Input: Aircraft carrier
On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-WWII Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.

What can a "bolt" prevent an aircraft from doing?
Output: crashing into aircraft on the forward deck

Input: Article: The Beijing Olympic Organizing Committee sent out a team of 30 unarmed attendants selected from the People's Armed Police to escort the flame throughout its journey. According to Asian Times, sworn in as the "Beijing Olympic Games Sacred Flame Protection Unit" during a ceremony in August 2007, their main job is to keep the Olympic flame alight throughout the journey and to assist in transferring the flame between the torches, the lanterns and the cauldrons. They wear matching blue tracksuits and are intended to accompany the torch every step of the way. One of the torch attendants, dubbed "Second Right Brother," has developed a significant online fan-base, particularly among China's female netizens.

Now answer this question: How many attendants were used from the People's Armed Police for the flame's entire journey?

Output: 30

Article: Buddhism began to spread throughout Japan during the Heian period, primarily through two major esoteric sects, Tendai and Shingon. Tendai originated in China and is based on the Lotus Sutra, one of the most important sutras of Mahayana Buddhism; Saicho was key to its transmission to Japan. Shingon is the Japanese transmission of the Chinese Chen Yen school. Shingon, brought to Japan by the monk Kukai, emphasizes Esoteric Buddhism. Both Kukai and Saicho aimed to connect state and religion and establish support from the aristocracy, leading to the notion of 'aristocratic Buddhism'. An important element of Tendai doctrine was the suggestion that enlightenment was accessible to "every creature". Saicho also sought independent ordination for Tendai monks. A close relationship developed between the Tendai monastery complex on Mount Hiei and the imperial court in its new capital at the foot of the mountain. As a result, Tendai emphasized great reverence for the emperor and the nation. Kammu himself was a notable patron of the otherworldly Tendai sect, which rose to great power over the ensuing centuries. Kukai greatly impressed the emperors who succeeded Emperor Kammu, and also generations of Japanese, not only with his holiness but also with his poetry, calligraphy, painting, and sculpture. Shingon, through its use of "rich symbols, rituals and mandalas" held a wide-ranging appeal.

Question: What religion spread during the Heian period?
Ans: Buddhism

The problem: Answer a question about this article:
Feynman attended Far Rockaway High School, a school in Far Rockaway, Queens also attended by fellow Nobel laureates Burton Richter and Baruch Samuel Blumberg. Upon starting high school, Feynman was quickly promoted into a higher math class. An unspecified school-administered IQ test estimated his IQ at 123high, but "merely respectable" according to biographer James Gleick. When he turned 15, he taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus. In high school he was developing the mathematical intuition behind his Taylor series of mathematical operators. Before entering college, he was experimenting with and deriving mathematical topics such as the half-derivative using his own notation.
What did Feyman derive before he went to college?
****
The answer: half-derivative
