Problem: Though based upon Mahayana, Tibeto-Mongolian Buddhism is one of the schools that practice Vajrayana or "Diamond Vehicle" (also referred to as Mantrayana, Tantrayana, Tantric Buddhism, or esoteric Buddhism). It accepts all the basic concepts of Mahayana, but also includes a vast array of spiritual and physical techniques designed to enhance Buddhist practice. Tantric Buddhism is largely concerned with ritual and meditative practices. One component of the Vajrayana is harnessing psycho-physical energy through ritual, visualization, physical exercises, and meditation as a means of developing the mind. Using these techniques, it is claimed that a practitioner can achieve Buddhahood in one lifetime, or even as little as three years. In the Tibetan tradition, these practices can include sexual yoga, though only for some very advanced practitioners.
Psycho-physical energy is harnessed through what?
The answer is the following: ritual

The basis for classical economics forms Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. Smith criticized mercantilism, advocating a system of free trade with division of labour. He postulated an "invisible hand" that regulated economic systems made up of actors guided only by self-interest. Karl Marx developed an alternative economic theory, called Marxian economics. Marxian economics is based on the labor theory of value and assumes the value of good to be based on the amount of labor required to produce it. Under this assumption, capitalism was based on employers not paying the full value of workers labor to create profit. The Austrian school responded to Marxian economics by viewing entrepreneurship as driving force of economic development. This replaced the labor theory of value by a system of supply and demand.
Who is Marxian economics named after?
Karl Marx

Input: Nutrition
In 1896, Eugen Baumann observed iodine in thyroid glands. In 1897, Christiaan Eijkman worked with natives of Java, who also suffered from beriberi. Eijkman observed that chickens fed the native diet of white rice developed the symptoms of beriberi but remained healthy when fed unprocessed brown rice with the outer bran intact. Eijkman cured the natives by feeding them brown rice, discovering that food can cure disease. Over two decades later, nutritionists learned that the outer rice bran contains vitamin B1, also known as thiamine.

What group of natives suffered from beriberi?
Output: Java

Input: Article: Predators may increase the biodiversity of communities by preventing a single species from becoming dominant. Such predators are known as keystone species and may have a profound influence on the balance of organisms in a particular ecosystem. Introduction or removal of this predator, or changes in its population density, can have drastic cascading effects on the equilibrium of many other populations in the ecosystem. For example, grazers of a grassland may prevent a single dominant species from taking over.

Now answer this question: What is the title of a predator that maintains balance with an ecosystem?

Output: keystone species

Article: The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). Early carbon filaments had a negative temperature coefficient of resistance as they got hotter, their electrical resistance decreased. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducing its resistance and causing it to draw even more power and heat even further. In the "flashing" process, carbon filaments were heated by current passing through them while in an evacuated vessel containing hydrocarbon vapor (usually gasoline). The carbon deposited on the filament by this treatment improved the uniformity and strength of filaments as well as their efficiency. A metallized or "graphitized" filament was first heated in a high-temperature oven before flashing and lamp assembly. This transformed the carbon into graphite which further strengthened and smoothed the filament. This also changed the filament to have a positive temperature coefficient, like a metallic conductor, and helped stabilize the lamp's power consumption, temperature and light output against minor variations in supply voltage.

Question: What properties of graphite improved the filament?
Ans: further strengthened and smoothed the filament

Input: European Central Bank
This changed with the recent sovereign-debt crisis. The ECB always could, and through the late summer of 2011 did, purchase bonds issued by the weaker states even though it assumes, in doing so, the risk of a deteriorating balance sheet. ECB buying focused primarily on Spanish and Italian debt. Certain techniques can minimise the impact. Purchases of Italian bonds by the central bank, for example, were intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank.

What debt did the ECB focus on abtaining?
Output:
Spanish and Italian
