Problem: Appalachian Mountains:

The Appalachians are characterized by a wealth of large, beautiful deciduous broadleaf (hardwood) trees. Their occurrences are best summarized and described in E. Lucy Braun's 1950 classic, Deciduous Forests of Eastern North America (Macmillan, New York). The most diverse and richest forests are the mixed mesophytic or medium moisture types, which are largely confined to rich, moist montane soils of the southern and central Appalachians, particularly in the Cumberland and Allegheny Mountains, but also thrive in the southern Appalachian coves. Characteristic canopy species are white basswood (Tilia heterophylla), yellow buckeye (Aesculus octandra), sugar maple (Acer saccharum), American beech (Fagus grandifolia), tuliptree (Liriodendron tulipifera), white ash (Fraxinus americana ) and yellow birch (Betula alleganiensis). Other common trees are red maple (Acer rubrum), shagbark and bitternut hickories (Carya ovata and C. cordiformis) and black or sweet birch (Betula lenta ). Small understory trees and shrubs include flowering dogwood (Cornus florida), hophornbeam (Ostrya virginiana), witch-hazel (Hamamelis virginiana) and spicebush (Lindera benzoin). There are also hundreds of perennial and annual herbs, among them such herbal and medicinal plants as American ginseng (Panax quinquefolius), goldenseal (Hydrastis canadensis), bloodroot (Sanguinaria canadensis) and black cohosh (Cimicifuga racemosa).

Problem: The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when the first plats for the village were filed. In 1855, nominal land settlements were established. On January 14, 1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of trustees managing the city. The town of Seattle was disincorporated January 18, 1867 and remained a mere precinct of King County until late 1869, when a new petition was filed and the city was re-incorporated December 2, 1869 with a Mayor-council government. The corporate seal of the City of Seattle carries the date "1869" and a likeness of Chief Sealth in left profile.
What type of governing body did Seattle have in 1869?

Answer: Mayor-council

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions. Sometimes the status of great powers is formally recognized in conferences such as the Congress of Vienna or an international structure such as the United Nations Security Council (China, France, Russia, the United Kingdom and the United States serve as the body's five permanent members). At the same time the status of great powers can be informally recognized in a forum such as the G7 which consists of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States of America.
What spatial aspects are Canada, France, Germany, Italy, Japan, the United Kingdom and the United States a part of?
A: unanswerable

Context and question: Modern geology, like modern chemistry, gradually evolved during the 18th and early 19th centuries. Benoit de Maillet and the Comte de Buffon saw the Earth as much older than the 6,000 years envisioned by biblical scholars. Jean-Etienne Guettard and Nicolas Desmarest hiked central France and recorded their observations on some of the first geological maps. Aided by chemical experimentation, naturalists such as Scotland's John Walker, Sweden's Torbern Bergman, and Germany's Abraham Werner created comprehensive classification systems for rocks and mineralsa collective achievement that transformed geology into a cutting edge field by the end of the eighteenth century. These early geologists also proposed a generalized interpretations of Earth history that led James Hutton, Georges Cuvier and Alexandre Brongniart, following in the steps of Steno, to argue that layers of rock could be dated by the fossils they contained: a principle first applied to the geology of the Paris Basin. The use of index fossils became a powerful tool for making geological maps, because it allowed geologists to correlate the rocks in one locality with those of similar age in other, distant localities. Over the first half of the 19th century, geologists such as Charles Lyell, Adam Sedgwick, and Roderick Murchison applied the new technique to rocks throughout Europe and eastern North America, setting the stage for more detailed, government-funded mapping projects in later decades.
What are used to create geological maps?
Answer: index fossils

QUES: Several systems were proposed as the new standard for the US, including the Japanese MUSE system, but all were rejected by the FCC because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC.

What was decreasing and consuming a lot of bandwidth?
