Context and question: Many bird species migrate to take advantage of global differences of seasonal temperatures, therefore optimising availability of food sources and breeding habitat. These migrations vary among the different groups. Many landbirds, shorebirds, and waterbirds undertake annual long distance migrations, usually triggered by the length of daylight as well as weather conditions. These birds are characterised by a breeding season spent in the temperate or polar regions and a non-breeding season in the tropical regions or opposite hemisphere. Before migration, birds substantially increase body fats and reserves and reduce the size of some of their organs. Migration is highly demanding energetically, particularly as birds need to cross deserts and oceans without refuelling. Landbirds have a flight range of around 2,500 km (1,600 mi) and shorebirds can fly up to 4,000 km (2,500 mi), although the bar-tailed godwit is capable of non-stop flights of up to 10,200 km (6,300 mi). Seabirds also undertake long migrations, the longest annual migration being those of sooty shearwaters, which nest in New Zealand and Chile and spend the northern summer feeding in the North Pacific off Japan, Alaska and California, an annual round trip of 64,000 km (39,800 mi). Other seabirds disperse after breeding, travelling widely but having no set migration route. Albatrosses nesting in the Southern Ocean often undertake circumpolar trips between breeding seasons.
What is the flight range of shoebirds?
Answer: 4,000 km (2,500 mi)
Context and question: The relationship between ethnic Greek identity and Greek Orthodox religion continued after the creation of the Modern Greek state in 1830. According to the second article of the first Greek constitution of 1822, a Greek was defined as any Christian resident of the Kingdom of Greece, a clause removed by 1840. A century later, when the Treaty of Lausanne was signed between Greece and Turkey in 1923, the two countries agreed to use religion as the determinant for ethnic identity for the purposes of population exchange, although most of the Greeks displaced (over a million of the total 1.5 million) had already been driven out by the time the agreement was signed.[note 1] The Greek genocide, in particular the harsh removal of Pontian Greeks from the southern shore area of the Black Sea, contemporaneous with and following the failed Greek Asia Minor Campaign, was part of this process of Turkification of the Ottoman Empire and the placement of its economy and trade, then largely in Greek hands under ethnic Turkish control.
 How did the original Constitution not identify its society members?
Answer: unanswerable
Context and question: Ahom Kingdom (1228–1826) was a kingdom and tribe which rose to prominence in present-day Assam early in the thirteenth century. They ruled much of Assam from the 13th century until the establishment of British rule in 1838.

From thirteenth till seventeenth century, repeated attempts were made by the Muslim rulers of Delhi to invade and subdue Ahoms, however the Ahoms managed to maintain their independence and ruled themselves for nearly 600 years.
With what religion did the Ahom merge?
Answer:
Hindu
