In 2015, fragments of a very early Quran, dating back to 1370 years ago, were discovered in the library of the University of Birmingham, England. According to the tests carried out by Oxford University Radiocarbon Accelerator Unit, "with a probability of more than 95%, the parchment was from between 568 and 645". The manuscript is written in Hijazi script, an early form of written Arabic. This is possibly the earliest extant exemplar of the Quran, but as the tests allow a range of possible dates, it cannot be said with certainty which of the existing versions is the oldest. Saudi scholar Saud al-Sarhan has expressed doubt over the age of the fragments as they contain dots and chapter separators that are believed to have originated later.

How many years old were the Quran fragments discovered in Birmingham in 2015?
Answer: 1370


Problem: Johnson's impeachment was perceived to have done great damage to the presidency, which came to be almost subordinate to Congress. Some believed that the president would become a mere figurehead, with the Speaker of the House of Representatives becoming a de facto Prime Minister. Grover Cleveland, the first Democratic President following Johnson, attempted to restore the power of his office. During his first term, he vetoed over four hundred bills—twice as many bills as his twenty-one predecessors combined. He also began to suspend bureaucrats who were appointed as a result of the patronage system, replacing them with more "deserving" individuals. The Senate, however, refused to confirm many new nominations, instead demanding that Cleveland turn over the confidential records relating to the suspensions. Cleveland steadfastly refused, asserting, "These suspensions are my executive acts ... I am not responsible to the Senate, and I am unwilling to submit my actions to them for judgment." Cleveland's popular support forced the Senate to back down and confirm the nominees. Furthermore, Congress finally repealed the controversial Tenure of Office Act that had been passed during the Johnson Administration. Overall, this meant that Cleveland's Administration marked the end of presidential subordination.
Who was the first president to veto over 400 bills?
The answer is the following: Grover Cleveland


The Bibliothèque nationale et universitaire (BNU) is, with its collection of more than 3,000,000 titles, the second largest library in France after the Bibliothèque nationale de France. It was founded by the German administration after the complete destruction of the previous municipal library in 1871 and holds the unique status of being simultaneously a students' and a national library. The Strasbourg municipal library had been marked erroneously as "City Hall" in a French commercial map, which had been captured and used by the German artillery to lay their guns. A librarian from Munich later pointed out "...that the destruction of the precious collection was not the fault of a German artillery officer, who used the French map, but of the slovenly and inaccurate scholarship of a Frenchman."
What is the second largest library in France? 
Bibliothèque nationale et universitaire


Input: Hellenistic period
Throughout the Hellenistic world, these Greco-Macedonian colonists considered themselves by and large superior to the native "barbarians" and excluded most non-Greeks from the upper echelons of courtly and government life. Most of the native population was not Hellenized, had little access to Greek culture and often found themselves discriminated against by their Hellenic overlords. Gymnasiums and their Greek education, for example, were for Greeks only. Greek cities and colonies may have exported Greek art and architecture as far as the Indus, but these were mostly enclaves of Greek culture for the transplanted Greek elite. The degree of influence that Greek culture had throughout the Hellenistic kingdoms was therefore highly localized and based mostly on a few great cities like Alexandria and Antioch. Some natives did learn Greek and adopt Greek ways, but this was mostly limited to a few local elites who were allowed to retain their posts by the Diadochi and also to a small number of mid-level administrators who acted as intermediaries between the Greek speaking upper class and their subjects. In the Seleucid empire for example, this group amounted to only 2.5 percent of the official class.

What are the areas of concentration from where Greek culture eminates?
Output: highly localized


Input: Article: A CD is read by focusing a 780 nm wavelength (near infrared) semiconductor laser housed within the CD player, through the bottom of the polycarbonate layer. The change in height between pits and lands results in a difference in the way the light is reflected. By measuring the intensity change with a photodiode, the data can be read from the disc. In order to accommodate the spiral pattern of data, the semiconductor laser is placed on a swing arm within the disc tray of any CD player. This swing arm allows the laser to read information from the centre to the edge of a disc, without having to interrupt the spinning of the disc itself.

Now answer this question: Where is the semiconductor laser found in a CD player?

Output: on a swing arm


Problem: One study showed that Czech and Slovak lexicons differed by 80 percent, but this high percentage was found to stem primarily from differing orthographies and slight inconsistencies in morphological formation; Slovak morphology is more regular (when changing from the nominative to the locative case, Praha becomes Praze in Czech and Prahe in Slovak). The two lexicons are generally considered similar, with most differences in colloquial vocabulary and some scientific terminology. Slovak has slightly more borrowed words than Czech.
What does Slovak have slightly more of than Czech?
The answer is the following:
borrowed words
