Problem: Armenia:

Other Armenian diasporans that rose to fame in classical or international music circles are world-renowned French-Armenian singer and composer Charles Aznavour, pianist Sahan Arzruni, prominent opera sopranos such as Hasmik Papian and more recently Isabel Bayrakdarian and Anna Kasyan. Certain Armenians settled to sing non-Armenian tunes such as the heavy metal band System of a Down (which nonetheless often incorporates traditional Armenian instrumentals and styling into their songs) or pop star Cher. In the Armenian diaspora, Armenian revolutionary songs are popular with the youth. These songs encourage Armenian patriotism and are generally about Armenian history and national heroes.

Problem: On ancient reliefs, especially from Mesopotamia, kings are often depicted as hunters of big game such as lions and are often portrayed hunting from a war chariot. The cultural and psychological importance of hunting in ancient societies is represented by deities such as the horned god Cernunnos and lunar goddesses of classical antiquity, the Greek Artemis or Roman Diana. Taboos are often related to hunting, and mythological association of prey species with a divinity could be reflected in hunting restrictions such as a reserve surrounding a temple. Euripides' tale of Artemis and Actaeon, for example, may be seen as a caution against disrespect of prey or impudent boasting.
How was the cultural importance of hunting in ancient societies represented?

Context and question: After Christianization, the Roman Catholic Church and local rulers led German expansion and settlement in areas inhabited by Slavs and Balts, known as Ostsiedlung. During the wars waged in the Baltic by the Catholic German Teutonic Knights; the lands inhabited by the ethnic group of the Old Prussians (the current reference to the people known then simply as the "Prussians"), were conquered by the Germans. The Old Prussians were an ethnic group related to the Latvian and Lithuanian Baltic peoples. The former German state of Prussia took its name from the Baltic Prussians, although it was led by Germans who had assimilated the Old Prussians; the old Prussian language was extinct by the 17th or early 18th century. The Slavic people of the Teutonic-controlled Baltic were assimilated into German culture and eventually there were many intermarriages of Slavic and German families, including amongst the Prussia's aristocracy known as the Junkers. Prussian military strategist Karl von Clausewitz is a famous German whose surname is of Slavic origin. Massive German settlement led to the assimilation of Baltic (Old Prussians) and Slavic (Wends) populations, who were exhausted by previous warfare.
When was the Prussian language extinct?
Answer: 17th or early 18th century

Question: Pan-Germanism's origins began in the early 19th century following the Napoleonic Wars. The wars launched a new movement that was born in France itself during the French Revolution. Nationalism during the 19th century threatened the old aristocratic regimes. Many ethnic groups of Central and Eastern Europe had been divided for centuries, ruled over by the old Monarchies of the Romanovs and the Habsburgs. Germans, for the most part, had been a loose and disunited people since the Reformation when the Holy Roman Empire was shattered into a patchwork of states. The new German nationalists, mostly young reformers such as Johann Tillmann of East Prussia, sought to unite all the German-speaking and ethnic-German (Volksdeutsche) people.
Is there an answer to this question: In what century did the Pan-Germanisms origins begin?

Answer: 19th

QUES: Most common glass contains other ingredients to change its properties. Lead glass or flint glass is more 'brilliant' because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eyeglasses.[citation needed] Iron can be incorporated into glass to absorb infrared energy, for example in heat absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs UV wavelengths.

What is another name for lead glass?

flint glass
