Problem: History of science:

The important legacy of this period included substantial advances in factual knowledge, especially in anatomy, zoology, botany, mineralogy, geography, mathematics and astronomy; an awareness of the importance of certain scientific problems, especially those related to the problem of change and its causes; and a recognition of the methodological importance of applying mathematics to natural phenomena and of undertaking empirical research. In the Hellenistic age scholars frequently employed the principles developed in earlier Greek thought: the application of mathematics and deliberate empirical research, in their scientific investigations. Thus, clear unbroken lines of influence lead from ancient Greek and Hellenistic philosophers, to medieval Muslim philosophers and scientists, to the European Renaissance and Enlightenment, to the secular sciences of the modern day. Neither reason nor inquiry began with the Ancient Greeks, but the Socratic method did, along with the idea of Forms, great advances in geometry, logic, and the natural sciences. According to Benjamin Farrington, former Professor of Classics at Swansea University:

What scientific theory was created by the Greeks?

A: the Socratic method

Problem: Paper:

Much of the early paper made from wood pulp contained significant amounts of alum, a variety of aluminium sulfate salts that is significantly acidic. Alum was added to paper to assist in sizing, making it somewhat water resistant so that inks did not "run" or spread uncontrollably. Early papermakers did not realize that the alum they added liberally to cure almost every problem encountered in making their product would eventually be detrimental. The cellulose fibres that make up paper are hydrolyzed by acid, and the presence of alum would eventually degrade the fibres until the paper disintegrated in a process that has come to be known as "slow fire". Documents written on rag paper were significantly more stable. The use of non-acidic additives to make paper is becoming more prevalent, and the stability of these papers is less of an issue.

What is more of an issue with papers made with non acidic additives?

A: unanswerable

Problem: Paris:

The Paris Region had 5.4 million salaried employees in 2010, of whom 2.2 million were concentrated in 39 poles d'emplois or business districts. The largest of these, in terms of number of employees, is known in French as the QCA, or quartier central des affaires; it is in the western part of the City of Paris, in the 2nd, 8th, 9th, 16th and 18th arrondissements. In 2010 it was the workplace of 500,000 salaried employees, about thirty percent of the salaried employees in Paris and ten percent of those in the Ile-de-France. The largest sectors of activity in the central business district were finance and insurance (16 percent of employees in the district) and business services (15 percent). The district also includes a large concentration of department stores, shopping areas, hotels and restaurants, as well a government offices and ministries.

How many salaried employees lived in the Paris Region in 2010?

A: 5.4 million

Problem: Near East:

The Central Intelligence Agency (CIA) is a quasi-independent agency of the United States Government. It appears to have multiple leadership. On the one hand its director is appointed by the president. It plays a significant role in providing the president with intelligence. On the other hand, Congress oversees its operations through a committee. The CIA was first formed under the National Security Act of 1947 from the army's Office of Strategic Services (OSS), which furnished both military intelligence and clandestine military operations to the army during the crisis of World War II. Many revisions and redefinitions have taken place since then. Although the name of the CIA reflects the original advised intent of Presidents Franklin D. Roosevelt and Harry S. Truman, the government's needs for strategic services have frustrated that intent from the beginning. The press received by the agency in countless articles, novels and other media have tended to create various popular myths; for example, that this agency replaced any intelligence effort other than that of the OSS, or that it contains the central intelligence capability of the United States. Strategic services are officially provided by some 17 agencies called the Intelligence Community. Army intelligence did not come to an end; in fact, all the branches of the Armed Forces retained their intelligence services. This community is currently under the leadership (in addition to all its other leadership) of the Office of the Director of National Intelligence.
