and V4 were used as transport aircraft for the occupation of Denmark and in the Norway campaign with the KGr.z.b.V. 105 (Special combat team) and could transport 30 fully equipped soldiers over 4,000 km (2,490 mi). The ultimate fate of V3 and V4 is unknown. It was later planned to use the V1 and V2 to carry the Henschel GT 1200C guided torpedo, but the plan was cancelled.

[EX Q]: Question: Which of the two rivers the Panzer Corps crossed was larger? Passage:In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery. The main effort, or schwerpunkt, would consist of XLVII Panzer Corps and LVIII Panzer Corps advancing west across the River Our at Ouren from the south or left flank of the German army front. They would then occupy the transportation center of Bastogne, before crossing the Meuse River at Namur. The third group, LXVI Corps, would advance west on either side of the Schnee Eifel. This northernmost, or right wing, element would flank and begin an envelopment of the American forces occupying fortifications on the Schnee Eifel and then converge on the town of Winterspelt. From there, LXVI Corps would cross the Our river and occupy St. Vith on the first day of the attack. LXVI Corps was the weakest of the three corps, with no attached tank division or motor transport, but did include an attached assault gun battalion. The Panzer Lehr Division (Armor Demonstration Division) and the Führer Begleit Brigade (Führer Escort Brigade) were to be held in reserve, with the Führer Begleit only usable with Model's express permission. Manteuffel's preference for the "little slam", or limited solution, was reflected in the absence of planning beyond reaching the Meuse River.
