In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Under what kind of model is Swaziland governed?, Context: At no more than 200 kilometres (120 mi) north to south and 130 kilometres (81 mi) east to west, Swaziland is one of the smallest countries in Africa. Despite its size, however, its climate and topography is diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is primarily ethnic Swazis whose language is siSwati. They established their kingdom in the mid-18th century under the leadership of Ngwane III; the present boundaries were drawn up in 1881. After the Anglo-Boer War, Swaziland was a British protectorate from 1903 until 1967. It regained its independence on 6 September 1968.
[EX A]: kingdom

[EX Q]: What is a prerequisite for weight to play a factor in conductivity?, Context: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.
[EX A]: constant pressure and temperature

[EX Q]: What classification did Poland's governance structure have?, Context: According to heraldic sources 1,600 is a total estimated number of all legal ennoblements throughout the history of Kingdom of Poland and Polish-Lithuanian Commonwealth from the 14th century onward (half of which were performed in the final years of the late 18th century).
