The problem: Answer a question about this article:
After the success of quantum electrodynamics, Feynman turned to quantum gravity. By analogy with the photon, which has spin 1, he investigated the consequences of a free massless spin 2 field, and derived the Einstein field equation of general relativity, but little more. The computational device that Feynman discovered then for gravity, "ghosts", which are "particles" in the interior of his diagrams that have the "wrong" connection between spin and statistics, have proved invaluable in explaining the quantum particle behavior of the Yang–Mills theories, for example, QCD and the electro-weak theory.
What equation did Feyman derive?
****
The answer: Einstein field equation of general relativity


Problem: Please answer a question about the following article about Armenia:
On 10 October 2009, Armenia and Turkey signed protocols on normalisation of relationships, which set a timetable for restoring diplomatic ties and reopening their joint border. The ratification of those had to be made in the national parliaments. In Armenia it passed through the required by legislation approval of the Constitutional Court and was sent to the parliament for the final ratification. The President had made multiple public announcements, both in Armenia and abroad, that as the leader of the political majority of Armenia he assured the ratification of the protocols if Turkey also ratified them. Despite this, the process stopped, as Turkey continuously added more preconditions to its ratification and also "delayed it beyond any reasonable time-period".
How did Turkey thwart the ratification of these protocols?
A: continuously added more preconditions to its ratification

Magadha (Sanskrit: मगध) formed one of the sixteen Mahā-Janapadas (Sanskrit: "Great Countries") or kingdoms in ancient India. The core of the kingdom was the area of Bihar south of the Ganges; its first capital was Rajagriha (modern Rajgir) then Pataliputra (modern Patna). Magadha expanded to include most of Bihar and Bengal with the conquest of Licchavi and Anga respectively, followed by much of eastern Uttar Pradesh and Orissa. The ancient kingdom of Magadha is heavily mentioned in Jain and Buddhist texts. It is also mentioned in the Ramayana, Mahabharata, Puranas. A state of Magadha, possibly a tribal kingdom, is recorded in Vedic texts much earlier in time than 600 BC. Magadha Empire had great rulers like Bimbisara and Ajatshatru.

Of what was Magadha one of sixteen?
Answer: Mahā-Janapadas


Problem: Himachal is extremely rich in hydro electric resources. The state has about 25% of the national potential in this respect. It has been estimated that about 20,300MW of hydro electric power can be generated in the State by constructing various major, medium, small and mini/micro hydel projects on the five river basins. The state is also the first state in India to achieve the goal of having a bank account for every family.[citation needed] As per the current prices, the total GDP was estimated at ₹ 254 billion as against ₹ 230 billion in the year 2004–05, showing an increase of 10.5%. The recent years witnessed quick establishment of International Entrepreneurship. Luxury hotels, food and franchisees of recognised brands e.g. Mc Donalds, KFC and Pizza hut have rapidly spread.
What is current GDP estimated at?
The answer is the following: ₹ 254 billion

Here is a question about this article: Peace between England and the Netherlands in 1688 meant that the two countries entered the Nine Years' War as allies, but the conflict—waged in Europe and overseas between France, Spain and the Anglo-Dutch alliance—left the English a stronger colonial power than the Dutch, who were forced to devote a larger proportion of their military budget on the costly land war in Europe. The 18th century saw England (after 1707, Britain) rise to be the world's dominant colonial power, and France becoming its main rival on the imperial stage.
What is the answer to this question: In which century did Britain become the world's dominant colonial power?
