Input: Read this: Copper is synthesized in massive stars and is present in the Earth's crust at a concentration of about 50 parts per million (ppm), where it occurs as native copper or in minerals such as the copper sulfides chalcopyrite and chalcocite, the copper carbonates azurite and malachite, and the copper(I) oxide mineral cuprite. The largest mass of elemental copper discovered weighed 420 tonnes and was found in 1857 on the Keweenaw Peninsula in Michigan, US. Native copper is a polycrystal, with the largest described single crystal measuring 4.43.23.2 cm.
Question: How large was the smallest find of copper?

Output: unanswerable

QUES: After Cao's defeat at the naval Battle of Red Cliffs in 208 AD, China was divided into three spheres of influence, with Cao Cao dominating the north, Sun Quan (182252 AD) dominating the south, and Liu Bei (161223 AD) dominating the west. Cao Cao died in March 220 AD. By December his son Cao Pi (187226 AD) had Emperor Xian relinquish the throne to him and is known posthumously as Emperor Wen of Wei. This formally ended the Han dynasty and initiated an age of conflict between three states: Cao Wei, Eastern Wu, and Shu Han.

What state was in a conflict with Eastern Wu, and Shu Han?
What is the answer?
ANS: Cao Wei

QUES: As is known from the "Sumerian Farmer's Almanac", after the flood season and after the Spring Equinox and the Akitu or New Year Festival, using the canals, farmers would flood their fields and then drain the water. Next they made oxen stomp the ground and kill weeds. They then dragged the fields with pickaxes. After drying, they plowed, harrowed, and raked the ground three times, and pulverized it with a mattock, before planting seed. Unfortunately the high evaporation rate resulted in a gradual increase in the salinity of the fields. By the Ur III period, farmers had switched from wheat to the more salt-tolerant barley as their principal crop.
How many times did Sumerian farmers plow, harrow and rake the ground?

ANS: three times

Just as the navigational approach would require programs to loop in order to collect records, the relational approach would require loops to collect information about any one record. Codd's solution to the necessary looping was a set-oriented language, a suggestion that would later spawn the ubiquitous SQL. Using a branch of mathematics known as tuple calculus, he demonstrated that such a system could support all the operations of normal databases (inserting, updating etc.) as well as providing a simple system for finding and returning sets of data in a single operation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What computer language lost popularity as a result of the looping problem?
Ah, so.. unanswerable

Question: The Rev. Theodore Hesburgh, C.S.C., (19172015) served as president for 35 years (195287) of dramatic transformations. In that time the annual operating budget rose by a factor of 18 from $9.7 million to $176.6 million, and the endowment by a factor of 40 from $9 million to $350 million, and research funding by a factor of 20 from $735,000 to $15 million. Enrollment nearly doubled from 4,979 to 9,600, faculty more than doubled 389 to 950, and degrees awarded annually doubled from 1,212 to 2,500.
Try to answer this question if possible: During what years was Theodor Hesburgh president of Notre Dame?
Answer: 195287

Input: Read this: Not all of these cultural elements characteristic of the Neolithic appeared everywhere in the same order: the earliest farming societies in the Near East did not use pottery. In other parts of the world, such as Africa, South Asia and Southeast Asia, independent domestication events led to their own regionally distinctive Neolithic cultures that arose completely independent of those in Europe and Southwest Asia. Early Japanese societies and other East Asian cultures used pottery before developing agriculture.
Question: What did the use of pottery help early African societies develop?

Output:
unanswerable
