input question: Extract the answer to the question from the following context. Question: What was the system to replace AI? Context: Airborne Interception radar (AI) was unreliable. The heavy fighting in the Battle of Britain had eaten up most of Fighter Command's resources, so there was little investment in night fighting. Bombers were flown with airborne search lights out of desperation[citation needed], but to little avail. Of greater potential was the GL (Gunlaying) radar and searchlights with fighter direction from RAF fighter control rooms to begin a GCI system (Ground Control-led Interception) under Group-level control (No. 10 Group RAF, No. 11 Group RAF and No. 12 Group RAF).???
output answer: GCI system

input question: Extract the answer to the question from the following context. Question: who is the second leader mentioned? Context: The Russian army withdrew and retreated past Moscow. Napoleon entered the city, assuming its fall would end the war and Alexander would negotiate peace. However, on orders of the city's governor Feodor Rostopchin, rather than capitulation, Moscow was burned. After five weeks, Napoleon and his army left. In early November Napoleon got concerned about loss of control back in France after the Malet coup of 1812. His army walked through snow up to their knees and nearly 10,000 men and horses froze to death on the night of 8/9 November alone. After Battle of Berezina Napoleon succeeded to escape but had to abandon much of the remaining artillery and baggage train. On 5 December, shortly before arriving in Vilnius, Napoleon left the army in a sledge.???
output answer: Alexander

input question: Extract the answer to the question from the following context. Question: What territory did the Austrian army retreat to? Context: In the early morning of 10 April, leading elements of the Austrian army crossed the Inn River and invaded Bavaria. The early Austrian attack surprised the French; Napoleon himself was still in Paris when he heard about the invasion. He arrived at Donauwörth on the 17th to find the Grande Armée in a dangerous position, with its two wings separated by 75 miles (121 km) and joined together by a thin cordon of Bavarian troops. Charles pressed the left wing of the French army and hurled his men towards the III Corps of Marshal Davout. In response, Napoleon came up with a plan to cut off the Austrians in the celebrated Landshut Maneuver. He realigned the axis of his army and marched his soldiers towards the town of Eckmühl. The French scored a convincing win in the resulting Battle of Eckmühl, forcing Charles to withdraw his forces over the Danube and into Bohemia. On 13 May, Vienna fell for the second time in four years, although the war continued since most of the Austrian army had survived the initial engagements in Southern Germany.???
output answer:
Bohemia
