The Czechs' language separated from other Slavic tongues into what would later be called Old Czech by the thirteenth century, a classification extending through the sixteenth century. Its use of cases differed from the modern language; although Old Czech did not yet have a vocative case or an animacy distinction, declension for its six cases and three genders rapidly became complicated (partially to differentiate homophones) and its declension patterns resembled those of Lithuanian (its Balto-Slavic cousin).
What other language did Old Czech's declension patterns resemble?
****
The answer: Lithuanian

Valerian's first religious edict singled out Christianity as a particularly self-interested and subversive foreign cult, outlawed its assemblies and urged Christians to sacrifice to Rome's traditional gods. His second edict acknowledged a Christian threat to the Imperial system not yet at its heart but close to it, among Rome's equites and Senators. Christian apologists interpreted his disgraceful capture and death as divine judgement. The next forty years were peaceful; the Christian church grew stronger and its literature and theology gained a higher social and intellectual profile, due in part to its own search for political toleration and theological coherence. Origen discussed theological issues with traditionalist elites in a common Neoplatonist frame of reference he had written to Decius' predecessor Philip the Arab in similar vein and Hippolytus recognised a "pagan" basis in Christian heresies. The Christian churches were disunited; Paul of Samosata, Bishop of Antioch was deposed by a synod of 268 for "dogmatic reasons his doctrine on the human nature of Christ was rejected and for his lifestyle, which reminded his brethren of the habits of the administrative elite". The reasons for his deposition were widely circulated among the churches. Meanwhile, Aurelian (270-75) appealed for harmony among his soldiers (concordia militum), stabilised the Empire and its borders and successfully established an official, Hellenic form of unitary cult to the Palmyrene Sol Invictus in Rome's Campus Martius.
To what gods did Valerian tell the Christians to sacrifice?
****
The answer: Rome's traditional

In 1931, RCA Victor introduced their vinyl-based Victrolac compound as a material for some unusual-format and special-purpose records. By the end of the 1930s vinyl's advantages of light weight, relative unbreakability and low surface noise had made it the material of choice for prerecorded radio programming and other critical applications. When it came to ordinary 78 rpm records, however, the much higher cost of the raw material, as well as its vulnerability to the heavy pickups and crudely mass-produced steel needles still commonly used in home record players, made its general substitution for shellac impractical at that time. During the Second World War, the United States Armed Forces produced thousands of 12-inch vinyl 78 rpm V-Discs for use by the troops overseas. After the war, the wider use of vinyl became more practical as new record players with relatively lightweight crystal pickups and precision-ground styli made of sapphire or an exotic osmium alloy proliferated. In late 1945, RCA Victor began offering special transparent red vinyl De Luxe pressings of some classical 78s, at a de luxe price. Later, Decca Records introduced vinyl Deccalite 78s, while other record companies came up with vinyl concoctions such as Metrolite, Merco Plastic and Sav-o-flex, but these were mainly used to produce "unbreakable" children's records and special thin vinyl DJ pressings for shipment to radio stations.
What was Metrolite and Sav-o-flex materials primarily used for?
****
The answer: children's records

The problem: Answer a question about this article:
Paris' urbanism laws have been under strict control since the early 17th century, particularly where street-front alignment, building height and building distribution is concerned. In recent developments, a 1974-2010 building height limitation of 37 metres (121 ft) was raised to 50 m (160 ft) in central areas and 180 metres (590 ft) in some of Paris' peripheral quarters, yet for some of the city's more central quarters, even older building-height laws still remain in effect. The 210 metres (690 ft) Montparnasse tower was both Paris and France's tallest building until 1973, but this record has been held by the La Defense quarter Tour First tower in Courbevoie since its 2011 construction. A new project for La Defense, called Hermitage Plaza, launched in 2009, proposes to build two towers, 85 and 86 stories or 320 metres high, which would be the tallest buildings in the European Union, just slightly shorter than the Eiffel Tower. They were scheduled for completion in 2019 or 2020, but as of January 2015 construction had not yet begun, and there were questions in the press about the future of the project.
What is the name of the project for La Defense called that has not yet been started?
****
The answer:
Hermitage Plaza
