[EX Q]: Question: What was the population of the Principality of Samtskhe while Sargis II Jaqeli was the ruler? Passage:Sargis II Jaqeli () (1271 – 1334) was a Georgian prince (mtavari) and ruler of Principality of Samtskhe from 1306 to 1334. He was a son of Prince Beka I Jaqeli. During his father's reign Sargis participated in many campaigns. In 1290s Azat Mousa, leader of the Anatolian Turkoman tribes, attacked Samtskhe. Beka Jaqeli appointed Sargis as a commander of army and ordered him to stop Turks near village Vashlovani. Around 1303, Sargis defeated Turkoman tribes and expelled them from Meskhetian lands. In 1306, after his father's death, Sargis ascended the Atabeg's throne. He was made Amirspasalar by his nephew, King George V "the Brilliant". After Sargis II's death, his son Qvarqvare became a new Prince of Meskheti, also the vassal of Georgian kingdom.

[EX Q]: Question: Is serpentine blue like Boron? Passage:The earliest recorded blue diamond, the Hope Diamond, was discovered in India, in the Kollur mine in the Guntur district of Andhra Pradesh (which at the time was part of the Golconda kingdom), in the seventeenth century. However, blue diamonds have also been discovered in the Cullinan Mine in South Africa and the Golconda region. A few blue diamonds have been discovered in the Argyle Mine in Western Australia as well, and are offered at their annual Argyle Tender when they are found. It is thought that blue diamonds, unlike most other diamonds, are formed in the lower part of Earth’s mantle, and that the boron creating their blue color originates from serpentinite carried down to the mantle by subducting ocean tectonic plates.

[EX Q]: Question: Which mountains the Dyke climbed were the highest? Passage:In his spare time during his working life, he climbed the Cape Peninsula mountains, the Hottentots-Holland mountains, and nearby ranges, all of which are spectacular examples of Fynbos, including Peninsula Granite Fynbos, Peninsula Sandstone Fynbos and a number of related biomes. Later, when the railway administration moved to Johannesburg, he continued his explorations in various parts of the Drakensberg mountains, as well as on visits to Lesotho. On such excursions he collected avidly and sent specimens to Dr Rudolf Marloth. He extended his explorations to other regions as well; for example, while climbing the Cockscomb Mountains in the Winterberg range near Uitenhage he discovered a hitherto unrecognised species of Protea, later named Protea dykei Phill (now seen as a synonym of Protea rupicola). On Matroosberg in the Hex River Mountains, he discovered a new species of "everlasting", flowers that in those days were generally included in the genus Helichrysum. That species was described by Harry Bolus under the name Helichrysum dykei Bolus. The genus has since been split however, and the species has been assigned to another genus, as Syncarpha dykei (Bolus) B. Nord. Dyke's name also appears in the names of Erica dykei L. Bolus (= Erica thodei Gilg) and Lessertia dykei L. Bolus.
