Problem: Please answer a question about the following article about Incandescent light bulb:
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.
How can luminescent light sources be modified to resemble the appearance of incandescents?
A: By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution


Question: Read this and answer the question

From 1940, the Sovereign could appoint a person as a Commander, Officer or Member of the Order of the British Empire for gallantry for acts of bravery (not in the face of the enemy) below the level required for the George Medal. The grade was determined by the same criteria as usual, and not by the level of gallantry (and with more junior people instead receiving the British Empire Medal). Oddly, this meant that it was awarded for lesser acts of gallantry than the George Medal, but, as an Order, was worn before it and listed before it in post-nominal initials. From 14 January 1958, these awards were designated the Order of the British Empire for Gallantry.

Of what acts did the Members of the Order of the British Empire appoint?
Answer: below the level required for the George Medal


Problem: Not all of the Luftwaffe's effort was made against inland cities. Port cities were also attacked to try to disrupt trade and sea communications. In January Swansea was bombed four times, very heavily. On 17 January around 100 bombers dropped a high concentration of incendiaries, some 32,000 in all. The main damage was inflicted on the commercial and domestic areas. Four days later 230 tons was dropped including 60,000 incendiaries. In Portsmouth Southsea and Gosport waves of 150 bombers destroyed vast swaths of the city with 40,000 incendiaries. Warehouses, rail lines and houses were destroyed and damaged, but the docks were largely untouched.
What was primarily damaged in the attacks?
The answer is the following: commercial and domestic areas


Shooting as practised in Britain, as opposed to traditional hunting, requires little questing for game—around thirty-five million birds are released onto shooting estates every year, some having been factory farmed. Shoots can be elaborate affairs with guns placed in assigned positions and assistants to help load shotguns. When in position, "beaters" move through the areas of cover, swinging sticks or flags to drive the game out. Such events are often called "drives". The open season for grouse in the UK begins on 12 August, the so-called Glorious Twelfth. The definition of game in the United Kingdom is governed by the Game Act 1831.
Who uses swinging sticks or flags to drive game out?
"beaters"


Input: Jews
Genetic studies on Jews show that most Jews worldwide bear a common genetic heritage which originates in the Middle East, and that they bear their strongest resemblance to the peoples of the Fertile Crescent. The genetic composition of different Jewish groups shows that Jews share a common genetic pool dating back 4,000 years, as a marker of their common ancestral origin. Despite their long-term separation and beside their shared genetic origin, Jews also maintained a common culture, tradition, and language.

Genetic studies show that Jews bear their strongest resemblance to the peoples of where?
Output: Fertile Crescent


Problem: Please answer a question about the following article about Frédéric Chopin:
In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (£1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.
In addition to hearing him play, what else did people seek from Chopin in London?
A:
piano lessons
