The giraffe (Giraffa) is an African artiodactyl mammal, the tallest living terrestrial animal and the largest ruminant.  It is traditionally considered to be one species, Giraffa camelopardalis, with nine subspecies. However, the existence of up to nine extant giraffe species has been described, based upon research into the mitochondrial and nuclear DNA, as well as morphological measurements of Giraffa. Seven other species are extinct, prehistoric species known from fossils.
The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs and woodlands. Their food source is leaves, fruits and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach.
Giraffes may be preyed on by lions, leopards, spotted hyenas and African wild dogs.

Smoking is a practice in which a substance is burned and the resulting smoke is breathed in to be tasted and absorbed into the bloodstream.  Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a "cigarette".  Smoking is primarily practised as a route of administration for recreational drug use because the combustion of the dried plant leaves vaporizes and delivers active substances into the lungs where they are rapidly absorbed into the bloodstream and reach bodily tissue.  In the case of cigarette smoking these substances are contained in a mixture of aerosol particles and gases and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas into a form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs.  In some cultures, smoking is also carried out as a part of various rituals, where participants use it to help induce trance-like states that, they believe, can lead them to spiritual enlightenment.
Smoking is one of the most common forms of recreational drug use. Tobacco smoking is the most popular form, being practised by over one billion people globally, of whom the majority are in the developing countries. Less common drugs for smoking include cannabis and opium. Some of the substances are classified as hard narcotics, like heroin, but the use of these is very limited as they are usually not commercially available. Cigarettes are primarily industrially manufactured but also can be hand-rolled from loose tobacco and rolling paper.

The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. A boar (adult male) weighs around 350–700 kg (770–1,540 lb), while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect. For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures.

The koala or, inaccurately, koala bear  (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats, which are members of the family Vombatidae. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
Koalas typically inhabit open eucalypt woodlands, and the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to 20 hours a day.

Vikings is the modern name given to seafaring Norse pirates from southern Scandinavia (present-day Denmark, Norway and Sweden) who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.  They also voyaged as far as the Mediterranean, North Africa, the Middle East, and North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term 'Viking' also commonly includes the inhabitants of the Norse homelands as a collective whole. The Vikings had a profound impact on the  Early medieval history of Scandinavia, the British Isles, France, Estonia, and Kievan Rus'.Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlements and governments in the British Isles, Ireland, the Faroe Islands, Iceland, Greenland, Normandy, the Baltic coast, and along the Dnieper and Volga trade routes in what is now European Russia, Belarus and Ukraine (where they were also known as Varangians). The Normans, Norse-Gaels, Rus' people, Faroese and Icelanders emerged from these Norse colonies. The Vikings also voyaged to Constantinople, Iran, and Arabia. They were the first Europeans to reach North America, briefly settling in Newfoundland (Vinland). While spreading Norse culture to foreign lands, they simultaneously brought home slaves, concubines and foreign cultural influences to Scandinavia, profoundly influencing the genetic and historical development of both. During the Viking Age the Norse homelands were gradually consolidated from smaller kingdoms into three larger kingdoms: Denmark, Norway and Sweden.The Vikings spoke Old Norse and made inscriptions in runes. For most of the period they followed the Old Norse religion, but later became Christians.

A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural women is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. 
Typically, women have two X chromosomes and are capable of pregnancy and giving birth from puberty until menopause. Female anatomy, as distinguished from male anatomy, includes the fallopian tubes, ovaries, uterus, vulva, Skene's glands, and Bartholin's glands. The adult female pelvis is wider, the hips broader, and the breasts larger than that of adult males. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men.
Throughout human history, traditional gender roles have often defined and limited women's activities and opportunities; many religious doctrines stipulate certain rules for women. With restrictions loosening during the 20th century in many societies, women have gained access to careers beyond the traditional homemaker, and the ability to pursue higher education. Violence against women, whether within families or in communities, has a long history and is primarily committed by men.

A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths and spacings of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called matrix codes or 2D barcodes, although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode reader using specialized application software. (The same sort of mobile device could also read 1D barcodes, depending on the application software.)
The barcode was invented by Norman Joseph Woodland and Bernard Silver and patented in the US in 1951. The invention was based on Morse code that was extended to thin and thick bars. However, it took over twenty years before this invention became commercially successful.

