Input: Emotion
In philosophy, emotions are studied in sub-fields such as ethics, the philosophy of art (for example, sensoryemotional values, and matters of taste and sentimentality), and the philosophy of music (see also Music and emotion). In history, scholars examine documents and other sources to interpret and analyze past activities; speculation on the emotional state of the authors of historical documents is one of the tools of interpretation. In literature and film-making, the expression of emotion is the cornerstone of genres such as drama, melodrama, and romance. In communication studies, scholars study the role that emotion plays in the dissemination of ideas and messages. Emotion is also studied in non-human animals in ethology, a branch of zoology which focuses on the scientific study of animal behavior. Ethology is a combination of laboratory and field science, with strong ties to ecology and evolution. Ethologists often study one type of behavior (for example, aggression) in a number of unrelated animals.

Along with evolution, what area of study is ethology tied to?
Output: ecology

Input: Article: The control of migration, its timing and response are genetically controlled and appear to be a primitive trait that is present even in non-migratory species of birds. The ability to navigate and orient themselves during migration is a much more complex phenomenon that may include both endogenous programs as well as learning.

Now answer this question: What is a primitive trait present even in non migrating birds?

Output: migration

Article: In the United States, federal government policy promotes the use of racially categorized data to identify and address health disparities between racial or ethnic groups. In clinical settings, race has sometimes been considered in the diagnosis and treatment of medical conditions. Doctors have noted that some medical conditions are more prevalent in certain racial or ethnic groups than in others, without being sure of the cause of those differences. Recent interest in race-based medicine, or race-targeted pharmacogenomics, has been fueled by the proliferation of human genetic data which followed the decoding of the human genome in the first decade of the twenty-first century. There is an active debate among biomedical researchers about the meaning and importance of race in their research. Proponents of the use of racial categories in biomedicine argue that continued use of racial categorizations in biomedical research and clinical practice makes possible the application of new genetic findings, and provides a clue to diagnosis.

Question: What do proponents of the use of racial categories in biomedicine think it makes possible?
Ans: application of new genetic findings,

Here is a question about this article: By the 1840s, India was no longer capable of supplying the vast quantities of cotton fibers needed by mechanized British factories, while shipping bulky, low-price cotton from India to Britain was time-consuming and expensive. This, coupled with the emergence of American cotton as a superior type (due to the longer, stronger fibers of the two domesticated native American species, Gossypium hirsutum and Gossypium barbadense), encouraged British traders to purchase cotton from plantations in the United States and plantations in the Caribbean. By the mid-19th century, "King Cotton" had become the backbone of the southern American economy. In the United States, cultivating and harvesting cotton became the leading occupation of slaves.
What is the answer to this question: What was the difference that made American cotton preferred over Indian cotton?
****
So... longer, stronger fibers

The Russian Civil War was a multi-party war that occurred within the former Russian Empire after the Russian provisional government collapsed and the Soviets under the domination of the Bolshevik party assumed power, first in Petrograd (St. Petersburg) and then in other places. In the wake of the October Revolution, the old Russian Imperial Army had been demobilized; the volunteer-based Red Guard was the Bolsheviks' main military force, augmented by an armed military component of the Cheka, the Bolshevik state security apparatus. There was an instituted mandatory conscription of the rural peasantry into the Red Army. Opposition of rural Russians to Red Army conscription units was overcome by taking hostages and shooting them when necessary in order to force compliance. Former Tsarist officers were utilized as "military specialists" (voenspetsy), taking their families hostage in order to ensure loyalty. At the start of the war, three-fourths of the Red Army officer corps was composed of former Tsarist officers. By its end, 83% of all Red Army divisional and corps commanders were ex-Tsarist soldiers.
How did the Red red Army overcome their foes?
****
The answer: by taking hostages and shooting them when necessary in order to force compliance.

The problem: Answer a question about this article:
Rajasthan is[when?] earning Rs. 150 million (approx. US$2.5 million) per day as revenue from the crude oil sector. This earning is expected to reach 250 million per day in 2013 (which is an increase of 100 million or more than 66 percent). The government of India has given permission to extract 300,000 barrels of crude per day from Barmer region which is now 175,000 barrels per day. Once this limit is achieved Rajasthan will become a leader in Crude extraction in Country. Bombay High leads with a production of 250,000 barrels crude per day. Once the limit if 300,000 barrels per day is reached, the overall production of the country will increase by 15 percent. Cairn India is doing the work of exploration and extraction of crude oil in Rajasthan.
The leader in Indian crude oil production at 250,000 barrels per day is what region?
****
The answer:
Bombay High
