[EX Q]: The Treaty of Tordesillas (Portuguese: Tratado de Tordesilhas (ttau tuzi), Spanish: Tratado de Tordesillas (tatao e toesias)), signed at Tordesillas on June 7, 1494, and authenticated at Setubal, Portugal, divided the newly discovered lands outside Europe between the Portuguese Empire and the Crown of Castile, along a meridian 370 leagues west of the Cape Verde islands, off the west coast of Africa. This line of demarcation was about halfway between the Cape Verde islands (already Portuguese) and the islands entered by Christopher Columbus on his first voyage (claimed for Castile and Leon), named in the treaty as Cipangu and Antilia (Cuba and Hispaniola).

[EX Q]: Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later. Gold rushes to Pilgrim's Rest and Barberton were precursors to the biggest discovery of all, the Main Reef / Main Reef Leader on Gerhardus Oosthuizen's farm Langlaagte, Portion C, in 1886, the Witwatersrand Gold Rush and the subsequent rapid development of the gold field there, the biggest of them all.

[EX Q]: It originated from the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron would be assigned an admiral as its head, who would command from the centre vessel and direct the activities of the squadron. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships which would bear the brunt of a naval battle. In the rear of the naval squadron, a third admiral would command the remaining ships and, as this section of the squadron was considered to be in the least danger, the admiral in command of the rear would typically be the most junior of the squadron admirals. This has survived into the modern age, with the rank of rear admiral the most-junior of the admiralty ranks of many navies.
