Problem: Nutrition:

Carnivore and herbivore diets are contrasting, with basic nitrogen and carbon proportions vary for their particular foods. "The nitrogen content of plant tissues averages about 2%, while in fungi, animals, and bacteria it averages about 5% to 10%." Many herbivores rely on bacterial fermentation to create digestible nutrients from indigestible plant cellulose, while obligate carnivores must eat animal meats to obtain certain vitamins or nutrients their bodies cannot otherwise synthesize. All animals' diets must provide sufficient amounts of the basic building blocks they need, up to the point where their particular biology can synthesize the rest. Animal tissue contains chemical compounds, such as water, carbohydrates (sugar, starch, and fiber), amino acids (in proteins), fatty acids (in lipids), and nucleic acids (DNA and RNA). These compounds in turn consist of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese, and so on. All of these chemical compounds and elements occur in various forms and combinations (e.g. hormones, vitamins, phospholipids, hydroxyapatite).

Other than nitrogen, what other element varies greatly between a carnivore and herbivore diet?
---
A: carbon


Problem: Despite significant European success during the 1970s and early 1980s, the late '80s had marked a low point for English football. Stadiums were crumbling, supporters endured poor facilities, hooliganism was rife, and English clubs were banned from European competition for five years following the Heysel Stadium disaster in 1985. The Football League First Division, which had been the top level of English football since 1888, was well behind leagues such as Italy's Serie A and Spain's La Liga in attendances and revenues, and several top English players had moved abroad.
What did English players do after the ban?
---
Answer: moved abroad


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was originally known as the Province of Carolina. The northern and southern parts of the original province separated in 1729. Originally settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements, but by 1718 the pirates had been captured and killed. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker, English and German immigrants. The colonists generally supported the American Revolution, as the number of Loyalists was smaller than in some other colonies.
North carolina and Sounth Carolina together were known as what?
A: the Province of Carolina


Context and question: In the United States, their persistent legal challenges prompted a series of state and federal court rulings that reinforced judicial protections for civil liberties. Among the rights strengthened by Witness court victories in the United States are the protection of religious conduct from federal and state interference, the right to abstain from patriotic rituals and military service, the right of patients to refuse medical treatment, and the right to engage in public discourse. Similar cases in their favor have been heard in Canada.
Was it in the US or Canada that Witnesses first gained the right to abstain from patriotic rituals?
Answer: unanswerable


Question: Development of the methods used in modern printed circuit boards started early in the 20th century. In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented a print-and-etch method in Britain, and in the United States Max Schoop obtained a patent to flame-spray metal onto a board through a patterned mask. Charles Ducas in 1927 patented a method of electroplating circuit patterns.
Is there an answer to this question: In Germany Max Schoop obtained a patent to do what?

Answer: unanswerable

Forests cover 24 percent of Oklahoma and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses. Where rainfall is sparse in the western regions of the state, shortgrass prairie and shrublands are the most prominent ecosystems, though pinyon pines, red cedar (junipers), and ponderosa pines grow near rivers and creek beds in the far western reaches of the panhandle. Southwestern Oklahoma contains many rare, disjunct species including sugar maple, bigtooth maple, nolina and southern live oak.
How much of Oklahoma is covered in forests?
A:
24 percent
