Problem: Pope Paul VI:

During Vatican II, the Council Fathers avoided statements which might anger Christians of other faiths.[page needed] Cardinal Augustin Bea, the President of the Christian Unity Secretariat, always had the full support of Paul VI in his attempts to ensure that the Council language was friendly and open to the sensitivities of Protestant and Orthodox Churches, whom he had invited to all sessions at the request of Pope John XXIII. Bea also was strongly involved in the passage of Nostra aetate, which regulates the Church's relations with the Jewish faith and members of other religions.[d]

Which cardinal became heavily engaged in the passage of Nostra aetate?
---
A: Cardinal Augustin Bea

Problem: Improved aircraft designs were in the offing with the Bristol Beaufighter, then under development. It would prove formidable, but its development was slow. The Beaufighter had a maximum speed of 320 mph (510 km/h), an operational ceiling of 26,000 ft (7,900 m) and a climb rate of 2,500 ft (760 m) per minute. Its armament of four 20 mm (0.79 in) Hispano cannon and six .303 in Browning machine guns offered a serious threat to German bombers. On 19 November, John Cunningham of No. 604 Squadron RAF shot down a bomber flying an AI-equipped Beaufighter. It was the first air victory for the airborne radar.
What day was the first victory the RAF had with airborne radar?

Answer: 19 November

Who must approve presidential appointees to the Supreme Court?

Question: In the early hours of 7 December (Hawaiian time), Japan launched a major surprise carrier-based air strike on Pearl Harbor without explicit warning, which crippled the U.S. Pacific Fleet, leaving eight American battleships out of action, 188 American aircraft destroyed, and 2,403 American citizens dead. At the time of the attack, the U.S. was not officially at war anywhere in the world, which means that the people killed or property destroyed at Pearl Harbor by the Japanese attack had a non-combatant status.[nb 11] The Japanese had gambled that the United States, when faced with such a sudden and massive blow, would agree to a negotiated settlement and allow Japan free rein in Asia. This gamble did not pay off. American losses were less serious than initially thought: The American aircraft carriers, which would prove to be more important than battleships, were at sea, and vital naval infrastructure (fuel oil tanks, shipyard facilities, and a power station), submarine base, and signals intelligence units were unscathed. Japan's fallback strategy, relying on a war of attrition to make the U.S. come to terms, was beyond the IJN's capabilities.
Is there an answer to this question: How many US citizens were killed in the attack on Pearl Harbor by Japan?

Answer: 2,403
