Input: Read this: It is widely assumed that architectural success was the product of a process of trial and error, with progressively less trial and more replication as the results of the process proved increasingly satisfactory. What is termed vernacular architecture continues to be produced in many parts of the world. Indeed, vernacular buildings make up most of the built world that people experience every day. Early human settlements were mostly rural. Due to a surplus in production the economy began to expand resulting in urbanization thus creating urban areas which grew and evolved very rapidly in some cases, such as that of Catal Hoyuk in Anatolia and Mohenjo Daro of the Indus Valley Civilization in modern-day Pakistan.
Question: Why did the economy begin to expand?

Output: a surplus in production

QUES: A 2011 discovery in the Canadian province of New Brunswick uncovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago. Wood can be dated by carbon dating and in some species by dendrochronology to make inferences about when a wooden object was created.
What year were the earliest plants that grew wood discovered?

ANS: 2011

The Sumerians developed a complex system of metrology c. 4000 BC. This advanced metrology resulted in the creation of arithmetic, geometry, and algebra. From c. 2600 BC onwards, the Sumerians wrote multiplication tables on clay tablets and dealt with geometrical exercises and division problems. The earliest traces of the Babylonian numerals also date back to this period. The period c. 2700 2300 BC saw the first appearance of the abacus, and a table of successive columns which delimited the successive orders of magnitude of their sexagesimal number system. The Sumerians were the first to use a place value numeral system. There is also anecdotal evidence the Sumerians may have used a type of slide rule in astronomical calculations. They were the first to find the area of a triangle and the volume of a cube.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of math did the Sumerians invent by the 26th century BC?
Ah, so.. unanswerable

Question: Qado or lunch is often elaborate. Varieties of bariis (rice), the most popular probably being basmati, usually serve as the main dish. Spices like cumin, cardamom, cloves, cinnamon, and garden sage are used to aromatize these different rice delicacies. Somalis eat dinner as late as 9 pm.

Input: Read this: Think-tanks such as the World Pensions Council have also argued that European legislators have pushed somewhat dogmatically for the adoption of the Basel II recommendations, adopted in 2005, transposed in European Union law through the Capital Requirements Directive (CRD), effective since 2008. In essence, they forced European banks, and, more importantly, the European Central Bank itself e.g. when gauging the solvency of financial institutions, to rely more than ever on standardised assessments of credit risk marketed by two non-European private agencies: Moody's and S&P.
Question: What said that agencies had to start using Moody's and S&P to assess financial institutions?

Output:
the Basel II recommendations
