Input: Read this: Although inefficient, incandescent light bulbs have an advantage in applications where accurate color reproduction is important, since the continuous blackbody spectrum emitted from an incandescent light-bulb filament yields near-perfect color rendition, with a color rendering index of 100 (the best possible). White-balancing is still required to avoid too "warm" or "cool" colors, but this is a simple process that requires only the color temperature in Kelvin as input for modern, digital visual reproduction equipment such as video or still cameras unless it is completely automated. The color-rendering performance of incandescent lights cannot be matched by LEDs or fluorescent lights, although they can offer satisfactory performance for non-critical applications such as home lighting. White-balancing such lights is therefore more complicated, requiring additional adjustments to reduce for example green-magenta color casts, and even when properly white-balanced, the color reproduction will not be perfect.
Question: What can be matched by LEDs or flourescent lights?

Output: unanswerable


QUES: At the time of the fall of the Egyptian monarchy in the early 1950s, less than half a million Egyptians were considered upper class and rich, four million middle class and 17 million lower class and poor. Fewer than half of all primary-school-age children attended school, most of them being boys. Nasser's policies changed this. Land reform and distribution, the dramatic growth in university education, and government support to national industries greatly improved social mobility and flattened the social curve. From academic year 1953-54 through 1965-66, overall public school enrolments more than doubled. Millions of previously poor Egyptians, through education and jobs in the public sector, joined the middle class. Doctors, engineers, teachers, lawyers, journalists, constituted the bulk of the swelling middle class in Egypt under Nasser. During the 1960s, the Egyptian economy went from sluggish to the verge of collapse, the society became less free, and Nasser's appeal waned considerably.

How many middle class were in Egypt in 1950s
What is the answer?
ANS: four million


QUES: Writing to a friend in May 1795, Burke surveyed the causes of discontent: "I think I can hardly overrate the malignity of the principles of Protestant ascendency, as they affect Ireland; or of Indianism [i.e. corporate tyranny, as practiced by the British East Indies Company], as they affect these countries, and as they affect Asia; or of Jacobinism, as they affect all Europe, and the state of human society itself. The last is the greatest evil". By March 1796, however Burke had changed his mind: "Our Government and our Laws are beset by two different Enemies, which are sapping its foundations, Indianism, and Jacobinism. In some Cases they act separately, in some they act in conjunction: But of this I am sure; that the first is the worst by far, and the hardest to deal with; and for this amongst other reasons, that it weakens discredits, and ruins that force, which ought to be employed with the greatest Credit and Energy against the other; and that it furnishes Jacobinism with its strongest arms against all formal Government".
What did Burke think was the worst threat in 1795?

ANS: Jacobinism


John treated the interdict as "the equivalent of a papal declaration of war". He responded by attempting to punish Innocent personally and to drive a wedge between those English clergy that might support him and those allying themselves firmly with the authorities in Rome. John seized the lands of those clergy unwilling to conduct services, as well as those estates linked to Innocent himself; he arrested the illicit concubines that many clerics kept during the period, only releasing them after the payment of fines; he seized the lands of members of the church who had fled England, and he promised protection for those clergy willing to remain loyal to him. In many cases, individual institutions were able to negotiate terms for managing their own properties and keeping the produce of their estates. By 1209 the situation showed no signs of resolution, and Innocent threatened to excommunicate John if he did not acquiesce to Langton's appointment. When this threat failed, Innocent excommunicated the king in November 1209. Although theoretically a significant blow to John's legitimacy, this did not appear to greatly worry the king. Two of John's close allies, Emperor Otto IV and Count Raymond VI of Toulouse, had already suffered the same punishment themselves, and the significance of excommunication had been somewhat devalued. John simply tightened his existing measures and accrued significant sums from the income of vacant sees and abbeys: one 1213 estimate, for example, suggested the church had lost an estimated 100,000 marks (equivalent to £66,666 at the time) to John. Official figures suggest that around 14% of annual income from the English church was being appropriated by John each year.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many marks did the church lose?
Ah, so.. 100,000


Question: Ben Goldacre has argued that regulators – such as the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK, or the Food and Drug Administration (FDA) in the United States – advance the interests of the drug companies rather than the interests of the public due to revolving door exchange of employees between the regulator and the companies and friendships develop between regulator and company employees. He argues that regulators do not require that new drugs offer an improvement over what is already available, or even that they be particularly effective.
Try to answer this question if possible: The FDA argued that which party didn't require that new drugs be improved at all?
Answer: unanswerable


Context and question: Stage lifts and orchestra lifts are specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage. For example, Radio City Music Hall has four such elevators: an orchestra lift that covers a large area of the stage, and three smaller lifts near the rear of the stage. In this case, the orchestra lift is powerful enough to raise an entire orchestra, or an entire cast of performers (including live elephants) up to stage level from below. There's a barrel on the background of the image of the left which can be used as a scale to represent the size of the mechanism
How are stage lifts powered?
Answer:
by hydraulics
