Article: In the Southern Netherlands (now Belgium and Luxembourg) developments were different. Under Spanish, then Austrian, and then French rule standardisation of Dutch language came to a standstill. The state, law, and increasingly education used French, yet more than half the Belgian population were speaking a Dutch dialect. In the course of the nineteenth century the Flemish movement stood up for the rights of Dutch, mostly called Flemish. But in competing with the French language the variation in dialects was a serious disadvantage. Since standardisation is a lengthy process, Dutch-speaking Belgium associated itself with the standard language that had already developed in the Netherlands over the centuries. Therefore, the situation in Belgium is essentially no different from that in the Netherlands, although there are recognisable differences in pronunciation, comparable to the pronunciation differences between standard British and standard American English. In 1980 the Netherlands and Belgium concluded the Language Union Treaty. This treaty lays down the principle that the two countries must gear their language policy to each other, among other things, for a common system of spelling.

Question: What was the old name for the geographical region that's now Belgium and Luxembourg?
Ans: Southern Netherlands

Article: Much of the country lies between the Tropic of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.9 in) of rain annually. Annual rainfall in the delta region is approximately 2,500 mm (98.4 in), while average annual rainfall in the Dry Zone in central Myanmar is less than 1,000 mm (39.4 in). The Northern regions of Myanmar are the coolest, with average temperatures of 21 C (70 F). Coastal and delta regions have an average maximum temperature of 32 C (89.6 F).

Question: Where does the majority of the Burmese country fall on the globe ?
Ans: Much of the country lies between the Tropic of Cancer and the Equator

Article: Luminous efficacy of a light source may be defined in two ways. The radiant luminous efficacy (LER) is the ratio of the visible light flux emitted (the luminous flux) to the total power radiated over all wavelengths. The source luminous efficacy (LES) is the ratio of the visible light flux emitted (the luminous flux) to the total power input to the source, such as a lamp. Visible light is measured in lumens, a unit which is defined in part by the differing sensitivity of the human eye to different wavelengths of light. Not all wavelengths of visible electromagnetic energy are equally effective at stimulating the human eye; the luminous efficacy of radiant energy (LER) is a measure of how well the distribution of energy matches the perception of the eye. The units of luminous efficacy are "lumens per watt" (lpw). The maximum LER possible is 683 lm/W for monochromatic green light at 555 nanometers wavelength, the peak sensitivity of the human eye.

Question: What is the definition of radiant luminous efficacy?
Ans: the ratio of the visible light flux emitted (the luminous flux) to the total power radiated over all wavelengths

Article: Aside from the official forms of their respective languages, the four linguistic regions of Switzerland also have their local dialectal forms. The role played by dialects in each linguistic region varies dramatically: in the German-speaking regions, Swiss German dialects have become ever more prevalent since the second half of the 20th century, especially in the media, such as radio and television, and are used as an everyday language, while the Swiss variety of Standard German is almost always used instead of dialect for written communication (c.f. diglossic usage of a language). Conversely, in the French-speaking regions the local dialects have almost disappeared (only 6.3% of the population of Valais, 3.9% of Fribourg, and 3.1% of Jura still spoke dialects at the end of the 20th century), while in the Italian-speaking regions dialects are mostly limited to family settings and casual conversation.

Question: What has happened to the local dialects in the French speaking regions?
Ans:
have almost disappeared
