Problem: High-definition television:

HDTV can be recorded to D-VHS (Digital-VHS or Data-VHS), W-VHS (analog only), to an HDTV-capable digital video recorder (for example DirecTV's high-definition Digital video recorder, Sky HD's set-top box, Dish Network's VIP 622 or VIP 722 high-definition Digital video recorder receivers, or TiVo's Series 3 or HD recorders), or an HDTV-ready HTPC. Some cable boxes are capable of receiving or recording two or more broadcasts at a time in HDTV format, and HDTV programming, some included in the monthly cable service subscription price, some for an additional fee, can be played back with the cable company's on-demand feature.

Sky HD's set-top box, TiVo's Series 3, and Dish Network's VIP 622 aren't examples of what?

Problem: Improved sanitation in the developing world is a global need, but a neglected priority as shown by the data collected by the Joint Monitoring Programme for Water Supply and Sanitation (JMP) of UNICEF and WHO. This program is tasked to monitor progress towards the Millennium Development Goal (MDG) relating to drinking water and sanitation. About one billion people have no sanitation facility whatsoever and continue to defecate in gutters, behind bushes or in open water bodies, with no dignity or privacy - which is called open defecation and which poses significant health risks. India is the country with the highest number of people practicing open defecation: around 600 million people. India has also become a focus country for the foundation's sanitation activities which has become evident since the "Reinvent the Toilet Fair" in Delhi, India in March 2014.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by metallic bonding character. An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds are alloys with a defined stoichiometry and crystal structure. Zintl phases are also sometimes considered alloys depending on bond types (see also: Van Arkel-Ketelaar triangle for information on classifying bonding in binary compounds).
What are alloys defined by?
A: metallic bonding character

Context and question: Some Europeans living among Indigenous Americans were called "white Indians". They "lived in native communities for years, learned native languages fluently, attended native councils, and often fought alongside their native companions." More numerous and typical were traders and trappers, who married Indigenous American women from tribes on the frontier and had families with them. Some traders, who kept bases in the cities, had what ware called "country wives" among Indigenous Americans, with legal European-American wives and children at home in the city. Not all abandoned their "natural" mixed-race children. Some arranged for sons to be sent to European-American schools for their education.
Where were legal wives usually kept?
Answer: in the city

Question: 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.
Is there an answer to this question: Located in the McMurray Formation, what is the smallest deposit of natural bitumen known as?

Answer: unanswerable

Problem: Yale University:

The Yale Report of 1828 was a dogmatic defense of the Latin and Greek curriculum against critics who wanted more courses in modern languages, mathematics, and science. Unlike higher education in Europe, there was no national curriculum for colleges and universities in the United States. In the competition for students and financial support, college leaders strove to keep current with demands for innovation. At the same time, they realized that a significant portion of their students and prospective students demanded a classical background. The Yale report meant the classics would not be abandoned. All institutions experimented with changes in the curriculum, often resulting in a dual track. In the decentralized environment of higher education in the United States, balancing change with tradition was a common challenge because no one could afford to be completely modern or completely classical. A group of professors at Yale and New Haven Congregationalist ministers articulated a conservative response to the changes brought about by the Victorian culture. They concentrated on developing a whole man possessed of religious values sufficiently strong to resist temptations from within, yet flexible enough to adjust to the 'isms' (professionalism, materialism, individualism, and consumerism) tempting him from without. William Graham Sumner, professor from 1872 to 1909, taught in the emerging disciplines of economics and sociology to overflowing classrooms. He bested President Noah Porter, who disliked social science and wanted Yale to lock into its traditions of classical education. Porter objected to Sumner's use of a textbook by Herbert Spencer that espoused agnostic materialism because it might harm students.

What changes were the professors and ministers responding to?

A:
Victorian culture
