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]: Which element is mentioned?, Context: Breathing pure O2 in space applications, such as in some modern space suits, or in early spacecraft such as Apollo, causes no damage due to the low total pressures used. In the case of spacesuits, the O2 partial pressure in the breathing gas is, in general, about 30 kPa (1.4 times normal), and the resulting O2 partial pressure in the astronaut's arterial blood is only marginally more than normal sea-level O2 partial pressure (for more information on this, see space suit and arterial blood gas).
[EX A]: O2

[EX Q]: A stance that places high national and religious significance on the State of Israel is called what?, Context: Modern Orthodoxy, as a stream of Orthodox Judaism represented by institutions such as the U.S. National Council for Young Israel, is pro-Zionist and thus places a high national, as well as religious, significance on the State of Israel, and its affiliates are, typically, Zionist in orientation. It also practices involvement with non-Orthodox Jews that extends beyond "outreach (Kiruv)" to continued institutional relations and cooperation; see further under Torah Umadda. Other "core beliefs" are a recognition of the value and importance of secular studies, a commitment to equality of education for both men and women, and a full acceptance of the importance of being able to financially support oneself and one's family.
[EX A]: pro-Zionist

[EX Q]: Who ruled the people that speak siSwati in the first half of the 20th century?, 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.
