Input: Read this: There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights. These devices produce light by luminescence. These lamps produce discrete spectral lines and do not have the broad "tail" of invisible infrared emissions. By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution, the spectrum emitted can be tuned to mimic the appearance of incandescent sources, or other different color temperatures of white light. Due to the discrete spectral lines rather than a continuous spectrum, the light is not ideal for applications such as photography and cinematography.
Question: How can luminescent light sources be modified to resemble the appearance of incandescents?

Output: By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution


QUES: Humbert of Romans, the master general of the order from 1254 to 1263, was a great administrator, as well as preacher and writer. It was under his tenure as master general that the sisters in the order were given official membership. Humbert was a great lover of languages, and encouraged linguistic studies among the Dominicans, primarily Arabic, because of the missionary work friars were pursuing amongst those led astray or forced to convert by Muslims in the Middle East. He also wanted his friars to reach excellence in their preaching, and this was his most lasting contribution to the order. The growth of the spirituality of young preachers was his first priority. He once cried to his students: "... consider how excellent this office [of preaching] is, because it is apostolic; how useful, because it is directly ordained for the salvation of souls; how perilous, because few have in them, or perform, what the office requires, for it is not without great danger ... , vol. xxv. (Lyon, 1677)

What did Hobart not want the friars to reach?

QUES: The centre of Argentoratum proper was situated on the Grande Île (Cardo: current Rue du Dôme, Decumanus: current Rue des Hallebardes). The outline of the Roman "castrum" is visible in the street pattern in the Grande Ile. Many Roman artifacts have also been found along the current Route des Romains, the road that led to Argentoratum, in the suburb of Kœnigshoffen. This was where the largest burial places were situated, as well as the densest concentration of civilian dwelling places and commerces next to the camp. Among the most outstanding finds in Kœnigshoffen were (found in 1911–12) the fragments of a grand Mithraeum that had been shattered by early Christians in the fourth century. From the fourth century, Strasbourg was the seat of the Bishopric of Strasbourg (made an Archbishopric in 1988). Archaeological excavations below the current Église Saint-Étienne in 1948 and 1956 unearthed the apse of a church dating back to the late fourth or early fifth century, considered to be the oldest church in Alsace. It is supposed that this was the first seat of the Roman Catholic Diocese of Strasbourg.
In what year was the Route des Romains established?

ANS: unanswerable


"Digimon" are "Digital Monsters". According to the stories, they are inhabitants of the "DigiWorld", a manifestation of Earth's communication network. The stories tell of a group of mostly pre-teens, who accompany special Digimon born to defend their world (and ours) from various evil forces. To help them surmount the most difficult obstacles found within both realms, the Digimon have the ability to evolve (Digivolve) In this process, the Digimon change appearance and become much stronger, often changing in personality as well. The group of children who come in contact with the Digital World changes from series to series.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who accompanies special humans born to save the world?
Ah, so.. unanswerable


Question: If a tree grows all its life in the open and the conditions of soil and site remain unchanged, it will make its most rapid growth in youth, and gradually decline. The annual rings of growth are for many years quite wide, but later they become narrower and narrower. Since each succeeding ring is laid down on the outside of the wood previously formed, it follows that unless a tree materially increases its production of wood from year to year, the rings must necessarily become thinner as the trunk gets wider. As a tree reaches maturity its crown becomes more open and the annual wood production is lessened, thereby reducing still more the width of the growth rings. In the case of forest-grown trees so much depends upon the competition of the trees in their struggle for light and nourishment that periods of rapid and slow growth may alternate. Some trees, such as southern oaks, maintain the same width of ring for hundreds of years. Upon the whole, however, as a tree gets larger in diameter the width of the growth rings decreases.
Try to answer this question if possible: As a tree ages, do its growth rings usually get wider or narrower?
Answer: narrower


QUES:  The strength of beers has climbed during the later years of the 20th century. Vetter 33, a 10.5% abv (33 degrees Plato, hence Vetter "33") doppelbock, was listed in the 1994 Guinness Book of World Records as the strongest beer at that time, though Samichlaus, by the Swiss brewer Hürlimann, had also been listed by the Guinness Book of World Records as the strongest at 14% abv. Since then, some brewers have used champagne yeasts to increase the alcohol content of their beers. Samuel Adams reached 20% abv with Millennium, and then surpassed that amount to 25.6% abv with Utopias. The strongest beer brewed in Britain was Baz's Super Brew by Parish Brewery, a 23% abv beer. In September 2011, the Scottish brewery BrewDog produced Ghost Deer, which, at 28%, they claim to be the world's strongest beer produced by fermentation alone.
What do brewing companies sometimes use to give more alcohol content to their beer?

ANS:
champagne yeasts
