The problem: Answer a question about this article:
German beacons operated on the medium-frequency band and the signals involved a two-letter Morse identifier followed by a lengthy time-lapse which enabled the Luftwaffe crews to determine the signal's bearing. The Meacon system involved separate locations for a receiver with a directional aerial and a transmitter. The receipt of the German signal by the receiver was duly passed to the transmitter, the signal to be repeated. The action did not guarantee automatic success. If the German bomber flew closer to its own beam than the Meacon then the former signal would come through the stronger on the direction finder. The reverse would apply only if the meacon were closer.
The German beacons used what frequency band?
****
The answer: medium

Carpet-weaving is historically a major traditional profession for the majority of Armenian women, including many Armenian families. Prominent Karabakh carpet weavers there were men too. The oldest extant Armenian carpet from the region, referred to as Artsakh (see also Karabakh carpet) during the medieval era, is from the village of Banants (near Gandzak) and dates to the early 13th century. The first time that the Armenian word for carpet, gorg, was used in historical sources was in a 1242–1243 Armenian inscription on the wall of the Kaptavan Church in Artsakh.
Where is the earliest known use of 'gorg'?
****
The answer: in a 1242–1243 Armenian inscription on the wall of the Kaptavan Church in Artsakh


The problem: Answer a question about this article:
Due to great differences in terrain, the climate of the province is highly variable. In general it has strong monsoonal influences, with rainfall heavily concentrated in the summer. Under the Köppen climate classification, the Sichuan Basin (including Chengdu) in the eastern half of the province experiences a humid subtropical climate (Köppen Cwa or Cfa), with long, hot, humid summers and short, mild to cool, dry and cloudy winters. Consequently, it has China's lowest sunshine totals. The western region has mountainous areas producing a cooler but sunnier climate. Having cool to very cold winters and mild summers, temperatures generally decrease with greater elevation. However, due to high altitude and its inland location, many areas such as Garze County and Zoige County in Sichuan exhibit a subarctic climate (Köppen Dwc)- featuring extremely cold winters down to -30 °C and even cold summer nights. The region is geologically active with landslides and earthquakes. Average elevation ranges from 2,000 to 3,500 meters; average temperatures range from 0 to 15 °C. The southern part of the province, including Panzhihua and Xichang, has a sunny climate with short, very mild winters and very warm to hot summers.
What climate classification does the Sichuan Basin hold?
****
The answer: humid subtropical climate


The problem: Answer a question about this article:
By the end of 2011, total renewable power capacity worldwide exceeded 1,360 GW, up 8%. Renewables producing electricity accounted for almost half of the 208 GW of capacity added globally during 2011. Wind and solar photovoltaics (PV) accounted for almost 40% and 30% . Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% electricity from wind, solar, geothermal, and biomass.
Renewables contributed what percentage to our electricity generation?
****
The answer:
22 percent
