Sloths are a group of arboreal Neotropical xenarthran mammals, constituting the suborder Folivora. Noted for their slowness of movement, they spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America. They are considered to be most closely related to anteaters, together making up the xenarthran order Pilosa. 
There are six extant sloth species in two genera – Bradypus (three–toed sloths) and Choloepus (two–toed sloths). Despite this traditional naming, all sloths actually have three toes on each rear limb, although two-toed sloths have only two digits on each forelimb. The two groups of sloths are from different, distantly related families, and are thought to have evolved their morphology via parallel evolution from terrestrial ancestors. Besides the extant species, many species of ground sloths ranging up to the size of elephants (like Megatherium) inhabited both North and South America during the Pleistocene Epoch. However, they became extinct during the Quaternary extinction event around 12,000 years ago, together with most large bodied animals in the New World. The extinction correlates in time with the arrival of humans, but climate change has also been suggested to have contributed. Members of an endemic radiation of Caribbean sloths formerly lived in the Greater Antilles.

A library is a collection of materials, books or media that are easily accessible for use and not just for display purposes. It is responsible for housing updated information in order to meet the user's needs on a daily basis. A Library provides physical (hard copies documents) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVDs, CDs and Cassette as well as access to information, music or other content held on bibliographic databases.
A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government, an institution/ schools, a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources. Hence, librarians go an extra mile to meet the user's need by ensuring that their users are satisfied with the information provided. A Librarian is one person who is expected to be very vibrant and innovative especially in this digital world.Library buildings often provide quiet and conducive areas for studying, as well as common areas for group study and collaboration, and may provide public facilities for access to their electronic resources for instance Computers and Desktop and access to the Internet. The library's clientele and therefore the services offered vary depending on its type: users of a public library have different needs from those of a special library, for example. Libraries may also be community hubs, where programs are delivered and people engage in lifelong learning.

Lettuce (Lactuca sativa) is an annual plant of the daisy family, Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds.  Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, the celtuce (asparagus lettuce) (t: 萵苣; s: 莴苣; woju), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption.  Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world.  World production of lettuce and chicory for  2017 was 27 million tonnes, 56% of which came from China.Lettuce was originally farmed by the ancient Egyptians, who transformed it from a plant whose seeds were used to create oil into an important food crop raised for its succulent leaves and oil-rich seeds. Lettuce spread to the Greeks and Romans; the latter gave it the name lactuca, from which the English lettuce is derived. By 50 AD, many types were described, and lettuce appeared often in medieval writings, including several herbals. The 16th through 18th centuries saw the development of many varieties in Europe, and by the mid-18th century cultivars were described that can still be found in gardens.

Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down—to the level of the skin or otherwise. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair. A man is called clean-shaven if he has had his beard entirely removed.Both men and women sometimes shave their chest hair, abdominal hair, leg hair, underarm hair, pubic hair, or any other body hair. Head shaving is much more common among men. It is often associated with religious practice, the armed forces and some competitive sports such as swimming, running, and extreme sports. Historically, head shaving has also been used to humiliate, punish and show submission to an authority, and in more recent history also as part of fund-raising efforts, particularly for cancer research organizations and charitable organizations which serve cancer patients. The shaving of head hair is also sometimes done by cancer patients when their treatment may result in hair loss.


== History ==

Before the advent of razors, hair was sometimes removed using two shells to pull the hair out or using water and a sharp tool. Around 3000 BC when copper tools were developed, copper razors were invented.  The idea of an aesthetic approach to personal hygiene may have begun at this time, though Egyptian priests may have practiced something similar to this earlier.

Finland (Finnish: Suomi [ˈsuo̯mi] (listen); Swedish: Finland [ˈfɪ̌nland] (listen), Finland Swedish: [ˈfinlɑnd]), officially the Republic of Finland (Finnish: Suomen tasavalta, Swedish: Republiken Finland (listen to all)), is a Nordic country in Northern Europe. It shares land borders with Sweden to the west, Russia to the east, Norway to the north, and is defined by the Gulf of Bothnia to the west, and the Gulf of Finland of the Baltic Sea across Estonia to the south. Finland covers an area of 338,455 square kilometres (130,678 sq mi), with a population of 5.5 million. Helsinki is the country's capital and largest city, but together with the neighboring cities of Espoo, Kauniainen and Vantaa, it forms a larger metropolitan area. Finnish, the native language of the Finns, is among the few Finnic languages in the world. The climate varies relative to latitude, from the southern humid continental climate to the northern boreal climate. The land cover is primarily a boreal forest biome, with more than 180,000 recorded lakes.Finland was inhabited around 9000 BC after the Last Glacial Period. The Stone Age introduced several different ceramic styles and cultures. The Bronze Age and Iron Age were characterised by extensive contacts with other cultures in Fennoscandia and the Baltic region. From the late 13th century, Finland gradually became an integral part of Sweden as a consequence of the Northern Crusades.

Penguins (order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galápagos penguin, found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch while swimming underwater. They spend roughly half of their lives on land and the other half in the sea.
Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin live so far south. Several species are found in the temperate zone, but one species, the Galápagos penguin, lives near the Equator.
The largest living species is the emperor penguin (Aptenodytes forsteri): on average, adults are about 1.1 m (3 ft 7 in) tall and weigh 35 kg (77 lb). The smallest penguin species is the little blue penguin (Eudyptula minor), also known as the fairy penguin, which stands around 33 cm (13 in) tall and weighs 1 kg (2.2 lb).

