Problem: Freemasonry:

In general, Continental Freemasonry is sympathetic to Freemasonry amongst women, dating from the 1890s when French lodges assisted the emergent co-masonic movement by promoting enough of their members to the 33rd degree of the Ancient and Accepted Scottish Rite to allow them, in 1899, to form their own grand council, recognised by the other Continental Grand Councils of that Rite. The United Grand Lodge of England issued a statement in 1999 recognising the two women's grand lodges there to be regular in all but the participants. While they were not, therefore, recognised as regular, they were part of Freemasonry "in general". The attitude of most regular Anglo-American grand lodges remains that women Freemasons are not legitimate Masons.

When did the French try to create co-masonic lodges?

A: the 1890s


Problem: Conventionally, Iranian languages are grouped in "western" and "eastern" branches. These terms have little meaning with respect to Old Avestan as that stage of the language may predate the settling of the Iranian peoples into western and eastern groups. The geographic terms also have little meaning when applied to Younger Avestan since it isn't known where that dialect (or dialects) was spoken either. Certain is only that Avestan (all forms) and Old Persian are distinct, and since Old Persian is "western", and Avestan was not Old Persian, Avestan acquired a default assignment to "eastern". Confusing the issue is the introduction of a western Iranian substrate in later Avestan compositions and redactions undertaken at the centers of imperial power in western Iran (either in the south-west in Persia, or in the north-west in Nisa/Parthia and Ecbatana/Media).
What are the two main divisions of Iranian tongues?

Answer: western and eastern


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
One of the problems of the standard electric light bulb is filament notching due to evaporation of the filament. Small variations in resistivity along the filament cause "hot spots" to form at points of higher resistivity; a variation of diameter of only 1% will cause a 25% reduction in service life. These hot spots evaporate faster than the rest of the filament, which increases the resistance at that point—this creates a positive feedback that ends in the familiar tiny gap in an otherwise healthy-looking filament. Irving Langmuir found that an inert gas, instead of vacuum, would retard evaporation. General service incandescent light bulbs over about 25 watts in rating are now filled with a mixture of mostly argon and some nitrogen, or sometimes krypton. Lamps operated on direct current develop random stairstep irregularities on the filament surface which may cut lifespan in half compared to AC operation; different alloys of tungsten and rhenium can be used to counteract the effect.
Who discovered that inert gas could slow evaporation?
A: Irving Langmuir


Context and question: The Reformation in Europe officially began in 1517 with Martin Luther (1483–1546) and his 95 Theses. The Reformation greatly changed the Baltic region. Its ideas came quickly to the Livonian Confederation and by the 1520s were widespread. Language, education, religion and politics were transformed. Church services were now conducted in the vernacular instead of in Latin, previously used. During the Livonian War in 1561, northern Estonia submitted to Swedish control. In the 1560s two voivodeships of present-day southern Estonia, Dorpat Voivodeship (Tartu region) and Parnawa Voivodeship (Pärnu region), became the autonomous Duchy of Livonia within the Polish-Lithuanian Commonwealth, under joint control of the Polish Crown and the Grand Duchy. In 1629, mainland Estonia came entirely under Swedish rule. Estonia was administratively divided between the provinces of Estonia in the north and Livonia in southern Estonia and northern Latvia. This division persisted until the early twentieth century.
What was the year of Martin Luther's death?
Answer: 1546


Question: German air attacks on the British Isles increased in 1915 and the AA efforts were deemed somewhat ineffective, so a Royal Navy gunnery expert, Admiral Sir Percy Scott, was appointed to make improvements, particularly an integrated AA defence for London. The air defences were expanded with more RNVR AA guns, 75 mm and 3-inch, the pom-poms being ineffective. The naval 3-inch was also adopted by the army, the QF 3 inch 20 cwt (76 mm), a new field mounting was introduced in 1916. Since most attacks were at night, searchlights were soon used, and acoustic methods of detection and locating were developed. By December 1916 there were 183 AA Sections defending Britain (most with the 3-inch), 74 with the BEF in France and 10 in the Middle East.
Is there an answer to this question: How many AA Sections were with the BEF in France during the same time?

Answer: 74


From the 19th century, there was a revival in many ancient glass-making techniques including cameo glass, achieved for the first time since the Roman Empire and initially mostly used for pieces in a neo-classical style. The Art Nouveau movement made great use of glass, with René Lalique, Émile Gallé, and Daum of Nancy producing colored vases and similar pieces, often in cameo glass, and also using luster techniques. Louis Comfort Tiffany in America specialized in stained glass, both secular and religious, and his famous lamps. The early 20th-century saw the large-scale factory production of glass art by firms such as Waterford and Lalique. From about 1960 onwards there have been an increasing number of small studios hand-producing glass artworks, and glass artists began to class themselves as in effect sculptors working in glass, and their works as part fine arts.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did glassworkers begin to consider their products fine art?
Ah, so..
1960
