The world's largest deposit of natural bitumen, known as the Athabasca oil sands is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies attribute the oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands, to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta bitumen deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage.

How old are the Athabasca deposits?
---
A: 110 million years

Problem: While successful predation results in a gain of energy, hunting invariably involves energetic costs as well. When hunger is not an issue, in general most predators will not seek to attack prey since the costs outweigh the benefits. For instance, a large predatory fish like a shark that is well fed in an aquarium will typically ignore the smaller fish swimming around it (while the prey fish take advantage of the fact that the apex predator is apparently uninterested). Surplus killing represents a deviation from this type of behaviour. The treatment of consumption in terms of cost-benefit analysis is known as optimal foraging theory, and has been quite successful in the study of animal behavior. In general, costs and benefits are considered in energy gain per unit time, though other factors are also important, such as essential nutrients that have no caloric value but are necessary for survival and health.
In optimal foraging theory, how are costs and benefits measured?
---
Answer: energy gain per unit time

Madonna performed at the Hope for Haiti Now: A Global Benefit for Earthquake Relief concert in January 2010. In April she released her third live album, Sticky & Sweet Tour. It was her first release under Live Nation, but was distributed by Warner Bros. Madonna granted American TV show Glee the rights to her entire catalogue of music, and the producers planned an episode featuring Madonna songs exclusively. Glee: The Music, The Power of Madonna, an EP containing eight cover versions of Madonna songs featured in the episode, was released afterward and debuted at number one on the Billboard 200.
Madonna granted which TV show the rights to her entire catalog of music?
A: Glee

Context and question: FETs are divided into two families: junction FET (JFET) and insulated gate FET (IGFET). The IGFET is more commonly known as a metaloxidesemiconductor FET (MOSFET), reflecting its original construction from layers of metal (the gate), oxide (the insulation), and semiconductor. Unlike IGFETs, the JFET gate forms a pn diode with the channel which lies between the source and drain. Functionally, this makes the n-channel JFET the solid-state equivalent of the vacuum tube triode which, similarly, forms a diode between its grid and cathode. Also, both devices operate in the depletion mode, they both have a high input impedance, and they both conduct current under the control of an input voltage.
What kind of FET is mass produced?
Answer: unanswerable

Question: But in the mid-18th century, during the French Enlightenment, a more ideological use of the term had come into use. In 1765, the author of an anonymous article in a French Enlightenment periodical spoke of "The general love of humanity ... a virtue hitherto quite nameless among us, and which we will venture to call 'humanism', for the time has come to create a word for such a beautiful and necessary thing". The latter part of the 18th and the early 19th centuries saw the creation of numerous grass-roots "philanthropic" and benevolent societies dedicated to human betterment and the spreading of knowledge (some Christian, some not). After the French Revolution, the idea that human virtue could be created by human reason alone independently from traditional religious institutions, attributed by opponents of the Revolution to Enlightenment philosophes such as Rousseau, was violently attacked by influential religious and political conservatives, such as Edmund Burke and Joseph de Maistre, as a deification or idolatry of humanity. Humanism began to acquire a negative sense. The Oxford English Dictionary records the use of the word "humanism" by an English clergyman in 1812 to indicate those who believe in the "mere humanity" (as opposed to the divine nature) of Christ, i.e., Unitarians and Deists. In this polarised atmosphere, in which established ecclesiastical bodies tended to circle the wagons and reflexively oppose political and social reforms like extending the franchise, universal schooling, and the like, liberal reformers and radicals embraced the idea of Humanism as an alternative religion of humanity. The anarchist Proudhon (best known for declaring that "property is theft") used the word "humanism" to describe a "culte, deification de l'humanite" ("worship, deification of humanity") and Ernest Renan in L'avenir de la science: pensees de 1848 ("The Future of Knowledge: Thoughts on 1848") (184849), states: "It is my deep conviction that pure humanism will be the religion of the future, that is, the cult of all that pertains to humanityall of life, sanctified and raised to the level of a moral value."
Is there an answer to this question: What was the criticism of Humanism made by magicians of the time?

Students from the Imperial University organized a widespread student protest against the eunuchs of Emperor Huan's court. Huan further alienated the bureaucracy when he initiated grandiose construction projects and hosted thousands of concubines in his harem at a time of economic crisis. Palace eunuchs imprisoned the official Li Ying () and his associates from the Imperial University on a dubious charge of treason. In 167 AD, the Grand Commandant Dou Wu (d. 168 AD) convinced his son-in-law, Emperor Huan, to release them. However the emperor permanently barred Li Ying and his associates from serving in office, marking the beginning of the Partisan Prohibitions.
When did Dou Wu die?
A:
168 AD
