According to his autobiography, Avicenna had memorised the entire Quran by the age of 10. He learned Indian arithmetic from an Indian greengrocer,ءMahmoud Massahi and he began to learn more from a wandering scholar who gained a livelihood by curing the sick and teaching the young. He also studied Fiqh (Islamic jurisprudence) under the Sunni Hanafi scholar Ismail al-Zahid. Avicenna was taught some extent of philosophy books such as Introduction (Isagoge)'s Porphyry (philosopher), Euclid's Elements, Ptolemy's Almagest by an unpopular philosopher, Abu Abdullah Nateli, who claimed philosophizing.
What had Avicenna memorized by the age of 10?
Quran


Input: Wood
Abnormal discoloration of wood often denotes a diseased condition, indicating unsoundness. The black check in western hemlock is the result of insect attacks. The reddish-brown streaks so common in hickory and certain other woods are mostly the result of injury by birds. The discoloration is merely an indication of an injury, and in all probability does not of itself affect the properties of the wood. Certain rot-producing fungi impart to wood characteristic colors which thus become symptomatic of weakness; however an attractive effect known as spalting produced by this process is often considered a desirable characteristic. Ordinary sap-staining is due to fungal growth, but does not necessarily produce a weakening effect.

What causes the black checked pattern in the wood of western hemlocks?
Output: insect attacks


Input: Article: The cocoa industry was accused of profiting from child slavery and trafficking. The European Cocoa Association dismissed these accusations as "false and excessive" and the industry said the reports were not representative of all areas. Later the industry acknowledged the working conditions for children were unsatisfactory and children's rights were sometimes violated and acknowledged the claims could not be ignored. In a BBC interview, the ambassador for Ivory Coast to the United Kingdom called these reports of widespread use of slave child labour by 700,000 cocoa farmers as absurd and inaccurate.

Now answer this question: Who claimed these reports as being inaccurate?

Output: ambassador for Ivory Coast to the United Kingdom


Article: From 1920, Eisenhower served under a succession of talented generals – Fox Conner, John J. Pershing, Douglas MacArthur and George Marshall. He first became executive officer to General Conner in the Panama Canal Zone, where, joined by Mamie, he served until 1924. Under Conner's tutelage, he studied military history and theory (including Carl von Clausewitz's On War), and later cited Conner's enormous influence on his military thinking, saying in 1962 that "Fox Conner was the ablest man I ever knew." Conner's comment on Eisenhower was, "[He] is one of the most capable, efficient and loyal officers I have ever met." On Conner's recommendation, in 1925–26 he attended the Command and General Staff College at Fort Leavenworth, Kansas, where he graduated first in a class of 245 officers. He then served as a battalion commander at Fort Benning, Georgia, until 1927.

Question: What notable military treatise was authored by von Clausewitz?
Ans: On War


Here is a question about this article: Neptune has a number of known trojan objects occupying both the Sun–Neptune L4 and L5 Lagrangian points—gravitationally stable regions leading and trailing Neptune in its orbit, respectively. Neptune trojans can be viewed as being in a 1:1 resonance with Neptune. Some Neptune trojans are remarkably stable in their orbits, and are likely to have formed alongside Neptune rather than being captured. The first and so far only object identified as associated with Neptune's trailing L5 Lagrangian point is 2008 LC18. Neptune also has a temporary quasi-satellite, (309239) 2007 RW10. The object has been a quasi-satellite of Neptune for about 12,500 years and it will remain in that dynamical state for another 12,500 years.
What is the answer to this question: What is the only object identified with Neptune's trailing L5 Lagrangian point?
****
So... 2008 LC18


Article: The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration. In 1876 Lord Kelvin had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators. In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in the 1920s, Vannevar Bush and others developed mechanical differential analyzers.

Question: What type of mechanisms did the differential analyzer use?
Ans:
wheel-and-disc
