Q: Information:  - Crayfish, also known as crawfish, crawdads, freshwater lobsters, mountain lobsters, mudbugs or yabbies, are freshwater crustaceans resembling small lobsters, to which they are related; taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams where there is running fresh water, while others thrive in swamps, ditches, and rice paddies. Most crayfish cannot tolerate polluted water, although some species such as "Procambarus clarkii" are hardier. Crayfish feed on living and dead animals and plants.  - Procambarus clarkii is a freshwater crayfish species, native to the Southeastern United States, but found also on other continents, where it is often an invasive pest. It is known variously as the red swamp crawfish, red swamp crayfish, Louisiana crawfish, Louisiana crayfish or mudbug.  - Louisiana (or  ; Louisiana Creole: "Léta de la Lwizyàn") is a state located in the southern region of the United States. Louisiana is the 31st most extensive and the 25th most populous of the 50 United States. Its capital is Baton Rouge and largest city is New Orleans. Louisiana is the only state in the U.S. with political subdivisions termed parishes, which are the local government's equivalent to counties. The largest parish by population is East Baton Rouge Parish, and the largest by total area is Plaquemines. Louisiana is bordered by Arkansas to the north, Mississippi to the east, Texas to the west, and the Gulf of Mexico to the south.  - Lobsters comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans.  - Cambaroides is a genus of freshwater crayfish from eastern Asia (eastern Russia, northeastern China, Korean Peninsula and Japan). Together with "Astacus", they are the only crayfish native to Asia. "Cambaroides" contains seven species:  - Cambaridae is the largest of the three families of freshwater crayfish , with over 400 species . Most of the species in the family are native to North America east of the Great Divide , such as the invasive species Procambarus clarkii and Orconectes rusticus , with fewer species living in East Asia and Japan , such as zarigani ( Cambaroides japonicus ) . A 2006 molecular study suggested that the family Cambaridae may be paraphyletic , with the family Astacidae nested within it , and the status of the genus Cambaroides remains unclear .  - Astacus (from the Greek , "", meaning "lobster" or "crayfish") is a genus of crayfish found in Europe and western Asia, comprising three extant and four extinct species.  - A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment.    What is the relationship between 'cambaridae' and 'astacoidea'?

Q: Information:  - The Triple Entente (from French "entente" "friendship, understanding, agreement") was the understanding linking the Russian Empire, the French Third Republic, and the United Kingdom of Great Britain and Ireland after the signing of the Anglo-Russian Entente on 31 August 1907. The understanding between the three powers, supplemented by agreements with Japan and Portugal, constituted a powerful counterweight to the Triple Alliance of Germany, Austria-Hungary and the Kingdom of Italy, though Italy did not side with Germany and Austria during World War I, and joined the Entente Powers instead, in the 1915 Treaty of London.  - The Second Battle of the Masurian Lakes , also known as the Winter Battle of the Masurian Lakes , was the northern part of the Central Powers ' offensive on the Eastern Front in the winter of 1915 . The offensive was intended to advance beyond the Vistula River and perhaps knock Russia out of the war .  - The Ottoman Empire ('; Modern Turkish: ' or '), also known as the Turkish Empire, Ottoman Turkey, was an empire founded at the end of the thirteenth century in northwestern Anatolia in the vicinity of Bilecik and Söüt by the Oghuz Turkish tribal leader Osman. After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror.  - The Central Powers , consisting of Germany, , the Ottoman Empire and Bulgaria  hence also known as the Quadruple Alliance  was one of the two main factions during World War I (191418). It faced and was defeated by the Allied Powers that had formed around the Triple Entente, after which it was dissolved.    What is the relationship between 'second battle of the masurian lakes' and 'world war i'?