Poetry (derived from the Greek poiesis, "making") is a form of literature that uses aesthetic and often rhythmic qualities of language—such as phonaesthetics, sound symbolism, and metre—to evoke meanings in addition to, or in place of, the prosaic ostensible meaning.
Poetry has a long and varied history, evolving differentially across the globe.  It dates back at least to prehistoric times with hunting poetry in Africa, and to panegyric and elegiac court poetry of the empires of the Nile, Niger, and Volta River valleys. Some of the earliest written poetry in Africa occurs among the Pyramid Texts written during the 25th century BCE. The earliest surviving Western Asian epic poetry, the Epic of Gilgamesh, was written in Sumerian.
Early poems in the Eurasian continent evolved from folk songs such as the Chinese Shijing; or from a need to retell oral epics, as with the Sanskrit Vedas, the Zoroastrian Gathas, and the Homeric epics, the Iliad and the Odyssey. Ancient Greek attempts to define poetry, such as Aristotle's Poetics, focused on the uses of speech in rhetoric, drama, song, and comedy. Later attempts concentrated on features such as repetition, verse form, and rhyme, and emphasized the aesthetics which distinguish poetry from more objectively-informative prosaic writing.
Poetry uses forms and conventions to suggest differential interpretations of words, or to evoke emotive responses. Devices such as assonance, alliteration, onomatopoeia, and rhythm may convey musical or incantatory effects. The use of ambiguity, symbolism, irony, and other stylistic elements of poetic diction often leaves a poem open to multiple interpretations.

Albert Einstein ( EYEN-styne; German: [ˈalbɛʁt ˈʔaɪnʃtaɪn] (listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest physicists of all time. Einstein is known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics. His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius".In 1905, a year sometimes described as his annus mirabilis ('miracle year'), Einstein published four groundbreaking papers. These outlined the theory of the photoelectric effect, explained Brownian motion, introduced special relativity, and demonstrated mass-energy equivalence. Einstein thought that the laws of classical mechanics could no longer be reconciled with those of the electromagnetic field, which led him to develop his special theory of relativity. He then extended the theory to gravitational fields; he published a paper on general relativity in 1916, introducing his theory of gravitation.

A raven is one of several larger-bodied species of the genus Corvus. These species do not form a single taxonomic group within the genus.
There is no consistent distinction between "crows" and "ravens", and these appellations have been assigned to different species chiefly on the basis of their size, crows generally being smaller than ravens.
The largest raven species are the common raven and the thick-billed raven.


== Etymology ==
The term "raven" originally referred to the common raven (Corvus corax), the type species of the genus Corvus, which has a larger distribution than any other species of Corvus, ranging over much of the Northern Hemisphere.
The modern English word raven has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) hrafn and Old High German (h)raban, all of which descend from Proto-Germanic *hrabanaz.Collective nouns for a group of ravens (or at least the common raven) include "rave", "treachery", "unkindness" and "conspiracy". In practice, most people use the more generic "flock".

The wedding of Prince Charles and Lady Diana Spencer took place on Wednesday 29 July 1981 at St Paul's Cathedral in London, United Kingdom. The groom was the heir apparent to the British throne, and the bride was a member of the Spencer family.
The ceremony was a traditional Church of England wedding service. The dean of St Paul's Cathedral, Alan Webster, presided at the service, and the archbishop of Canterbury, Robert Runcie, conducted the marriage. Notable figures in attendance included many members of other royal families, republican heads of state, and members of the bride's and groom's families. After the ceremony, the couple made the traditional appearance on the balcony of Buckingham Palace. The United Kingdom had a national holiday on that day to mark the wedding. The ceremony featured many ceremonial aspects, including use of the state carriages and roles for the Foot Guards and Household Cavalry.
Their marriage was widely billed as a "fairytale wedding" and the "wedding of the century". It was watched by an estimated global TV audience of 750 million people.

Columbidae () is a bird family consisting of pigeons and doves. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms.
The family contains 344 species divided into 50 genera. Thirteen of the species are extinct.In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon.
