Ex Input:
Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter . <sep>Which planet reaches Darwin IV by traveling at 20% the speed of light?<sep>Alien Planet with Von Braun

In the rest of the world, China's supreme sage, Kongfuzi (K'ung Fu-tzu), is better known by the romanized name "Confucius." He was born in 551 b.c. in what is now Shandong Province in eastern China. So profound was his influence that eleven Chinese emperors made pilgrimages to the birthplace of the Great Teacher. You, too, can pay your respects at the vast temple raised on the site of his home in the small town of Qufu (Chufu), and at his tomb in the woods just to the north. The classics of Confucius, while seldom addressing spiritual and metaphysical matters, set standards for social and political conduct that still underlie many of the Chinese ways of doing and perceiving. Confucius laid great stress on the proper and harmonious relationships between ruler and subject, parent and child, teacher and student, the individual and the state. These relationships were deemed to be hierarchical and dictatorial. If the order was disturbed, dire consequences inevitably resulted. The son who disobeyed the father would bring disaster upon himself and his family, just as the emperor who defied the "mandate of heaven" or ignored the good of the empire brought ruin upon the nation. Over the centuries Confucius has suffered more changes of fortune than probably any other philosopher. Honored soon after his death as the greatest of scholars, he was later revered as semi-divine; you can still visit temples to Confucius in many Chinese cities. During the Cultural Revolution (19661976), however, he was denounced as a counter-revolutionary force. It was only after the death of Chairman Mao (1976) and the opening of China to the outside world under more progressive reformers that Confucius, too, was "rehabilitated." Unlike Confucius, about whose life many specific and even colorful details are known, the philosopher Laozi (Lao Tse or Lao-Tzu) is an enigma. Estimates of his date of birth vary by well over a century. One legend even says he taught the young Confucius. Laozi is immortalized by his book of thoughts on man, nature, and the universe, Daodejing ("The Way and Its Power"), which became the major text of China's greatest indigenous religion, Daoism (Taoism). With its emphasis on nature, intuition, the individual, paradox ("The knowledge which is not knowledge"), and the cosmic flow known as "The Way," Daoism became the religion of artists and philosophers. After the death of Confucius, the Zhou Dynasty entered a period of strife known as the "Warring States" period (475221 b.c.). <sep>Do we know the exact date of Laozi's birth?<sep>Yes

The second major point on which the principals had agreed on March 10 was the need to crack down on terrorist organizations and curtail their fund-raising. The embassy bombings of 1998 had focused attention on al Qaeda's finances. One result had been the creation of an NSC-led interagency committee on terrorist financing. On its recommendation, the President had designated Bin Laden and al Qaeda as subject to sanctions under the International Emergency Economic Powers Act. This gave theTreasury Department's Office of Foreign Assets Control (OFAC) the ability to search for and freeze any Bin Laden or al Qaeda assets that reached the U.S. financial system. But since OFAC had little information to go on, few funds were frozen. In July 1999, the President applied the same designation to the Taliban for harboring Bin Laden. Here, OFAC had more success. It blocked more than $34 million in Taliban assets held in U.S. banks. Another $215 million in gold and $2 million in demand deposits, all belonging to the Afghan central bank and held by the Federal Reserve Bank of New York, were also frozen. After October 1999, when the State Department formally designated al Qaeda a "foreign terrorist organization," it became the duty of U.S. banks to block its transactions and seize its funds. Neither this designation nor UN sanctions had much additional practical effect; the sanctions were easily circumvented, and there were no multilateral mechanisms to ensure that other countries' financial systems were not used as conduits for terrorist funding. Attacking the funds of an institution, even the Taliban, was easier than finding and seizing the funds of a clandestine worldwide organization like al Qaeda. Although the CIA's Bin Laden unit had originally been inspired by the idea of studying terrorist financial links, few personnel assigned to it had any experience in financial investigations. Any terrorist-financing intelligence appeared to have been collected collaterally, as a consequence of gathering other intelligence. This attitude may have stemmed in large part from the chief of this unit, who did not believe that simply following the money from point A to point B revealed much about the terrorists' plans and intentions. As a result, the CIA placed little emphasis on terrorist financing. Nevertheless, the CIA obtained a general understanding of how al Qaeda raised money. <sep>The OFAC tried to freeze which terrorist organizations funding?<sep>Hamas
