Problem: Text: The German Shepherd (German: Deutscher Schaferhund, German pronunciation: (fhnt)) is a breed of medium to large-sized working dog that originated in Germany. The breed's officially recognized name is German Shepherd Dog in the English language (sometimes abbreviated as GSD). The breed is known as the Alsatian in Britain and Ireland. The German Shepherd is a relatively new breed of dog, with their origin dating to 1899. As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep. Since that time however, because of their strength, intelligence, trainability, and obedience, German Shepherds around the world are often the preferred breed for many types of work, including disability assistance, search-and-rescue, police and military roles, and even acting. The German Shepherd is the second-most registered breed by the American Kennel Club and seventh-most registered breed by The Kennel Club in the United Kingdom.

Problem: Text: Many languages are spoken, or historically have been spoken, in the United States. Today over 500 languages are used by the U.S. population. The most commonly used language is English (specifically, American English), which is the de facto national language of the United States. Since the 1965 Immigration Act, Spanish is the second most common language in the country. The United States does not have an official language, but some state governments recognize specific languages. For instance, the state government of Louisiana offers services and documents in French, as does New Mexico in Spanish. There are many languages indigenous to North America or to U.S. states or holdings in the Pacific region. Hawaiian, although having few native speakers, is an official language along with English of the state of Hawaii. Alaska officializes English and twenty native languages.

Problem: Text: In 1758, Carl Linnaeus created the first hierarchical classification in his Systema Naturae. In his original scheme, the animals were one of three kingdoms, divided into the classes of Vermes, Insecta, Pisces, Amphibia, Aves, and Mammalia. Since then the last four have all been subsumed into a single phylum, the Chordata, while his Insecta (which included the crustaceans and arachnids) and Vermes have been renamed or broken up. The process was begun in 1793 by Jean-Baptiste de Lamarck, who called the Vermes une espece de chaos (a sort of chaos) and split the group into three new phyla, worms, echinoderms, and polyps (which contained corals and jellyfish). By 1809, in his Philosophie Zoologique, Lamarck had created 9 phyla apart from vertebrates (where he still had 4 phyla: mammals, birds, reptiles, and fish) and molluscs, namely cirripedes, annelids, crustaceans, arachnids, insects, worms, radiates, polyps, and infusorians.
