QUES: Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson's example shows that new models for research groups are needed, especially for those that include extensive field research.

What didn't Hutchinson's group research?

QUES: 
 France: The torch relay leg in Paris, held on April 7, began on the first level of the Eiffel Tower and finished at the Stade Charléty. The relay was initially supposed to cover 28 km, but it was shortened at the demand of Chinese officials following widespread protests by pro-Tibet and human rights activists, who repeatedly attempted to disrupt, hinder or halt the procession. A scheduled ceremony at the town hall was cancelled at the request of the Chinese authorities, and, also at the request of Chinese authorities, the torch finished the relay by bus instead of being carried by athletes. Paris City officials had announced plans to greet the Olympic flame with peaceful protest when the torch was to reach the French capital. The city government attached a banner reading "Paris defends human rights throughout the world" to the City Hall, in an attempt to promote values "of all humanity and of human rights." Members from Reporters Without Borders turned out in large numbers to protest. An estimated 3,000 French police protected the Olympic torch relay as it departed from the Eiffel Tower and criss-crossed Paris amid threat of protests. Widespread pro-Tibet protests, including an attempt by more than one demonstrator to extinguish the flame with water or fire extinguishers, prompted relay authorities to put out the flame five times (according to the police authorities in Paris) and load the torch onto a bus, at the demand of Chinese officials. This was later denied by the Chinese Ministry of Foreign Affairs, despite video footage broadcast by French television network France 2 which showed Chinese flame attendants extinguishing the torch. Backup flames are with the relay at all times to relight the torch. French judoka and torchbearer David Douillet expressed his annoyance at the Chinese flame attendants who extinguished the torch which he was about to hand over to Teddy Riner: "I understand they're afraid of everything, but this is just annoying. They extinguished the flame despite the fact that there was no risk, and they could see it and they knew it. I don't know why they did it."
What city in France did the torch relay start at?

ANS: Paris


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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"):  Late papermakers added alum to help in what process?
Ah, so.. unanswerable

Context and question: The earliest archaeological artifacts in Iran, like those excavated at the Kashafrud and Ganj Par sites, attest to a human presence in Iran since the Lower Paleolithic era, c. 800,000–200,000 BC. Iran's Neanderthal artifacts from the Middle Paleolithic period, c. 200,000–40,000 BC, have been found mainly in the Zagros region, at sites such as Warwasi and Yafteh Cave.[page needed] Around 10th to 8th millennium BC, early agricultural communities such as Chogha Golan and Chogha Bonut began to flourish in Iran, as well as Susa and Chogha Mish developing in and around the Zagros region.[page needed]
How long ago were the earliest artifacts from that were evidence of humans in Iran?
Answer:
the Lower Paleolithic era, c. 800,000–200,000 BC
