Problem: Pharmaceutical industry:

Drug discovery and development is very expensive; of all compounds investigated for use in humans only a small fraction are eventually approved in most nations by government appointed medical institutions or boards, who have to approve new drugs before they can be marketed in those countries. In 2010 18 NMEs (New Molecular Entities) were approved and three biologics by the FDA, or 21 in total, which is down from 26 in 2009 and 24 in 2008. On the other hand, there were only 18 approvals in total in 2007 and 22 back in 2006. Since 2001, the Center for Drug Evaluation and Research has averaged 22.9 approvals a year. This approval comes only after heavy investment in pre-clinical development and clinical trials, as well as a commitment to ongoing safety monitoring. Drugs which fail part-way through this process often incur large costs, while generating no revenue in return. If the cost of these failed drugs is taken into account, the cost of developing a successful new drug (new chemical entity, or NCE), has been estimated at about 1.3 billion USD(not including marketing expenses). Professors Light and Lexchin reported in 2012, however, that the rate of approval for new drugs has been a relatively stable average rate of 15 to 25 for decades.

How many drugs were approved in 2007?

A: 18 approvals

Problem: The economy of Russia became heavily industrialized, accounting for about two-thirds of the electricity produced in the USSR. It was, by 1961, the third largest producer of petroleum due to new discoveries in the Volga-Urals region and Siberia, trailing only the United States and Saudi Arabia. In 1974, there were 475 institutes of higher education in the republic providing education in 47 languages to some 23,941,000 students. A network of territorially-organized public-health services provided health care. After 1985, the restructuring policies of the Gorbachev administration relatively liberalised the economy, which had become stagnant since the late 1970s, with the introduction of non-state owned enterprises such as cooperatives. The effects of market policies led to the failure of many enterprises and total instability by 1990.
How much of the USSR's electricity was delayed in the RSFSR?

Context and question: British imperial strength was underpinned by the steamship and the telegraph, new technologies invented in the second half of the 19th century, allowing it to control and defend the Empire. By 1902, the British Empire was linked together by a network of telegraph cables, the so-called All Red Line. Growing until 1922, around 13,000,000 square miles (34,000,000 km2) of territory and roughly 458 million people were added to the British Empire. The British established colonies in Australia in 1788, New Zealand in 1840 and Fiji in 1872, with much of Oceania becoming part of the British Empire.
What was British imperial strength replace by?
Answer: steamship and the telegraph

Question: The back of the cartridge bears a label with instructions on handling. Production and software revision codes were imprinted as stamps on the back label to correspond with the software version and producer. With the exception of The Legend of Zelda and Zelda II: The Adventure of Link, manufactured in gold-plastic carts, all licensed NTSC and PAL cartridges are a standard shade of gray plastic. Unlicensed carts were produced in black, robin egg blue, and gold, and are all slightly different shapes than standard NES cartridges. Nintendo also produced yellow-plastic carts for internal use at Nintendo Service Centers, although these "test carts" were never made available for purchase. All licensed US cartridges were made by Nintendo, Konami and Acclaim. For promotion of DuckTales: Remastered, Capcom sent 150 limited-edition gold NES cartridges with the original game, featuring the Remastered art as the sticker, to different gaming news agencies. The instruction label on the back included the opening lyric from the show's theme song, "Life is like a hurricane".
Is there an answer to this question: What was the closing lyric from the Duck Tales theme show?

Answer: unanswerable

QUES: Later chapters provide evidence that evolution has occurred, supporting the idea of branching, adaptive evolution without directly proving that selection is the mechanism. Darwin presents supporting facts drawn from many disciplines, showing that his theory could explain a myriad of observations from many fields of natural history that were inexplicable under the alternate concept that species had been individually created. The structure of Darwin's argument showed the influence of John Herschel, whose philosophy of science maintained that a mechanism could be called a vera causa (true cause) if three things could be demonstrated: its existence in nature, its ability to produce the effects of interest, and its ability to explain a wide range of observations.

What are the three things John Herschel maintains need to be shown to allow for a mechanism be called a true cause?
What is the answer?
ANS:
its existence in nature, its ability to produce the effects of interest, and its ability to explain a wide range of observations