Sweden (; Swedish: Sverige [ˈsvæ̌rjɛ] (listen)), officially the Kingdom of Sweden (Swedish: Konungariket Sverige [ˈkôːnɵŋaˌriːkɛt ˈsvæ̌rjɛ] (listen)), is a Nordic country in Northern Europe. It borders Norway to the west and north, Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund Strait. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union, and the fifth largest country in Europe. The capital city is Stockholm. Sweden has a total population of 10.4 million; and a low population density of 25 inhabitants per square kilometre (65/sq mi). 87% of Swedes live in urban areas, which cover 1.5% of the entire land area. The highest concentration is in the central and southern half of the country.
Sweden is part of the geographical area of Fennoscandia. The climate is in general mild for its northerly latitude due to significant maritime influence. In spite of the high latitude, Sweden often has warm continental summers, being located in between the North Atlantic, the Baltic Sea, and vast Russia.

A yacht  is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies to such vessels that have a cabin with amenities that accommodate overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.The Commercial Yacht Code classifies yachts 79 ft (24 m) and over as large. Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are: commercial—carrying no more than 12 passengers, private—solely for the pleasure of the owner and guests, or by flag, the country under which it is registered. A superyacht (sometimes megayacht) generally refers to any yacht (sail or power) longer than 131 ft (40 m).Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020 there were more than 15,000 yachts of sufficient size to require a professional crew.


== Etymology ==

The term, yacht, originates from the Dutch word jacht (pl. jachten, which means "hunt"), and originally referred to light, fast sailing vessels that the Dutch Republic navy used to pursue pirates and other transgressors around and into the shallow waters of the Low Countries.

Cockroaches (or roaches) are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as pests.
The cockroaches are an ancient group, with ancestors originating during the Carboniferous period, some 300-350 million years ago. Those early ancestors, however, lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects lacking special adaptations (such as the sucking mouthparts of aphids and other true bugs); they have chewing mouthparts and are likely among the most primitive of living Neopteran insects. They are common and hardy insects capable of tolerating a wide range of climates, from Arctic cold to tropical heat. Tropical cockroaches are often much larger than temperate species. Contrary to popular belief, extinct cockroach relatives (Blattoptera) and 'roachoids' such as the Carboniferous Archimylacris and the Permian Apthoroblattina were not as large as the biggest modern species.
Some species, such as the gregarious German cockroach, have an elaborate social structure involving common shelter, social dependence, information transfer and kin recognition.

Earth is the third planet from the Sun and the only astronomical object known to harbor and support life. About 29.2% of Earth's surface is land consisting of continents and islands. The remaining 70.8% is covered with water, mostly by oceans, seas, gulfs, and other salt-water bodies, but also by lakes, rivers, and other freshwater, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years, while its interior remains active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convective mantle that drives plate tectonics.
Earth's atmosphere consists mostly of nitrogen and oxygen. More solar energy is received by tropical regions than polar regions and is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by elevation and proximity to moderating oceans, among other factors. Severe weather, such as tropical cyclones, thunderstorms, and heatwaves, occurs in most areas and greatly impacts life.

Ötzi, also called the Iceman, is the natural mummy of a man who lived between 3400 and 3100 BCE, discovered in September 1991 in the Ötztal Alps (hence the nickname "Ötzi") on the border between Austria and Italy.
Ötzi is believed to have been murdered, due to the discovery of an arrowhead embedded in his left shoulder and various other wounds. The nature of his life and the circumstances of his death are the subject of much investigation and speculation.
He is Europe's oldest known natural human mummy, offering an unprecedented view of Chalcolithic (Copper Age) Europeans. His body and belongings are displayed in the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy.


== Discovery ==

Ötzi was found on 19 September 1991 by two German tourists, at an elevation of 3,210 metres (10,530 ft) on the east ridge of the Fineilspitze in the Ötztal Alps on the Austrian–Italian border, near Similaun mountain and the Tisenjoch pass. When the tourists, Helmut and Erika Simon, first saw the body, they both believed that they had happened upon a recently deceased mountaineer. The next day, a mountain gendarme and the keeper of the nearby Similaunhütte first attempted to remove the body, which was frozen in ice below the torso, using a pneumatic drill and ice-axes, but had to give up due to bad weather. Within a short time, eight groups visited the site, among whom were mountaineers Hans Kammerlander and Reinhold Messner. The body was semi-officially extracted on 22 September and officially salvaged the following day.

A monopoly (from Greek μόνος, mónos, 'single, alone' and πωλεῖν, pōleîn, 'to sell') exists when a specific person or enterprise is the only supplier of a particular commodity. This contrasts with a monopsony which relates to a single entity's control of a market to purchase a good or service, and with oligopoly and duopoly which consists of a few sellers dominating a market. Monopolies are thus characterized by a lack of economic competition to produce the good or service, a lack of viable substitute goods, and the possibility of a high monopoly price well above the seller's marginal cost that leads to a high monopoly profit. The verb monopolise or monopolize refers to the process by which a company gains the ability to raise prices or exclude competitors. In economics, a monopoly is a single seller. In law, a monopoly is a business entity that has significant market power, that is, the power to charge overly high prices, which is associated with a decrease in social surplus. Although monopolies may be big businesses, size is not a characteristic of a monopoly. A small business may still have the power to raise prices in a small industry (or market).A monopoly may also have monopsony control of a sector of a market. Likewise, a monopoly should be distinguished from a cartel (a form of oligopoly), in which several providers act together to coordinate services, prices or sale of goods. Monopolies, monopsonies and oligopolies are all situations in which one or a few entities have market power and therefore interact with their customers (monopoly or oligopoly), or suppliers (monopsony) in ways that distort the market.Monopolies can be established by a government, form naturally, or form by integration.
