Problem: Infection:

Wound colonization refers to nonreplicating microorganisms within the wound, while in infected wounds, replicating organisms exist and tissue is injured. All multicellular organisms are colonized to some degree by extrinsic organisms, and the vast majority of these exist in either a mutualistic or commensal relationship with the host. An example of the former is the anaerobic bacteria species, which colonizes the mammalian colon, and an example of the latter is various species of staphylococcus that exist on human skin. Neither of these colonizations are considered infections. The difference between an infection and a colonization is often only a matter of circumstance. Non-pathogenic organisms can become pathogenic given specific conditions, and even the most virulent organism requires certain circumstances to cause a compromising infection. Some colonizing bacteria, such as Corynebacteria sp. and viridans streptococci, prevent the adhesion and colonization of pathogenic bacteria and thus have a symbiotic relationship with the host, preventing infection and speeding wound healing.

What are few multicellular organisms colonized to some degree by?

Problem: Two years later, the Emperor Valens, who favored the Arian position, in his turn exiled Athanasius. This time however, Athanasius simply left for the outskirts of Alexandria, where he stayed for only a few months before the local authorities convinced Valens to retract his order of exile. Some early reports state that Athanasius spent this period of exile at his family's ancestral tomb in a Christian cemetery. It was during this period, the final exile, that he is said to have spent four months in hiding in his father's tomb. (Soz., "Hist. Eccl.", VI, xii; Soc., "Hist. Eccl.", IV, xii).
How many years was he exiled?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Quantum dots (QD) are semiconductor nanocrystals that possess unique optical properties. Their emission color can be tuned from the visible throughout the infrared spectrum. This allows quantum dot LEDs to create almost any color on the CIE diagram. This provides more color options and better color rendering than white LEDs since the emission spectrum is much narrower, characteristic of quantum confined states. There are two types of schemes for QD excitation. One uses photo excitation with a primary light source LED (typically blue or UV LEDs are used). The other is direct electrical excitation first demonstrated by Alivisatos et al.
The narrowing of the emission spectrum in Quantum Dot LEDs disallows them to do what?
A: unanswerable


Context and question: Another study examining the health and nutrition literacy status of residents of the lower Mississippi Delta found that 52 percent of participants had a high likelihood of limited literacy skills. While a precise comparison between the NAAL and Delta studies is difficult, primarily because of methodological differences, Zoellner et al. suggest that health literacy rates in the Mississippi Delta region are different from the U.S. general population and that they help establish the scope of the problem of health literacy among adults in the Delta region. For example, only 12 percent of study participants identified the My Pyramid graphic two years after it had been launched by the USDA. The study also found significant relationships between nutrition literacy and income level and nutrition literacy and educational attainment further delineating priorities for the region.
What percentage of people were were found to have a high likelihood of low literacy skills in the Mississippi Delta region?
Answer: 52


Question: The two neurotransmitters that are used most widely in the vertebrate brain are glutamate, which almost always exerts excitatory effects on target neurons, and gamma-aminobutyric acid (GABA), which is almost always inhibitory. Neurons using these transmitters can be found in nearly every part of the brain. Because of their ubiquity, drugs that act on glutamate or GABA tend to have broad and powerful effects. Some general anesthetics act by reducing the effects of glutamate; most tranquilizers exert their sedative effects by enhancing the effects of GABA.
Is there an answer to this question: Which of two neurotransmitters is usually inhibitory?

Answer: gamma-aminobutyric acid (GABA)


Like other historical languages, Old English has been used by scholars and enthusiasts of later periods to create texts either imitating Anglo-Saxon literature or deliberately transferring it to a different cultural context. Examples include Alistair Campbell and J. R. R. Tolkien. A number of websites devoted to Neo-Paganism and Historical re-enactment offer reference material and forums promoting the active use of Old English. By far the most ambitious project[peacock term] is the Old English Wikipedia, but most of the Neo-Old English texts published online bear little resemblance to the historical model and are riddled with very basic grammatical mistakes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What Wikipedia project makes use of the Old English language?
Ah, so..
the Old English Wikipedia
