With nitrides containing aluminium, most often AlGaN and AlGaInN, even shorter wavelengths are achievable. Ultraviolet LEDs in a range of wavelengths are becoming available on the market. Near-UV emitters at wavelengths around 375395 nm are already cheap and often encountered, for example, as black light lamp replacements for inspection of anti-counterfeiting UV watermarks in some documents and paper currencies. Shorter-wavelength diodes, while substantially more expensive, are commercially available for wavelengths down to 240 nm. As the photosensitivity of microorganisms approximately matches the absorption spectrum of DNA, with a peak at about 260 nm, UV LED emitting at 250270 nm are to be expected in prospective disinfection and sterilization devices. Recent research has shown that commercially available UVA LEDs (365 nm) are already effective disinfection and sterilization devices. UV-C wavelengths were obtained in laboratories using aluminium nitride (210 nm), boron nitride (215 nm) and diamond (235 nm).
Shorter wavelength diodes provide wavelengths as low as what?
240 nm

Input: Predation
An alternative view offered by Richard Dawkins is of predation as a form of competition: the genes of both the predator and prey are competing for the body (or 'survival machine') of the prey organism. This is best understood in the context of the gene centered view of evolution. Another manner in which predation and competition are connected is throughout intraguild predation. Intraguild predators are those that kill and eat other predators of different species at the same trophic level, and thus that are potential competitors.

To what part of the prey does Richard Dawkins refer to as the "survival machine"?
Output: the body

Input: Article: Iran has an area of 1,648,195 km2 (636,372 sq mi). Iran lies between latitudes 24 and 40 N, and longitudes 44 and 64 E. Its borders are with Azerbaijan (611 km or 380 mi, with Azerbaijan-Naxcivan exclave, 179 km or 111 mi) and Armenia (35 km or 22 mi) to the north-west; the Caspian Sea to the north; Turkmenistan (992 km or 616 mi) to the north-east; Pakistan (909 km or 565 mi) and Afghanistan (936 km or 582 mi) to the east; Turkey (499 km or 310 mi) and Iraq (1,458 km or 906 mi) to the west; and finally the waters of the Persian Gulf and the Gulf of Oman to the south.

Now answer this question: What longitudes does Iran lie between?

Output: 44 and 64 E

Article: On 10 February 2010, the 122nd IOC session at Vancouver announced Nanjing as the host city for the 2nd Summer Youth Olympic Games. The slogan of the 2014 Youth Olympic Games was "Share the Games, Share our Dreams". The Nanjing 2014 Youth Olympic Games featured all 28 sports on the Olympic programme and were held from 16 to 28 August. The Nanjing Youth Olympic Games Organising Committee (NYOGOC) worked together with the International Olympic Committee (IOC) to attract the best young athletes from around the world to compete at the highest level. Off the competition fields, an integrated culture and education programme focused on discussions about education, Olympic values, social challenges, and cultural diversity. The YOG aims to spread the Olympic spirit and encourage sports participation.

Question: How many types of sports were performed in the 2014 Youth Olympic Games?
Ans: 28

Here is a question about this article: At the outset of the Franco-Prussian War, 462,000 German soldiers concentrated on the French frontier while only 270,000 French soldiers could be moved to face them, the French army having lost 100,000 stragglers before a shot was fired through poor planning and administration. This was partly due to the peacetime organisations of the armies. Each Prussian Corps was based within a Kreis (literally "circle") around the chief city in an area. Reservists rarely lived more than a day's travel from their regiment's depot. By contrast, French regiments generally served far from their depots, which in turn were not in the areas of France from which their soldiers were drawn. Reservists often faced several days' journey to report to their depots, and then another long journey to join their regiments. Large numbers of reservists choked railway stations, vainly seeking rations and orders.
What is the answer to this question: How many French troops were available to stand again the Germans?
****
So... 270,000

Article: The accession of Valens gave a fresh lease of life to the Arian party. He issued a decree banishing the bishops who had been deposed by Constantius, but who had been permitted by Jovian to return to their sees. The news created the greatest consternation in the city of Alexandria itself, and the prefect, in order to prevent a serious outbreak, gave public assurance that the very special case of Athanasius would be laid before the emperor. But the saint seems to have divined what was preparing in secret against him. He quietly withdrew from Alexandria, 5 October, and took up his abode in a country house outside the city. Valens, who seems to have sincerely dreaded the possible consequences of another popular outbreak, within a few weeks issued orders allowing Athanasius to return to his episcopal see.

Question: Valens' banishment of Athanasius created the greatest consternation in what city?
Ans:
Alexandria
