Passage: The first landing was followed by another, precision landing on Apollo 12 in November 1969. NASA had achieved its first landing goal with enough Apollo spacecraft and Saturn V launchers left for eight follow-on lunar landings through Apollo 20, conducting extended-endurance missions and transporting the landing crews in Lunar Roving Vehicles on the last five. They also planned an Apollo Applications Program to develop a longer-duration Earth orbital workshop (later named Skylab) to be constructed in orbit from a spent S-IVB upper stage, using several launches of the smaller Saturn IB launch vehicle. But planners soon decided this could be done more efficiently by using the two live stages of a Saturn V to launch the workshop pre-fabricated from an S-IVB (which was also the Saturn V third stage), which immediately removed Apollo 20. Belt-tightening budget cuts soon led NASA to cut Apollo 18 and 19 as well, but keep three extended/Lunar Rover missions. Apollo 13 encountered an in-flight spacecraft failure and had to abort its lunar landing in April 1970, returning its crew safely but temporarily grounding the program again. It resumed with four successful landings on Apollo 14 (February 1971), Apollo 15 (July 1971), Apollo 16 (April 1972), and Apollo 17 (December 1972). Question: When was the second landing on the Moon successful?

Ex Output:
November 1969

Ex Input:
Passage: The Qing showed that the Manchus valued military skills in propaganda targeted towards the Ming military to get them to defect to the Qing, since the Ming civilian political system discriminated against the military. The three Liaodong Han Bannermen officers who played a massive role in the conquest of southern China from the Ming were Shang Kexi, Geng Zhongming, and Kong Youde and they governed southern China autonomously as viceroys for the Qing after their conquests. Normally the Manchu Bannermen acted only as reserve forces or in the rear and were used predominantly for quick strikes with maximum impact, so as to minimize ethnic Manchu losses; instead, the Qing used defected Han Chinese troops to fight as the vanguard during the entire conquest of China. Question: Who were the three Liandong Han bannermen who were instrumental in the taking of southern China?

Ex Output:
Shang Kexi, Geng Zhongming, and Kong Youde
