Article: The American Civil War caught both sides unprepared. The Confederacy hoped to win by getting Britain and France to intervene, or else by wearing down the North's willingness to fight. The U.S. sought a quick victory focused on capturing the Confederate capital at Richmond, Virginia. The Confederates under Robert E. Lee tenaciously defended their capital until the very end. The war spilled across the continent, and even to the high seas. Most of the material and personnel of the South were used up, while the North prospered.

Question: What was the Union's original war aim?
Ans: capturing the Confederate capital at Richmond, Virginia


Here is a question about this article: A core problem in the study of early Buddhism is the relation between dhyana and insight. Schmithausen, in his often-cited article On some Aspects of Descriptions or Theories of 'Liberating Insight' and 'Enlightenment' in Early Buddhism notes that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the Rupa Jhanas, is a later addition to texts such as Majjhima Nikaya 36.[page needed]
What is the answer to this question: Later edition of texts such as what has the Rupa Jhanas?
****
So... Majjhima Nikaya


The problem: Answer a question about this article:
As a result of the 19th century Russo-Persian wars, the Russians took over the Caucasus, and Iran irrevocably lost control over its integral territories in the region (comprising modern-day Dagestan, Georgia, Armenia, and Azerbaijan), which got confirmed per the treaties of Gulistan and Turkmenchay. The area to the north of the river Aras, among which the contemporary Republic of Azerbaijan, eastern Georgia, Dagestan, and Armenia, were Iranian territory until they were occupied by Russia in the course of the 19th century.
The Gulistan and Turkmenchay treaties between Iran and Russia confirmed what?
****
The answer: Iran irrevocably lost control over its integral territories in the region


Problem: Please answer a question about the following article about High-definition television:
Since 1972, International Telecommunication Union's radio telecommunications sector (ITU-R) had been working on creating a global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 also led to the acceptance of recommendations ITU-R BT.709. In anticipation of these standards the Digital Video Broadcasting (DVB) organisation was formed, an alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI.
What does ITU-R stand for?
A: International Telecommunication Union's radio telecommunications sector

There are certain characteristics of adolescent development that are more rooted in culture than in human biology or cognitive structures. Culture has been defined as the "symbolic and behavioral inheritance received from the past that provides a community framework for what is valued". Culture is learned and socially shared, and it affects all aspects of an individual's life. Social responsibilities, sexual expression, and belief system development, for instance, are all things that are likely to vary by culture. Furthermore, distinguishing characteristics of youth, including dress, music and other uses of media, employment, art, food and beverage choices, recreation, and language, all constitute a youth culture. For these reasons, culture is a prevalent and powerful presence in the lives of adolescents, and therefore we cannot fully understand today's adolescents without studying and understanding their culture. However, "culture" should not be seen as synonymous with nation or ethnicity. Many cultures are present within any given country and racial or socioeconomic group. Furthermore, to avoid ethnocentrism, researchers must be careful not to define the culture's role in adolescence in terms of their own cultural beliefs.

What is a challenge researchers face when studying culture and adolescents?
Answer: not to define the culture's role in adolescence in terms of their own cultural beliefs


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 much does it cost to develop a new drug?
about 1.3 billion
